A first look at the Dive Rite HP50 Lighting System

Dive Rite introduced a new lighting system, the HP50. It’s a modular system which can grow with your needs as a diver. While not cheap to begin with, it’s an outstandingly capable light system!

The first version of using the HP50 is to set it up as a regular hand-held scuba torch. But don’t be surprised when you switch it on and have a super-bright 3,500 lumens light! That’s by far more than what you usually have with a standard torch! In this hand-held configuration you can expect a burn time of 1.5 hours before your battery is empty.

If you are doing longer dives then instead of a standard torch configuration you can use battery packs which give you up to 6.5 hours of light before the pack is empty. There are two packs available that come in canister form. The Slimline provides enough power for 4.5 hours of burn time while the Expedition canister has enough power for a burn time of 6.5 hours at full brightness!

As a torch the light weighs 1.4 pounds. It measures 2 inches in diameter and 3.5 inches in length. The measurements and weight make it easy to handle and hold. The head can be paired with a standard metal Goodman handle. If you prefer otherwise, there’s also the option to use a soft hand mount.

The table below shows the detailed information for the three different variants of the HP50 lighting system by Dive Rite:

​HP50 Handheld Torch

Oceanic ProPlus X Dive Computer

The Oceanic ProPlus X is a console style dive computer. It is a full-featured scuba computer that pretty much has any possible feature a diver with any experience level could ask for.

The screen is simply brilliant and navigation is easy with four buttons. The large display is very clean and shows all important information without confusing you. The display is one of the largest you can get on any scuba diving computer to date.

Oceanic ProPlus X Dive Computer

Air integration is through the high pressure hose. The Oceanic Pro Plus X can deal with up to 4 air and Nitrox mixes leaving no desires unfulfilled for an experienced diver.


Review Summary

Experience Level

Designed for intermediate and experienced divers. However, beginners should have no problems with it.

STYLE

Gauge style scuba computer with quick disconnect from hose.

Ease of Use

Four button design making it easy to use. No touchscreen.

Price Level

Pretty high in price. Offers all features needed for most divers and as such not overpriced!

We Don't Like

  • 4 button navigation instead of touchscreen
  • No wireless air integration

Summary:

The Oceanic ProPlus X pretty much has everything you want and need. From a clear and colorful display to 4 gas mixes to automatic altitude adjustments and built-in compass. You get it all.


On top of that you also get Oceanic’s dual algorithm. The battery is rechargeable and as such it’s pretty easy to make sure you always have enough battery. The memory on board is enough for 99 dives. Last but not least, the connectivity to your computer, tablet or phone is through Bluetooth allowing you to download dive data even while you’re still on the boat going back to shore.


There’s really not much you wouldn’t like. The only improvement we would wish for is to have a touchscreen display. That would propel the ease of use to the next level. Having said that, the four button navigation is simple enough yet you will need to get used to the use of the buttons and pressing them short or long for different features!


Oceanic ProPlus X Dive Computer

The highlight of the Oceanic ProPlus X is clearly the display. It’s clear and shows all information with crisp fonts and graphics.

It’s also a plus to have a rechargeable battery so you won’t depend on having batteries available when you are on a dive boat and realize that your battery gets low.

The Pro Plus X supports three dive modes:

  • Air
  • Nitrox
  • Gauge
 Being a console device it wouldn’t make any sense to have or to expect a freediving mode.



Capabilities

The Oceanic ProPlus X offers nearly any feature you could ever want. The price reflects that but is overall reasonable considering that you get everything in one single device and won’t have to buy a cheaper scuba computer together with a pressure gauge and compass. The Pro Plus X combines all that into one device and in the end might even end up saving you money!

The display is nothing short of brilliant. While the VTX is using an OLED display, the ProPlus X uses the TFT technology. This reduces glare and makes it overall easier to read. The colors and contrast are a little lower but it’s in no way noticeable.
Oceanic Pro Plux X from back

Gas Mixes

The diving computer supports up to 4 gas mixes. These can range from 21% to 100% O2. Gas switching can be performed under water during a dive. 

Air Integration

Air integration on the Oceanic ProPlus X is handled through a high-pressure hose that connects to your regulator. While you do end up having a hose that can get in the way, there's no need for additional equipment like a pressure gauge. With wireless air integration a sensor can easily fail or run out of battery which is not a concern to have when you get the tank pressure through a hose.

Compass and Temperature

The device features a compass that is easy to use. It also measures the temperature and shows it on the screen. Other displayed information shows the remaining tank pressure and air time remaining, dive time remaining as well as elapsed dive time, depth, battery level and no decompression time remaining. Bar graphs represent the nitrogen tissue loading, air time remaining, oxygen loading and ascent rate.

The temperature is displayed on the screen and constantly updated.

Display

The display comes with a solid backlight. It is using the OceanicGlo technology that is activated through a button as well as the SmartGlo backlight which is sensor activated. This helps to produce a consistent intensity depending on your surroundings. You can adjust the time that the backlight is on to increase battery life.

All data can be viewed in imperial or metric units. You can easily switch between those through the settings. The time can also either be displayed in 12 or 24 hour format. Additionally, you have a built-in calendar and a 12/24 hour time to fly countdown. You also get a calculated desaturation countdown timer.

Battery Life

The ProPlus X uses a rechargeable battery. The air integration is handled through a high-pressure hose and as such doesn’t need a battery to measure the pressure in the tank. Battery life on the device is between 35 and 60 hours depending on the use and features used. For example using the backlight a lot will reduce battery life significantly.

Alarms

Alarms and warning are clearly displayed on the screen. They are also available in audible form and you have to acknowledge them through pressing a button.

You can set alarms and warning levels for

  • “Turn Around” pressure
  • “Ending” pressure
  • FO2 Alarm
  • Max. Depth
  • Elapsed Dive Time
  • Max. Nitrogen Tissue Loading
  • Dive Time Remaining
  • High O2
  • High PO2

Technical Capabilities

Similar to all other Oceanic dive computers, the ProPlus X also features the dual algorithm technology. This allows you to switch between a Pelagic Z+ (Buhlmann ZHL-16C basis) or the Pelagic DSAT (Spencer/Powell model). You can also add a conservatism factor to each of the algorithms.

The ProPlus X can handle up to four different gas mixes. Each mix can be set to have O2 levels between 21 and 100 percent. You can manually switch between the gas mixes through a menu selection. The O2 levels can be preset on land.

Another handy feature is that the Pro plus X automatically adjusts the altitude settings. The algorithm is based on NOAA. The altitude is automatically adjusted between 2,000  and 14,000 ft (610 to 4,200 m).

Dive Log and Connectivity

The on-board dive log has a capacity to hold data for up to 99 dives. You can then connect through Bluetooth with your computer, tablet or even phone to offload the data. You won’t need any more cables to connect which in the end will save you money as you usually have to pay for the optional connectivity cabling.

Missing Functionality

There are really no main features and functions that are missing. For technical diving it would be great to have a Trimix capability but for 95% or more of the divers this is not needed anyway.

Pros and Cons

There’s seriously not much you wouldn’t like about this dive computer. It feels like splitting hair trying to find negatives about it.

The pros clearly outweigh the negatives in this case. Using four buttons for navigation instead of a touchscreen is somewhat personal preference and after going through the manual once and playing with the Pro Plus X for a little while you will not feel like you’re missing anything compared to other devices.

