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.


Review Summary

Experience Level

Has everything a new diver needs and everything an experienced diver wants.

STYLE

Watch sized to be worn all the time yet a little bulky if you have a small wrist.

Ease of Use

Navigation through four buttons.

Price Level

Moderately priced. Optional wireless integration adds to price if required.

We Like

  • Can be worn as an everyday watch
  • Hot battery swap, retains data
  • Air integration optional
  • Dual algorithm
  • 4 air mixes

We Don't Like

  • Battery replacement needs pressure testing by dealer or factory
  • Small digital display
  • Small log book contains only 24 dives

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.

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
Oceanic OCi in black and blue

​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.

Features/Specifications

  • Four Operating Modes
  • Four Pushbuttons for Navigation
  • Watch sized display showing all data required in one view
  • Wrist Mounted
  • Water or Pushbutton Activation
  • Dual Algorithm
  • NOAA Altitude and O2 Basis
  • Automatic Altitude Adjustment
  • Multiple Deep Stop
  • Automatic Safety Stop Prompt
  • Wireless Air Integration
  • Audible Alarms
  • Backlight
  • Temperature Display
  • Compass
  • Countdown to Flight Timer
  • 24 Dive Onboard Log
  • Three Optional Display Settings
  • Free Dive Options
  • Limited warranty of 2 years

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. While it is missing a user replaced battery, that can be easily overlooked when you consider all the other features that are included in this dive computer.

Pros

  • Multiple Display Options
  • Multiple Alarm Options
  • Sleek Style
  • Automatic Activation
  • Dual Algorithms
  • Four gas mixes
  • Altitude Adjustments fully automatic

Cons

  • Small Display
  • Battery requires pressure testing when swapped
  • Small onboard dive log
  • Bulky when worn as a regular watch

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.

Oceanic Geo 2.0 Dive Computer Review

The Oceanic Geo 2.0 dive computer is a neatly designed device that you can wear as a watch every day. It’s made with the beginner to mid-range recreational diver in mind and has the dual-algorithm that Oceanic is known for.

The price reflects the market it targets and so do the features. You won’t find any features you’d expect from a high-end scuba diving computer like air integration, etc. For the range and market it targets, it is a great device and fulfills the requirements you have.

Oceanic Geo 2.0 in Titanium with slate blue ring

Review Summary

Experience Level

Targeting the beginner to mid-level recreational diver.

STYLE

Wrist dive computer sized as a watch.

Ease of Use

Four buttons along the outside making it easy to use even with gloves.

Price Level

Fairly priced for the features offered.

We Like

  • Clear display making it easy to read
  • Straightforward navigation with four buttons
  • Good set of features
  • Dual algorithm

We Don't Like

  • No air integration
  • Graphs on screen are too small
  • Small logbook for only 24 dives

Summary:

The Oceanic Geo 2.0 is a great scuba computer for beginners and medium experiences/mid-level recreational divers. It offers a lot of features you expect from a device in that range. One of the best certainly being that it supports two different algorithms. Yet, it also has some downsides as the log book is rather small and there’s no ability for air integration. The logbook issue is easily overcome by offloading the data to a computer and the missing air integration is really not surprising considering the price point.

Oceanic Geo2.0 in white and slate blue

The display is somewhat cramped yet easy to read and understand. The four buttons to navigate through the menus are nicely spaced and intuitively allow to go from menu item to menu item.

The Geo 2.0 is available in four different color combinations:

  • Titanium/Slate Blue
  • Titanium/White
  • White/Slate Blue
  • White/Sea Blue

It is worn at the wrist and it is sized so you can use it as an everyday watch. This makes it a great investment as you get more out of the device. However, it also reduces the screen size and that can in dark and murky waters cause a little trouble to read the information. It’s overall a question of personal style.




Capabilities

The limited real estate on the screen results in the important data being somewhat smaller compared to large sized devices. This is compensated through the fact that you can wear the Geo all day long and every day. The important information is showing on the screen so there’s not much navigating through different screens needed when you’re under water.

Geo 2.0 by Oceanic in Titanium and White

It offers four different dive modes:

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

The Geo only comes as a wrist scuba computer. Oceanic offers no console variant of it. If you want a low cost console computer from Oceanic then you have to look at the VEO 2.0. It offers less capabilities but is designed as a console device.

The screen shows all important data like depth, time, temperature without having to scroll through any menus. All data is available at a glance yet due to the smaller screen size it can at times take a second to be able to clearly read it when you’re in somewhat darker environments.

It is designed as a entry-level to mid-range scuba computer and does not offer high-end capabilities like air integration, compass, etc. The display offers a low battery indicator reminding you to replace the battery before going down on a dive.

One of the really nice advantages is that you can change the battery yourself. This otherwise can be a real hassle when you have to send it in to a service center. Being able to replace the battery yourself saves you money and time.

It’s easy to master the navigation on this device. Two buttons are used to step forward/back in the menu tree and to select a specific setting. One button is used to save a setting while the fourth button is there to switch on the backlight. It’ll only take you a few minutes to get used to the navigation. The buttons are spaced out far enough to ensure that you press the right button even with gloves.