Conclusion

The Oceanic ProPlus X is a full-featured dive computer that will satisfy the needs of nearly ever diver. Nearly any feature you can imagine is available with the exception of dealing with Trimix.

Pricing is on the higher side. However, you save a bunch of cash by not having to purchase additional wireless air transmitters or optional connectivity kits and cables. You also won’t need an additional pressure gauge and compass as it’s all built-in.

The Pro Plus X is easy to use and as such even beginners won’t have problems using it. Overall, it’s designed for intermediate to experienced divers that love to dig through the data and display all pertinent information on the screen.

 The screen is large and allows to display a lot of data. It even features a number of bar graphs that are easy to read.

Who wouldn't like it?

If you prefer to have a wrist dive computer and not a console mounted device then this is clearly not the right gadget for you. Also, if you insist on having a touchscreen display then this will not be the right scuba computer for you. Navigation is performed through four buttons and is easily mastered.

Data oriented divers will be happy with the Pro Plus X. It offers a large number of data points and you have a strong dive planning capability. The on-board log is large and allows to store and review the last 99 dives.

Overall, this is one of the most capable scuba diving computer you can get. It’s pricy but the features justify the price. The display is simply gorgeous and easy to read. The navigation is easy enough to even allow beginner divers not to be overwhelmed!

Suunto Cobra 3 Diving Computer Console Review

​The Suunto Cobra 3 is designed for new recreational divers who would like to combine their pressure gauge and their dive computer into one piece of equipment. This is not a typical wrist mounted computer and can be great for those looking for a gauge design dive computer.

Suunto Cobra 3 from the side

This diving computer is not designed for professional divers and does not have many of the technical features that would be needed on more advanced dives. This basic diving computer is ideal for new divers who want something that is simple to use but still offers some room to grow.

The Suunto Cobra 3 does offer room to grow with things like nitrox and dual gas mixtures. So, even if it is the first dive computer you purchase, you should have it for quite some time.

Review Summary

Experience Level

​The Suunto Cobra 3 is an easy to use dive computer with two navigation buttons.​

STYLE

​For divers looking for a gauge style dive computer, the Suunto Cobra 3 is going to be a great purchase. ​

Ease of Use

​The two-button navigation for the Suunto Cobra 3 is fairly simple once you get used to the short and long press navigation. ​

Price Level

  • No Automatic Altitude Adjustment

Summary:

The Suunto Cobra 3 is a great beginner dive computer because of the integrated features. The audio and visual alarms allow new divers to be aware of vital diving data without overwhelming them with too much technical data. Air integration means that you do not need an additional air gauge to monitor your air pressure, leaving you with fewer hoses to get tangled in or drag across the coral.


The two-button navigation is good in theory, but the long and short hold design of navigation leaves a little to be desired. It is easy to get frustrated when navigating to the screen or programming features that you want for the computer.


The compass design on the computer isn’t the best. You do not get a full compass mode and are only able to see your locked bearing through a series of small graphics on the computer. It can be easy to forget what the graphics mean, making it even easier to lose your bearing.


Finally, while there are adjustable gas mixes and great altitude adjustments available in the Suunto Cobra 3, there is no automatic altitude adjustment. This could be dangerous for newer divers who may not fully understand the impact altitude has on their diving capabilities.
Suunto Cobra 3 viewed from the front

The Suunto Cobra 3 is an easy to use scuba computer console with two navigation buttons. The three line display makes for easy reading, even though it may be a little bit crowded.

It attaches through hoses and is not worn on your wrist. You can have air integration through a high-pressure hose on your regulator.

The navigation happens through two buttons. Each button has two functions that are accessed through either a short press or a long press. This can be a little frustrating if you’re not used to this style of navigation on the computer.

The price for a wrist computer and a pressure gauge together would be equal to or even less than this computer. There are other options at this price point that have better design features.




Capabilities

The Suunto Cobra 3 targets the beginner and intermediate diver. If you are an experienced or technical diver and you want all the bells and whistles then this is not the best choice for you!

It offers three different dive modes:

  • Gauge
  • Air
  • Nitrox
Suunto Cobra 3 from the side

Gas Mixes

There are two gas mixes allowed with the Suunto Cobra 3, and the oxygen rates can be from 21%-99%. Nitrox works well with the Cobra 3 and divers with their nitrox certification will not be disappointed when they have this computer to dive with.

Air Integration

The Suunto Cobra 3 has a slightly different air integration than other dive computers. It integrates through a high-pressure hose connection onto your regulator. Many other diving computers will use a wireless node to send data to the computer to integrate air pressure data. This unique feature allows divers to avoid having redundant equipment like a pressure gauge in case the sensor node fails.

Compass and Temperature

The water temperature is displayed in either centigrade or Fahrenheit on the Suunto Cobra 3. There is also a temperature compensated pressure sensor that is calibrated complying with EN 13319.

It also offers an integrated 3D tiltable compass. Unfortunately, you do not get a full compass view but instead you'll only see your locked bearing.It needs some time to remember what the graphic represents and it can easily be confused. It might be best to have a scuba diving compass in addition to what is offered through the console.

Display

The display is divided into three lines. That's similar to the setup known from the Vyper Novo and Zoop Novo. It's easy to read yet can become a little cluttered with all the data being displayed.

The backlight has several timeout options. This is a great feature on the Suunto Cobra 3 because it allows you to preserve the life of your dive battery. The timeout of the backlight ranges from 2 seconds through 60 seconds, giving you plenty of options to suit your needs.

Battery Life

The Suunto Cobra 3 has a battery life of 1.5 years. Suunto does not recommend that users replace the battery themselves because of the risk of water leaking into the battery compartment. Keep in mind that the data is not retained when the battery is swapped out because this is not a hot swap featured dive computer.

Alarms

The alarm system consists of both audio and visual alarms. Many low-level alarms are only audio and may consist of short beeps, or interval beeps to alert you to an issue that needs attention. More serious alerts combine audible beeps with activation of the backlight. For life-threatening alerts, you will hear continuous beeps, and the backlight will be activated. These life-threatening alerts can be when the maximum ascent rate of 10 m per second is violated or if the decompression ceiling depth is exceeded.

Maximum depth or dive time exceeded, an alarm time reached all get both audio and visual alarms. Nitrox has its own set of alarms to alert you of your maximum safe partial pressure of oxygen levels.

Technical Capabilities

The algorithms used on the Suunto Cobra 3 is based on a reduced gradient bubble model. The RGBM predicts gas build-up in the blood and tissues of divers. It is an advancement on the how they used to model gases which did not predict free gas. To optimize the safety in the RGBM algorithm, you must adjust your altitude settings.

Dive Log and Connectivity

The Cobra 3 connects to your PC through a USB dongle and is compatible with Movescount, Suunto’s mobile application that functions as a dive log. Movescount functions with the DM4 software allowing you to download your dive data to the mobile app anywhere you are.

Missing Functionality

The biggest missing feature from this dive computer is the functionality of the compass. The very basic waypoint setting and minimal graphic display of 90° or 180° off of your waypoint can be difficult to navigate. Using the compass settings in this dive computer may not be useful for new divers or inexperienced navigators.

It would also be nice if there were an option to use this computer as a wrist mount. While having it look like a traditional pressure gauge and function similarly allows you to eliminate an additional piece of equipment; not having your data on your wrist can be a hindrance when diving.

Pros and Cons

There’s a lot to like about the Suunto Cobra 3. The battery is user replaceable. Although the manufacturer recommends you take it to a service station. You still can replace the battery yourself. There are instructions for how to do this in the owners manual.

The multiple setting backlight display is one of the best features. Many people like to have a long backlight for looking at their diving computer while others prefer a short backlight for quick glimpses of information. Whether you’re trying to preserve your battery life or take a long look at dive information, the Suunto Cobra 3 will have a setting right for you.

The three line display makes it easy to read all of the relevant dive information. Some of the information is attempted to be crammed into a fourth line, but it is not that often. The big block view letters are easy to read even for people with slight visual impairments.

Unfortunately, the navigation buttons on the Suunto Cobra 3 itself leave a little to be desired. The long and short press navigation options can leave users frustrated when attempting to get to the right screen especially if they're underwater.

The lack of an actual compass display is annoying. You do have the ability to set a waypoint marker. The tiny graphics to represent where you need to go are frustrating to read and could leave inexperienced navigators lost.

Finally, some people may find that only having a three line display leaves it cluttered. Especially when you’re at your safety stop, and the additional line of information is popped onto that display. Having a fourth line crammed in between your second and third rows is ugly. It can be hard to look at and harder to read.

Conclusion

Altogether this is a great dive computer. While you pay a little bit more for the design of the Suunto Cobra 3, it is designed like a gauge instead of a wristwatch. It does have all of the features you’ve come to expect from an introductory dive computer.

There are plenty of features on this dive computer that will leave everyone satisfied. It looks sleek, and the backlight brightly illuminates all of the data that you need to see. The vital alarms are easily noticed when the backlight begins to flash because of the bright display.

Who wouldn't like it?

Divers who have been diving for a long time may find that this dive computer is a bit rudimentary. Suunto, the Cobra 3 manufacturer, even says that this computer is for a recreational beginner diver and should not be used by professionals or technical divers.

It simply does not have enough information to be useful in a technical or professional diving situation. This is especially true considering that the maximum depth is 100 m and the operating temperature is fairly limited.

Divers who don’t like having a lot of wires hanging from their BC or their tank are not going to enjoy this computer. Because it is connected to a high-pressure hose on the regulator, you will have additional wires to manage during your dive. Having lots of hoses can lead to an exhausting dive if you’re not used to managing that type of equipment.

Summary:

The Suunto EON Steel dive computer has a rechargeable battery setting it apart from the competition. There are plenty of audio and visual alarms, but the three levels of alarm can make it a little complicated to tell what’s important and what’s not. This is a technical diving computer and may be overwhelming for new divers. The automatic start and large onboard dive log can make this a great dive computer for beginners because they will not have to remember to dump their dive log repeatedly.

Mares Smart in Black and Grey

The Suunto EON Steel is an amazing technical scuba computer. This high-end diving computer has more features than a beginner will ever need or use. A beginning diver may find that this dive computer is intimidating and that they have a hard time finding the information they need.

The display is condensed in a way that gives you all of the information you need without overwhelming you. All of the alarms and alerts flash brightly on the screen giving it a unique look.​

The navigation is performed through three buttons in addition to the touch display. It may take some practice before you are fully confident in your ability to navigate this technical diving computer.​

There are many add-ons that you can get including air integration and attachments. The device itself is rechargeable which is a rare feature in dive computers making it worth its weight in gold.




Capabilities

There is no doubt that the EON Steel targets the technical and very experienced diver.

It offers five different dive modes:

  • Gauge
  • Air
  • Nitrox
  • Trimix
  • CCR
Suunto EON Steel Bottom View

There are many different functions housed inside the Suunto EON Steel dive computer. On the main display screen, you can see your present depth, active gas, dive time, tank pressure, safety stop, and battery time. Additional displays include:

  • No-Fly Time​
  • Surface Interval Time
  • Battery Status
  • Battery Level
  • Tank Gas Pressure Information
  • Tank Pod Information
  • Decompression Ceiling and Safety Stop Time
  • Ascent Rate
  • Partial Pressure of Oxygen

​Gas Mixes

The Suunto EON Steel dive computer allows divers to choose from air, Nitrox or Trimix. The three options will have their own displays on the screen allowing divers to see their ppO2 maxes. In nitrox, only the oxygen percentage is displayed, and in Trimix; oxygen and helium percentage are displayed.

Air Integration

There is an option for air integration when using the Suunto EON steel dive computer. Air integration is available through a separate attachment. This attachment is available for purchase at an additional cost.

Compass and Temperature

​Both temperature and compass features are integrated on the Suunto EON Steel dive computer. To have the temperature displayed on the main screen, you have to customize your display. The compass includes tilt compensation. The compass does need to be calibrated and a calibration icon will appear when you enter compass mode. There are YouTube videos available to show you how to calibrate your compass properly.

Display

​There is no backlight option because this is a digital display. You can adjust the brightness of the display which will affect the overall battery life of the Suunto EON Steel dive computer. Because the battery is rechargeable having a bright display should not be a huge worry. You can recharge your batteries in between dives without worrying about having to send it off to a dive store or the manufacturer.

Alarms

​Suunto has three levels of alarm built-in to the EON Steel dive computer. Having so many alarms can make it difficult for the user to understand whether or not the audible or visual alarm is something that is life-threatening. According to Suunto the different levels alarm, warning, and notifications; are designed to be scrollable pop-up messages that will display on the screen until conditions return to normal.

Alarms are considered a critical event and will always require immediate action. When an alarm situation is resolved (for instance, you ascend back to your safety stop depth after violating your safety stop), the alarm will stop automatically. Here are the following alarms found on the Suunto dive computer:

  • Ascent Speed Exceeded
  • Decompression Ceiling Broken
  • Partial Pressure of Oxygen Exceed Safe Level
  • Partial Pressure of Oxygen Below Safe Level

Warnings are events that can impact your health and safety if you do not take action but do not require immediate attention. Acknowledging a warning can be done on the Suunto EON steel dive computer by pressing any button. The following are warnings available on the Suunto dive computer:

  • ​Central Nervous System Toxicity 100% Limit
  • Recommended Daily Limit for Oxygen Tolerance Reached
  • Depth Exceeds Your Depth Alarm Limit
  • Dive Times Exceeds Your Dive Time Alarm Limit
  • Diluent Partial Pressure of Oxygen Exceeds Safe Level
  • Diluent Partial Pressure of Oxygen Below Safe Level
  • Gas Time Exceeds Your Time Alarm Limit
  • Safety Stop Ceiling Broken by More Than 2 Feet
  • Tank Pressure Below Take Pressure Alarm Limit

Notifications are events that require preventative action. These will display in audio and visual alarms under Suunto EON Steel dive computer and can be acknowledged by pressing any button. The following are the notifications available on the EON Steel dive computer:

  • ​Central Nervous System Toxicity Level at 80%
  • 80% of Recommended Daily Limit for out
  • Change Gas: When Ascending on Multi-Gas Dives Indicates When It’s Safe to Change Gas
  • Low Battery: Approximately Three Hours of Dive Time Left
  • Recharge Needed: Approximately Two Hours of Battery Time Left
  • Setpoint Switched Automatically on the Rebreather Dive
  • Tank Pod Battery Life Low

With all the alarms and notifications available on the Suunto EON Steel dive computer it’s easy to see how this could be overwhelming for a new diver. All this information is great for the technical diver who may be diving repeatedly or using Trimix. However, for a new diver, this information is going to make them feel overwhelmed and unsafe. These alarms can be configured, but there are only four configurable alarms: depth, dive time, tank pressure, and gas time alarm. Each of those has their own limit and can be turned on or off.