The Oceanic Geo 2.0 has the necessary audible and visual alarms that you’d expect and which differ based on the operational modes. For air or nitrox diving the alarms you can set are:

  • Dive Time exceeded
  • Too fast ascent
  • Max. Depth violation
  • PO2 limit violation
  • Decompression violation
  • Gas switch would expose diver to PO2 > 1.6
  • Violation of deep stop

Technical Capabilities

The Geo 2.0 can handle two gas mixes with up to 100% oxygen levels. You can set the pO2 limits to be between 1.2 and 1.6 bar.

The maximum operational depth for Air/Nitrox diving is 100 m (328 ft) and for Gauge it is 120 m (393 ft). It also has altitude adjustments that it selects automatically based on your altitude before a dive. The maximum altitude that can be handled is 4,270 m (14,000 ft).

The algorithm is where all Oceanic personal scuba computers shine. They offer dual algorithms allowing to switch between them at will. This is a great feature if you dive with a buddy that has his own computer which calculates based on a specific model. You at least will be able to somewhat get the calculations in sync!

The algorithm you can select is either the Buhlmann ZHL-16c based PZ+ or a DSAT based model. The DSAT variant is better suited when you want to pick a liberal recreational dive algorithm. The Buhlmann algorithm is more conservative. You also can adjust the conservatism of either of the calculation models by yourself to achieve a more conservative dive profile.

When used as a daily watch you can set the Time mode. All background calculations and measurements will be stopped and you can use the Geo 2.0 like a standard wrist watch.

Dive Log and Connectivity

The dive log is somewhat limited. You can save dive data for up to 24 dives. Data sampling can be set to either happen at 2, 15, 30 or 60 second intervals.

You can transfer the data from your dives to your computer. There is an optional connector required and you can then analyze your dive data on your computer to review dives and/or plan future dives. The Geo 2.0 also has a quick select of the last dive so you get a fast view on the data without having to search through the menu.

Missing Functionality

Being an entry-level to mid-range diver computer, the Oceanic Geo 2.0 is certainly missing some features. You don’t get air integration and no built-in compass. This are features you can get and expect from higher-end devices which then also cost you a lot more money.

Features/Specifications

  • Easy to navigate with 4 buttons
  • A range of audible and visual alarms
  • Watch sized display showing all data required in one view
  • Four operational modes for Watch, Air/Nitrox, Gauge and Free Diving
  • Two gas mixes between 21% and 100%
  • PO2 limits adjustable from 1.2 to 1.6 bars
  • Two different algorithms with additional conservatism settings
  • Max. operating depth 100 meters/328 feet for Air/Nitrox and 120 meters/393 feet for Gauge
  • Automatic altitude adjustments up to 4,270 m (14,000 ft)
  • Selection of imperial or metric mode
  • Dive log with capacity for 24 dives
  • Log sampling rates selectable at 2, 15, 30 and 60 seconds
  • User switchable battery
  • Four different color combinations
  • Limited warranty of 2 years

Pros and Cons

There’s not much you’ll be missing with regards to features when you compare the Oceanic Geo 2.0 with other scuba computers in the same category. You won’t be able to grow the capabilities of this device over time as you can’t add for example air integration. However, you do get a solid diving computer with a complete set of features that satisfy the needs of beginner and recreational divers.

The highlight of the Geo 2.0, as for all Oceanic dive computers, is that they offer two different algorithms. This allows you to pick a more liberal or conservative calculation model while you additionally can adjust the conservatism settings for the algorithm that you picked.

Pros

  • Easy to learn and use navigation with 4 buttons
  • Dual algorithms with additional conservatism settings
  • Four different operation modes (Watch, Air/Nitrox, Gauge and Freedive)
  • Two gas mixes
  • Ability to switch gases during dive
  • Automatic altitude adjustments
  • The capabilities you need as a beginner or mid-level recreational diver

Cons

  • Limited screen real-estate as it is sized as a wrist watch
  • Logbook on the smaller side
  • No possibility for air-integration

If you are a beginner of mid-level diver then this is without a doubt a great dive computer. It offers the right set of features you will need and some more. If you require more sophisticated features like air integration then this is not the right device for you.

Customer Feedback

Overwhelmingly, you only find great reviews online. Divers that bought this device are happy. Most anyone is impressed with the features offered and specifically being able to select between two different algorithms. This helps tremendously if your dive buddy uses a different brand as you can pick an algorithm that nearly matches your buddy’s. This way you don’t have to constantly wonder whether his or your alarms going off are the right ones!

Conclusion

The Oceanic Geo 2.0 is a great scuba dive computer for a recreational diver that wants to also use it as a daily watch. It’s fully featured to satisfy the needs of a beginner to mid-level diver and is priced right.

Being sized as a wrist watch reduces the available screen size. It’s still capable to display all important information in one screen but the data is not displayed as large as it is on an oversized version. Displaying any data as a bar graph definitely shows the limits of the small screen.