Technical Capabilities

Suunto EON Steel uses the Suunto Fused RGBM algorithm. This algorithm does lock if you fail to complete a decompression stop longer than three minutes. This safety feature locks the algorithm if you ascend above the decompression ceiling by more than 2 ft. There are both an audible alarm and a visual alarm that will alert you to go back down below the decompression ceiling for you to complete your decompression stop.

Two different gas mixtures Nitrox and Trimix are compatible with the Suunto EON Steel dive computer. The compatible gases can be displayed in the following percentages: Helium %: 0–95 and Oxygen %: 5–99. When in Nitrox mode only the Oxygen percentage will be displayed.

Dive Log and Connectivity

Suunto has created their own mobile application that is available on both iOS and Android devices. The Movescount mobile app allows you to easily transfer your dives to the online log without the need for wires. The Bluetooth integration on the EON Steel is a great feature and one you would come to expect from a high-end dive computer like this.

Missing Functionality

There is no freediving mode on the Suunto EON Steel. The lack of a freediving feature is surprising considering how in depth Suunto’s programming is on this dive computer. The ability to turn off notifications would also be nice. The sheer abundance of alarms on this dive computer is a little cumbersome. Turning some of them off would be a great feature.

Features/Specifications

  • Multiple Gas Mixes
  • Bluetooth Connectivity
  • Rechargeable Battery
  • Three Bar Crush Depth
  • Mobile App Dive Log
  • 1000 Hour Onboard Dive Log
  • Multiple Audio and Visual Alarms
  • 150 m Maximum Depth
  • Built-In Thermometer
  • On Board Compass
  • Bright Display
  • Switching between gases

Pros and Cons

There’s a lot to like about the Suunto EON Steel dive computer. To begin with, the rechargeable battery is as good as gold. Having a rechargeable battery on a dive computer is pretty rare, so this feature stands out as one of the best. In addition to the awesome rechargeable battery, Bluetooth connectivity of the dive log makes syncing your dives to your mobile device easy and convenient. Finally, the large onboard dive log means that if you forget your mobile device or are on a long dive trip with no technology other than your dive computer you will not have to worry about losing dives.

Though there are a few things that aren’t that great about the EON Steel dive computer. It really is a very technical dive computer. This could be confusing for beginner divers and may be overwhelming. There are far too many alarms alerts and warnings that you cannot shut off. Not being able to customize all the different alarms alerts is really a low point for this dive computer. Finally, the Suunto EON Steel lacks a free diving mode. For all the bells and whistles that this computer has, you would think they would have included a free dive mode. Overlooking the simple feature that many low-end dive computers have seems to be a mistake on Suunto’s part.

Pros

  • Rechargeable Battery
  • Bluetooth Connectivity
  • Large Onboard Dive Log

Cons

  • May Be Too Technical for Beginners
  • Too Many Alarms
  • No Free Dive Mode

Conclusion

Overall the Suunto EON Steel is an excellent dive computer. For the price that you can find this dive computer for, it really does have a lot of great features. If you can get past the fact that this dive computer is going to alert you to everything that you might ever want or need to know about your dive, then this computer has a ton of great features.

All of the display items conveniently fit on one screen meaning that you don’t have to flip through screens to get all of your information. For those who want easy access to all their information, this dive computer is going to give you that and so much more. Suunto really packs a whole lot of information on to one screen with the EON Steel.

Who wouldn't like it?

People who prefer basic dive computers are not going to enjoy the Suunto EON Steel dive computer. Those who only want to be alerted to very vital information are going to dislike the mandatory alarms built-in to the Suunto EON Steel dive computer. The mandatory alarms that you can’t turn off along with the alerts and notifications can really be overwhelming to those who just want basic information.

Divers who are not very technical and don’t need tons of technical information are not going to enjoy this computer. It is designed for people who enjoy having all of the technical information at their fingertips during their dive. New divers especially are going to find that this dive computer by Suunto is voluminous and has entirely too much information for them to use.

Mares Puck Pro Plus Review

Review of the Mares Puck Pro Plus

This review is not a complete review as we have done it for the Mares Puck Pro. We opted instead to highlight the new features and commonalities between the Puck Pro and its successor, the Plus model

With most of the technical capabilities having stayed the same, we invite you to check out the in-depth review of the Mares Puck Pro to get detailed information on both diving computers.

Mares Puck Pro vs Puck Pro Plus

Mares introduced the Puck Pro Plus at the end of June. It slowly made its way into the online stores and can be ordered through Amazon and other online retailers by now.

Many divers asked what the differences between the Puck Pro and the Puck Pro Plus are. There are not enough (or many at all) that would make you dump your Puck Pro for the Plus model.

The first difference that is obvious is the slightly redesigned device itself. The bezel looks a little different. The bars for the N2 meter look different and the display segments have a clear labeling on the frame around the glass. Other than that, most of the colors are gone (for now) and you can get the Plus in black or black and white.

Navigation on the Puck Pro Plus and the Pro are handled through an intuitive single button. There’s no difference in the handling of both models besides the color change on the button itself. Both scuba diving computers are ready to have their firmware/software updated whenever Mares provides such an update.

The few optical changes mentioned above would not have justified Mares to change the naming and to introduce the Pro Plus as an evolution of the Pro. Let’s dive a little deeper to see what else has changed.

The technical specifications stayed the same. And that is a good thing. The Puck Pro offered the features you would want from an entry-level dive computer. The same is certainly to be said for the Puck Pro +.

The major news for the Pro Plus are that it can manage to connect to your smart phone or computer through a Bluetooth clip connector. There’s no more cables needed to download dive data to your phone, tablet or computer.

The Plus has seen more upgrades with regards to the connectivity and adaptability. The firmware can easily be updated, data exchange even with your smart phone is easy and straightforward.

Mares Puck Pro Plus Scuba Diving Computer with white bezel

Even the maintenance aspect has seen a positive change. The battery can easily be changed by you which saves a ton of money and time compared to having to send it in to an authorized dealer or service center.

Capabilities

The Mares Puck Pro Plus offers a sectioned, super-clear display. It’s segmented into three lines to display all require information on the oversized watch.

It can handle three dive modes:

  • Air
  • Nitrox
  • Gauge

It is capable to dealing with different gas mixes that you can switch between as needed. The Plus model can handle the switching of gas mixes during a dive with oxygen levels up to 99%.

Alarms can be set for the usual safety violations:

  • Ascent rate too high
  • Decompression stop ignored/missed
  • Battery low
  • High pPO2
  • High CNS (over 100%)​

Technical Specifications

There have been really no changes between the Pro+ and the Pro. The specifications stayed the same and are shown below:

  • Max. Depth of 150 m (492ft)
  • Onboard logbook size of 36 hours
  • Sampling rate is 5 seconds
  • Navigation through a single button
  • Crystal clear mineral glass (scratch and break resistant)
  • Various audio and visual alarms
  • Nitrox setting up to 99% oxygen
  • Switch between imperial and metric display
  • Easy to replace battery
  • Bluetooth connectivity through BLUELINK system

Where to Buy?

The Mares Puck Pro Plus is not that easy to be found online. Many online retailers specifically mention that it cannot be shipped outside the EU. If you’re in the US then your best bet on price and availability is Amazon. Click the button below to find the lowest price for the Mares Puck Pro Plus!

Conclusion

Mares will most likely slowly fade out the Puck Pro and replace it with the Puck Pro +. It’s nice to see this dive computer make its way into the modern era of ultimate connectivity.

Being able to transfer your dive data wirelessly to your smart phone is a big deal if you are on a dive vacation. There’s no need any longer to drag your computer along so that you can download the dive log before it gets overwritten. You can do that now through the Bluetooth interface and send the data to your phone.

That alone in our opinion justifies buying the Plus model. However, if you have the Pro now then there’s no reason to list it on eBay as long as you can live without the Bluetooth connectivity. If you purchase a new scuba computer and have your eye on the Puck Pro then go for the Puck Pro Plus instead if you can.

The updated design makes the diving computer overall look a little more grown up. The lack of colors will most likely be remedies by Mares over time but should also not be a reason why not to go for the Puck Pro Plus!

Aqua Lung Legend (LX, LUX, Glacia) Regulator Review

Aqua Lung is one of the best known brands with regards to any kind of scuba gear. They are known for their quality and innovative products. The Aqua Lung Legend LX and other regulators in the Legend series are no exception.

None of these regulators is on the cheap end of things but you can rely on getting a top-notch product if you get an Aqualung Legend regulator. They are made from high-quality materials and designed to last and to work.

Aqua Lung Legend LX

There are a number of different regulators available in the Legend series. The Legend LUX is the high end, flashy regulator. Flashy in the sense that the overall components are the same in the LUX as well as the LX but the LUX has a pink-gold/bronze looking finish. That finish will cost you a few hundred dollars more. The inner workings between the LX and LUX are pretty much the same.

On the lower end of the spectrum you can find the Legend itself. The main difference to the LX is that it uses a venture switch in the second stage to prevent freeflow at the surface. The LX and LUX use Aqua Lung’s own Master Breathing System (MBS) which use dual control valves to prevent the free flow of air.

Another model in the series is the LX Twilight which is basically the LX with a smaller mouthpiece. This is to make it a better fitting regulator for women. All of the above mentioned regulators also come as a ‘Supreme’ model. The Supreme regulators are specifically designed for cold water by adding a mouthpiece that surrounds your lips to keep them warm. All second stage regulators have heat exchange mechanisms built in to prevent them from freezing during a dive.

Lastly, there’s the Glacia model in the Legend series. This version is specifically designed for cold dives. It has additional heat exchangers in both the first and second stage to prevent the valves and chambers from freezing.

The closer look at the first and second stage components will show the differences between the models.

Aqualung Legend

First Stage

Aqua Lung uses a compact design on the first stage that packs a lot of technology. It’s available as either a DIN or Yoke design for all of the Legend models.

All first stage modules feature Aqua Lung’s Auto Closure Device (ACD). This device makes sure that there’s no water coming into the inlet when the first stage is removed from the cylinder valve. This prolongs the life of the first stage as it keeps water out which can cause corrosion or lubrication to be washed out.

The first stage uses an over-balanced diaphragm design. This allows for outstanding performance at depth. Breathing comfort is improved through that design as well.

The first stage is sealed so that water is kept out of the moving parts. This keeps it clean and extends its lifetime. It also greatly improves the ability to use the regulator in cold environments. Keeping the water out helps to prevent freezing.

All first stage regulators feature 2 high pressure and 4 medium-pressure ports. The ports are placed so they allow for optimal hose routing. Out of the box the first stage regulator is equipped to handle gas mixes up to 40% oxygen. That’s by any means enough for any recreational diver.

Aqualung Legend Glacia

Second Stage

The housing of the Legend second stage depends on the model. The lowest end, the Legend sports a polymer plate on a polymer casing. The LX similarly consists of a high-quality polymer casing with some chrome accents.

The LUX is basically the same second stage as the LX except that its finish is rose-golden and the surface is PVD coated. The coating is tough and will make the regulator look great for years to come. The Glacia is overall the LX with an aluminum front cover.

The breathing resistance can be adjusted on the LX, LUX and Glacia models. The Legend has a preset breathing resistance that cannot be changed.

The Supreme models of the Legend, the LX and the LUX as well as the Glacia offer a lip shield. This helps to keep your lips warm in really cold environments.

All second stage, as well as first stage, regulators of the Legend series come with built-in heat exchangers. These are allowing to dive in cold water with a much lower risk of freezing.

Technical Specifications

First Stage

  • Compact
  • Chrome plated brass (Legend, LX, Glacia), PVC Coating (LUX)
  • Over-balanced diaphragm design
  • Environmentally sealed
  • Ready for Nitrox mixes up to 40%
  • 2 high-pressure ports
  • 4 medium-pressure ports
  • DIN or yoke connectors

Second Stage

  • Pneumatically balanced
  • Breathing resistance adjustable (except for base Legend model)
  • Accented plate materials (aluminum for Glacia, all others polymer)
  • 2 Comfobite mouth pieces with bite wings
  • Heat exchangers to increase freezing resistance

Accessories and Options

Aqua Lung also designed a matching octopus regulator for the Legend series. The Legend Octopus is a great addition to your Legend regulator and guarantees a perfect match within your regulator setup.

Where to buy?

Usually you will find the lowest price for any regulator in the Legend series on Amazon.com. They have all different models available including the octopus regulators you might need.

All models come either with DIN or Yoke first stages. They are already environmentally sealed so there’s no need to having to look around for that option.

Aqua Lung Legend LX Twilight

Click here now to check the lowest price of the Legend LX Twilight on Amazon

Conclusion

The regulators in Aqua Lungs Legend series have an option for pretty much any diver. Whether you’re looking for an economic model like the Legend itself, a medium range design like the LX or a luxury version with the LUX, you’ll find a fit.

A woman should have a closer look at the Legend LX Twilight as the mouthpiece is smaller and will make it more comfortable to use. And if you are into extreme diving with really cold environments then have a look at the Glacia which is specifically designed to prevent freezing.

You end up with an excellent package no matter which regulator you pick. If at all possible you should try to skip the lower-end Legend as the LX and the models above it feature the Master Breathing System (MBS) from Aqua Lung which allows to adjust the breathing resistance. This will in the end help you to conserve air and allow for longer and more relaxing dives.

Mares Smart Dive Computer Review

Mares has designed and ideal introductory dive computer with their Smart dive watch. This dive computer has a lot of safety features built into it that are aimed at new divers which makes it a fun introductory dive watch. One of the best safety features that the Mares Smart dive watch has is the ascent rate lock out. This feature locks the dive computer for 24 hours if excessive Ascent rate has been maintained for more than two-thirds of the depth of the dive. This is set up to reduce the risk of expansion and nitrogen injuries.

Mares Smart in Black and Red

There are also alarms designed to keep you at your decompression stop as well as to make sure you don’t exceed your safe oxygen saturation. In addition to safety features, the Mares Smart dive computer has plenty of other features that will have divers easily navigating the waters. With a maximum depth of 492 feet or 150 m, this introductory dive computer is going to be good for a long time. You probably won’t outgrow this computer for many dives to come.


Review Summary

Experience Level

Has everything a beginner needs and doesn’t over complicate the diving computer system.

STYLE

It's sleek and has a slim profile compared to other wrist mounted dive computers. This could actually pass as a sports watch because of its slim profile.

Ease of Use

It can take a while to get where you want to go on the menus with only two buttons. What it lacks in navigation, it makes up for in display.

Price Level

It is a very low price point and perfect for beginners who aren’t sure whether or not they are going to keep this style of dive computer.

We Like

  • Lots of Safety Features
  • Audio and Visual Alarms That
  • Three Distinct Display Windows
  • Low Price Point
  • 150 M Maximum Depth

We Don't Like

  • Small Onboard Dive Log
  • No Air Integration
  • No Compass
  • Small Display

Summary:

Being an ideal beginners watch with plenty of safety features and a good maximum depth the Mares Smart wrist mounted dive computer has plenty of good points. The lack of air integration and compass can be overlooked when considering the small price point of the Mares Smart dive computer. You can easily get additional equipment that is more customized to the job because you didn’t spend it on a high-priced dive computer. This really is the perfect beginners diving computer

Mares Smart in Black and Grey

The Mares Smart features some sleek looks and has a slim profile compared to many other wrist mounted scuba diving computers. This could actually pass as a sports watch because of its slim profile. It’s available in multiple color options and has a nice design.

While the navigation with two buttons can be a little cumbersome at times, the display totally makes up for it. There are three distinct display windows dedicated to depth, safety stop, and miscellaneous information.

The Smart comes in a variety of color combinations:

  • Black
  • Black/White
  • Black/Red
  • Black/Grey
  • White/Lime
  • White/Lilac



Capabilities

The Smart is cleary designed as a beginner model. It's handling all the immediate needs of a beginner and mid-level diver and is useful as a daily watch.

It offers four different dive modes:

  • Watch
  • Air and Nitrox
  • Gauge
  • Free Diving
Mares Smart in White and Lime

The Mares Smart scuba computer has a lot of capabilities for a basic dive computer. To begin with, the maximum depth is 150 m or 492 feet making it ideal for those who would like to extend their diving knowledge to deeper dives. The Mares Smart is capable of nitrox mixes between 21% and 99% oxygen. You can have up to two gas mixes when using this dive computer.

If you are traveling a lot when you dive, altitude and decompression will be nothing that you need to worry about because the Mares has automatic altitude correction and decompression timing. Operating altitude with decompression is sea level to approximately 3700m/12100ft. The Operating Altitude without Decompression (gauge mode) is at any altitude.

One of the key features in the Mares Smart is the ascent rate exceeded lockout. There is an alarm that will go off that says to slow your ascent if you exceed the 10 m/minute ascent rate. However, if you reach 12 m/minute your Mares Smart will tell you both audio and visual to stop your ascent. Then if you exceeded the ascent rate of 12 m/m for over one-third the depth of your dive the computer locks for 24 hours to prevent dive injuries. It’s a pretty neat feature that not many others have.

In addition to the ascent rate alarm there are other audio and visual alarms available on the Mares safe dive computer including:

  • exceeding a safe ppO2
  • CNS =75%
  • missed decompression stop
  • low battery during the dive.

​All of these alarms help you stay safe when diving and are perfect for beginner divers.

Unfortunately, there is no air integration on the Mares Smart dive computer, so you will need an additional air gauge when diving with this computer. However, the low price point of this introductory dive computer makes buying an air gauge less of an inconvenience.

There is a wide temperature measurement range available on the Mares Smart dive computer. The temperature ranges from -10°C to 50°C (14°F to 122°F.) Anything outside of that range will compromise other readings given by the dive computer about depth and pressure. But considering that you will probably never dive in waters outside of that temperature range, you are safe to use the Mares Smart dive computer in any water.

The backlight is bright and easily seen on the Mares Smart dive computer, and it is also user adjustable. Adjusting the timing on the backlight allows you to save the battery life on the dive computer. The battery life has a range of 2 to 3 years. One of the major contributing factors in the battery life of the computer is the backlight. Limiting the time that the backlight displays is a great way to change how long your battery lasts. Once the battery does run out, you do have the ability to change the battery yourself without sending it in for pressure testing at the manufacturer or at a dive shop. This is a very useful feature, and many other dive computers do not feature at home battery changes.

Technical Capabilities

Mares doesn’t say which algorithms they use to calculate their altitude or decompression. Well, besides it being the Mares RGBM algorithm which is with regards to conservatism middle-of-the-road.

They have three settings they identify as the standard setting, intermediate setting, and conservative setting. These settings apply to both decompression and altitude.

Dive Log and Connectivity

Conflicting information is given by Mares on the on-board dive log for the Mares Smart dive computer. The User Manual states that the watch has 35 hours of dive profile at the 5-second sampling rate.

The Mares website says that the Smart’s on-board log is 20 hours, and a promotional video on the website says it is 25 dives. You should probably play it safe and download on to your computer log at 20-25 dives.

Missing Functionality

There are few features that we really wish were available on the Mares Smart diving  computer. The number one missing feature is air integration. Air integration would be a big selling point for this dive computer.

In addition to air integration, a compass would allow for easier navigation and one last piece of equipment to take on a dive. Integrating these two features would make this dive computer one of the best available on the market. Even without these two features, it is still a wonderful beginning level dive computer.

Features/Specifications

  • Free Diving
  • Nitrox Capable
  • Two Gases
  • Upgradable Firmware
  • User Replaceable Battery
  • 25 Hour Dive Log
  • Audio and Visual Alarms
  • 150 m Maximum Depth
  • Battery Power Indicator
  • Dive Plan Mode
  • Gas Switching
  • Altitude Adjustments
  • Daily Alarm
  • Segmented Display
  • Bottom Timer
  • Automatic Safety Stop

Pros and Cons

The best part about this watch is the price point. You can’t get a better-priced diving watch that has the same amount of features as the Mares Smart scuba computer. Also, it is easily used and navigated by beginners and not overly complicated. The segmented display allows you to easily see the information you need without having to navigate through menus to find what you’re looking for.

Not having air integration or a compass can be a big drawback for some divers. More experienced divers may find that this watch lacks simple things that they’re used to having like bar graph displays. The display is rather small so if you need large prints or have visual impairments this dive computer by Mares may not be the best option for you.

Pros

  • Price
  • Segmented Display
  • Maximum Depth
  • Easy to Use
  • Audiovisual Alarms

Cons

  • No Air Integration
  • No Compass
  • Only two gas mixes
  • Limited Display information
  • Small Display

Conclusion

While the Mares Smart computer is not going to please everyone, it is definitely the perfect introductory dive computer. Beginning divers are not going to be overwhelmed by tons of information that they don’t need or don’t know how to use. The three-segmented display on the computer as well as the two buttons allow new divers to get a good sense of the information that they need to have each dive.

The dive plan mode is simple to use, and the automatic sensor for dives and timers will automatically track dives even if you forget to start or plan a dive. The audio and visual alarms will allow new divers to easily track and see their bottom time ascent rate and safety stop information. It is a wonderful computer for getting all the essential diving information to the diver without cluttering up the screen with non-essential graphs and displays.

Who wouldn't like it?

If you’ve been diving for a long time and our technical diver you probably want more information from a dive computer than this has the ability to offer. Things like air integration GPS and compass navigation are all unavailable in the Mares Smart basic diving computer, so you probably will be unsatisfied purchasing this basic dive computer.

In addition to technical divers, people with visual problems who need larger displays or color displays may have a problem seeing the small screen on the Mares Smart diving computer. This is not recommended for people who are used to larger displays on the computer style or touch screen style dive computers.

If you’re a data junkie and just want to know everything about what’s going on with every piece of equipment and you want it all to filter through your computer, don’t get a Mares Smart. This device is designed to give basic diving information that is necessary for you to know your bottom time, your ascent rate, and your overall diving stats. It’s a great dive watch and computer but not for someone looking for something with a lot of bells and whistles.

Ninja H2O vs. Tribord Easybreath

Comparing the Tribord Easybreath and Ninja H2O Full-Face Snorkel Masks

Both the Tribord Easybreath as well as the Ninja H2O are full-face snorkel masks. And on top of that they are two of the best of these kinds of masks you can get.

There are some noteworthy differences though that you should be aware of. And they are not only functional.

The advantage of the Ninja mask is that there is a variant that has a GoPro mount. The Easybreath has no such feature which means that you will have to hold the camera in your hand while you snorkel.

The Tribord Easybreath in Blue.

Otherwise, both masks look very similar. They are both available in a number of different colors which makes it more fun to use and wear them.

History of the Full-Face Snorkel Mask

The Tribord was the initial full-face snorkel mask. Many other masks imitated the basic design but not many are able to reach the quality and features of it.

The major accomplishments of the Easybreath design were the panoramic view, the ability to breathe through mouth or nose, the compact design with an integrated dry snorkel and the bright tip of the snorkel for safety.

Additionally, the designers packed a nifty system into the mask to prevent it from fogging up. And they have done a great job which many of the masks since then were not able to replicate.

H2O Ninja Full Face Snorkel Mask

The Ninja H2O is in many aspects as good as the Easybreath. Yet, the big difference is that it unfortunately costs quite a bit more. And we can’t really figure out why you’d pay so much more just for having a GoPro mount added. In that case you’re better off with the Seaview 180 Degree which offers the same for a more reasonable price.

Tribord Easybreath vs. H2O Ninja

Both are very comparable masks made from highest quality materials. They sit comfortably and are easy to adjust and use.

The Easybreath has a somewhat better system to prevent fogging. On the other hand, the Ninja H2O offers the GoPro mount. Depending on your needs this can be a big selling point.

However, if you don’t have a GoPro then it’s a moot point to have the mount and at that time it comes down to the Tribord design being superior.

A potentially huge difference is that you get a lot of different sizes for the Easybreath while the H2O only comes in two different sizes. If you’re looking for a mask for your children then it’s more than likely that you will not find a good fitting Ninja mask. You will most likely find a good fit with the Tribord model!

Having a bright tip on the snorkel can be very important in crowded areas. It makes it easy to be seen from the many water enthusiasts that are on the water like for example surfers. The Ninja mask unfortunately does not offer a brightly colored tip and as such the Easybreath clearly is the winner when it comes to that safety feature.

Conclusion

The Ninja H2O is a well-made mask. It has a solid design and uses top quality material. Similar as what you get from the Easybreath.

The biggest advantage of the Ninja mask is that you get the GoPro mount. Yet, the Tribord scores on many (if not all) other important aspects.

It has a better system to prevent fogging, offers a bright snorkel tip to make it safer for you in the water, and it is cheaper.

If you need the GoPro mount then you might want to have a look at the Seaview 180 Degree mask. It offers similar quality as the Easybreath yet has a GoPro mount. The cost of the Seaview is similar to the Tribord mask which makes them quite a bit cheaper than the H2O!

You will not be disappointed if you go for either of these masks. They both do their job and they do it well. The winner in many aspects is the Easybreath and it’s also our recommendation. You will enjoy your snorkeling trips as they are elevated to a new level.

Oceanic OCi Dive Computer Review

This wrist watch style dive computer by Oceanic is great for new and experienced divers alike. The Oceanic OCi dive computer is a wristwatch style computer. It features 4 buttons that allow you convenient on-screen navigation. The display is large enough to be seen under water, and the backlight works well at depth to illuminate the display. Some may find the display is a little too small compared to the larger touch-screen style dive computers.

The optional wireless air integration makes this an excellent moderately priced dive computer. The wireless air integration limits the hoses that you will have surrounding you making your dive seem less cumbersome. With 4 air mixes and nitrox optional, this dive computer allows even those who prefer deeper dives or higher percentages of oxygen to utilize a moderately priced dive computer.

Summary:

The Oceanic OCi scuba diving computer is a fantastic midpoint dive watch. It comes with almost everything that you would need including air integration and battery hot-swap. Though the watch may be a little bit bulky for small framed people, it can be worn everyday for those who prefer to wear only one watch for all purposes. This makes it very convenient when tracking altitude and flight times.

If you’re looking for a watch with a large memory, the OCi is not going to be the watch for you. It only stores 24 dives at a time before you need to upload your dives into your dive log. A long diving trip may require that you download your dives while still on the boat.

Altogether this device is perfect for the average diver. New divers are going to find that this has more features than they will probably use. More experienced divers are going to see that this watch by Oceanic has everything that they need. If you require an LCD screen or larger display you may want to look at a higher pricepoint watch.

Oceanic OCi in titanium color

While we overall like that a dive computer can be worn as a wrist watch, in this case we're not certain about it. The device offers so much functionality that it feels like a large screen would be beneficial.

However, the display is easy to read and clearly setup. The navigation is performed through four buttons and it's easy and intuitive to step through the menu choices to get where you want to be.

The OCi comes in a variety of color choices:

  • Black
  • White
  • Black/Red
  • Black/Yellow
  • Black/Titanium
  • Black/Blue



Capabilities

When looking at the Oceanic OCi, you’re going to find it has many features. Oceanic claims that the “I” stands for incredible. That’s not far from the truth considering the pricepoint for the watch and the features that are available.

It offers four different dive modes:

  • Watch
  • Norm (Air and Nitrox)
  • Gauge
  • Free Diving
  • Tech Free Dive

​You can activate the watch with the push of a button or use the water activation system included on the watch.

The maximum depth for the Oceanic OCi dive computer is 180 m or 495 ft when working in the gauge or free dive mode. When working in the normal operating mode, the maximum depth is 330 ft or 100 m. There is a deep stop with countdown timer allowing you to see your multiple safety stop times without difficulty. The optional two countdown timer for deep dives is half maximum depth for dives 80 feet or greater.

There is both temperature display as well as compass included on the Oceanic OCi dive computer. The other displays include air time remaining, nitrogen tissue loading bar graph, oxygen loading bar graph, no decompression time remaining, air time remaining, and O2 times. This allows you to customize your display to your personal preference.

The backlight on the Oceanic OCi is automatic and uses the OceanicGlo backlight technology. The time that the backlight is on is adjustable by the user. This allows you to maximize the life of the battery by limiting the backlight time.

The OCi dive computer uses the CR2450 battery, and the transmitter uses a 3.6V CR2 battery. The battery life for the dive computer is 300 hours, and the transmitter has a battery life of 1500 hrs. Hot-swap is available on the Oceanic OCi dive computer allowing you to retain all dives when changing the battery. There is a low battery indicator, which is a graphic display on the dive watch. The only downside to the battery options on the Oceanic OCi dive computer is that the manufacturer recommends pressure testing by either the dealer or the factory when replacing the battery.

There are several alarms available on the Oceanic OCi dive computer. You can set:

  • dive time remaining
  • maximum PO2
  • free dive elapsed dive time
  • free dive countdown timer

There are also high O2 and high PO2 alarms as well as your normal alarm clock and safety stop alarms.

The Oceanic OCi dive computer allows you to display time in either 12 or 24-hour format. There is a calendar available on board as well as the 24-hour time to fly countdown. This easily allows you to track dates and times, especially when tracking flight information.

Technical Capabilities

Oceanic uses exclusive dual algorithm technology to power the OCi dive watch. You can choose between the Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis) algorithms to get the most out of your dive.

The OCi dive computer has the capability to switch between four nitrox mixes. The mixes can go from 21 to 100% O2. The wireless transmitter has the capability to switch between four independent transmitters for the difference O2 mixes allowing you to easily swap tanks and dive without changing the settings on your transmitter or computer.

There is automatic altitude adjustments featured on the Oceanic OCi dive computer. The altitude algorithm basis is NOAA, as well as the O2 limit basis. The automatic altitude adjustment is 610 to 4200 m allowing you to rely on your Oceanic to safely prompt you for flight countdown and altitude adjustments.

Dive Log and Connectivity

The on-unit dive log of the Oceanic OCi dive computer has the capacity to hold 24 dives. Included with the dive computer is the Oceanic log computer PC or Mac download and upload settings.

The Oceanic download memory capacity is 1 MB total. You can connect your Oceanic dive computer to your Mac or PC with a USB cable.

Missing Functionality

The biggest feature that is missing from the Oceanic OCi dive computer is the lack of an ascent rate exceeded alarm. In addition to that, we also wish that the battery was user replaceable on this dive computer. Having to take the computer to a dive shop to be pressure tested to change the computer can be a hassle.

Pros and Cons

There is a lot to like about the Oceanic OCi dive computer because it has a ton of features in a small package. For those who don’t like a lot of bulk on their diving gear but want a lot of features in their dive computer, this is going to be the ideal moderately priced dive computer.

Conclusion

If you’re looking for a moderately priced dive computer that has everything you need to plan a dive, then the Oceanic OCi dive computer is going to be exactly what you need. It has all of the features you would expect from a more expensive watch like wireless air integration and battery hot-swap. But it doesn’t take up too much room because it still maintains the watch style wrist mount.

For being such a small dive computer, it has plenty of features. New divers are going to have everything they need and more. Experienced divers will probably find that this dive watch has everything they want. The multiple settings and display options allow you to program different dive settings for various dive environments. Making it easy for you to dive multiple locations without reprogramming your watch.

People who do not want to spend a ton of money for wireless air integration are going to really enjoy the Oceanic OCi dive computer because you can get a lot of features without spending a lot of money. The computer doesn’t take up a ton of space on your wrists, so it minimizes the bulk you carry around with you at depth. For the minimalist diver, this dive computer is going to be perfect.

Who wouldn't like it?

If you like to be able to view bar graphs and displays while underwater this watch is not for you. Those people who need larger LCD or OLED displays to be able to view their time at depth will dislike the small display on the screen. The four-button system can be frustrating for those who are used to touchscreen interfaces.

More technical divers may find that this computer lacks the appropriate displays they need or want. Without being able to display everything at the same time, like you would be able to do on a larger dive computer, technical divers may find that they just want a little bit more from the Oceanic OCi scuba computer. But for the pricepoint, it is exactly where it needs to be both in functionality and design.

Atomic Aquatics Z3 Regulator Review

Atomic Aquatics are known for the top-of-the-line quality and technology when it comes to dive gear. This reputation is reflected in all their equipment including their regulators like the Atomic Aquatics Z3 Regulator.

Yet, they are also known for these features and design to come at a premium price. However, the Z3 is a relatively affordable high-end product with no compromises in quality.

Atomic Aquatics Z3 Regulator with Yoke

All Atomic Aquatics regulators leverage the same principles in their design. Combining top-quality materials with solid construction to produce long-lasting regulators that work and that have low maintenance requirements.

The Z3’s lower price point is due to using materials that are high-quality but not quite as top-of-the-line as what they use in their highest-end regulators. This design features for example the use of a specific plating process where a layer of Zirconium (hence the ‘Z’ designation) is on top of a chrome layer on brass. This increases the resistance to corrosion by a factor of 3 to 4 resulting in a long-lasting design with low maintenance.

While not as high-end as the titanium used on their top regulators, it’s a great compromise to achieve a long-lasting regulator at a reasonable price. It will outlast many of the competitor products while not completely reaching the performance levels of the titanium designs. Yet, for nearly all recreational divers this is a more than satisfying design and material choice!

Check out what you need to know about regulators in our Buying Guide for Regulators!​

Let’s have a detailed look at the components of this regulator in the following sections.

First Stage

The first stage is a compact design using chrome plated brass and stainless steel as the materials of choice. It uses Atomics’ Jet Seat high-flow piston design to provide the diver with a natural breathing experience.

The Jet Seat system is unique to Atomic. There are no sharp edges used for the piston design increasing the durability and reducing any maintenance needs. The piston is also self-lubricating providing a practically friction-free design to further reduce maintenance requirements. This design in combination with the high-quality materials increases the maintenance interval to 2 years or 300 dives (whichever is first).

The first stage can also optionally be purchased being factory sealed. This keeps silt, sand and other contaminants out and prevents mechanical failures. It also improves the capabilities of the regulator to not freeze in cold conditions. You can get the first stage either as a DIN or Yoke design depending on your needs!

Atomic Aquatics Z3 Regulator with DIN

The Z3 offers two high-pressure ports and seven low-pressure ports on a fixed cap. More than enough ports to connect all kinds of gear requiring pressurized gas. It is compatible for Nitrox diving with mixes of up to 40%.

Second Stage

The second stage of the Z3 consists of a housing crafted from high-grade polymers. The internal components are made from zirconium and chrome plated brass and titanium elements. This material mix offers a long-lasting, corrosion-resistant second stage.

Atomic also included their seat-saving orifice. The valve is lifted away from its seat when the regulator is not used. The result is that the pieces don’t get fused during the periods where you don’t use it and that leads to prolonged usage and life of the gear.

Compared to the predecessor, the Z2, Atomic added a swivel connector to the regulator. This allows the hose to move up to a 30 degree angle reducing the pull on the regulator. The swivel has a specific PVD coating which prevents scratches that in turn could prevent movement. It’s a lot more comfortable to wear and use.

The second stage also comes with a single adjustment knob. It allows to rapidly de-tune the valve if necessary. It is designed to provide a balanced linear flow to make breathing comfortable and effortless in all conditions and depths. The Z3 has a high-flow case which is designed to optimize the breathing effort irrelevant of the depth.

The front cover is made from two different materials and comes in a variety of colors. The entire front plate of the second stage of the Z3 is used to purge it if needed. The mouthpiece is made from different silicone elements with bite tabs made from harder material to prevent wear and tear such as biting through it.

Most divers will travel with their regulator and it is strongly advised to get a regulator bag to keep your gear safe. The Atomic Aquatics Deluxe Regulator bag is the perfect storage and travel companion to make sure your Z3 regulator stays safe.

Where to buy?

You will usually find the lowest price for the Atomic Z3 on Amazon.com. They typically also have the widest selection of colors available.

The first stage is available as either a DIN or a yoke design. You can also get them sealed which prevents outside contamination.

Conclusion

If you’re looking for superior design combined with a solid material mix and a reasonable price then the Atomic Aquatics Z3 regulator is what you’re looking for. It offers all the design features you get with the (way) more expensive T3.

The difference being that the T3 uses titanium throughout which reduces the weight and is practically corrosion free. If you can live with a little more weight and a bit more maintenance to prevent corrosion then the Z3 is the way to go.

You get the famed Atomic Aquatics design and quality in an affordable package without compromises. The regulator comes with a limited lifetime warranty and requires service only every two-years or 300 dives which significantly lowers your maintenance costs!