It is amazing that Oceanic packed their dual algorithm technology into such a convenient and small device. There was and is no compromising on this end and on safety features due to the size.

Whom is it not for?

You’ll have to look upwards when looking for additional features. These will cost a bunch more and you will have to ask yourself whether you truly need those features. For most divers it’s perfectly fine to have a console with a pressure gauge and a compass in addition to a wrist scuba diving computer.

If you do require those higher end features then have a look at the Oceanic OCi that offers everything you need. Alternatively, you can then also check the Suunto Vyper Novo which also offers a complete set of features at a reasonable price.

Cressi Goa Dive Computer Review

Cressi introduced the new Goa dive computer earlier this year. It’s a wrist watch sized device that comes packed with functionality.

It’s not available yet in the US so we evaluated the technical specs as they are available at this time. Based on that information it seems like you’re looking at similar features as in a Cressi Leonardo that is sized as a watch that you can wear every day.


Review Summary of the Cressi Goa Dive Computer

Experience Level

For the beginner and recreational diver.

STYLE

Wrist watch sized to be worn every day.

Ease of Use

Simple two button navigation allowing quick menu access.

Price Level

Reasonably priced for the features it offers.

We Like

  • Can be worn as a day-to-day watch
  • Large numbers on display for quick reading
  • Large number of dive modes
  • Can be completely reset

We Don't Like

  • No air integration capability
  • No built-in digital compass

Summary:

Based on what is known at this time as well as assuming that most of the features match the Leonardo, you’ll be looking at a great dive computer for beginners and recreational divers. Many divers never require the missing features like air integration or a compass and as such this might just end up being the only one you ever get.

Cressi Goa Dive Computer Black and Blue

The Cressi Goa is available in a number of color combinations: black, black/grey, black/blue, white/pink and white/grey. You'll be able to find a stylish color combo that you can wear every day.




Capabilities

The Cressi Goa supports the following dive modes:

  • Air
  • Nitrox
  • Gauge
  • Free Dive
  • Off Mode
Cressi Goa Scuba Computer White and Pink

The Cressi Goa has a diameter of only 48 mm making it a great size to use and wear as an everyday watch. It features a high contrast display with large numbers to make it easy to read under any circumstance.

As you would expect, the display is backlit for dark environments. The time can display in 12/24 time format and it has a calendar function.

Navigation on the Goa is managed through two buttons on the side. The navigation is easy and straightforward.

The Goa offers a number of alarms that are both visual as also audible:

  • ​Breach of ascent speed
  • Decompression ceiling violation
  • pO2 limit violation
  • Low battery

A great feature included in the Goa, similar to the Leonardo, is that the computer can be completely reset. This makes it a perfect device for dive shops as they are able to perform the reset between different divers. At that moment no dive history is in the memory anymore and the calculations for decompression, etc. start from zero.

Technical Capabilities

The Cressi Goa can handle Air and Nitrox diving. You can switch between nitrox and air during desaturation.

The operational max. depth is 120 meters/393 feet. Additionally, the Goa provides altitude adjustments. It also includes no fly time calculations as well as a surf time and a desaturation calculator.

The algorithm used is Cressi’s RGBM. It can be adjusted for different conservatism settings. Cressi’s algorithm has a long history and is proven to be safe and sound.

Dive Log and Connectivity

The dive log is reasonably large. You can keep dive data for the last 50 dives for each category. So, you can save 50 air dives, 50 nitrox dives, etc. That’s plenty of capacity to store data on the dive computer itself.

Missing Functionality

If you are a beginner or a recreational diver without the need for multiple gases then this could very well be the dive computer for you. If you are already considering switching to technical diving then this will not be the right device for you.

It’s not to be expected to have air integration for a dive computer in this category. It is also not necessary to have it. It’s pushing the price point up a lot to have wireless air integration and it quickly becomes uneconomical for most divers.

A built-in compass is also a nice-to-have feature that is missing. However, assuming you have a console with a compass and a pressure gauge does already take care of both of the missing features for the Cressi Goa.

Features/Specifications

  • Two button navigation
  • Air/Nitrox capable
  • Five different dive modes (air, nitrox, gauge, free diving, off)
  • Cressi RGBM algorithm with adjustments for additional conservatism settings
  • Maximum operational depth of 120 meters/393 feet
  • Cressi RGBM algorithm based on a modified Haldne and Wienke model
  • Maximum depth display to 120 meters/393 feet
  • Data displayed in either metric or imperial units
  • Dive log of up to 50 dives for each mode
  • You can change the battery yourself
Cessi Goa Dive Computer Black

Pros and Cons

The Goa does have the features you’d expect from a recreational dive computer. Judging the features based on the Leonardo, you’ll be able to get a great dive computer for the money. In the case of the Goa you even get more features in a smaller package for some more money.

Pros

  • Simple dual button navigation
  • Small size, can be worn as a daily watch
  • Cressi RGBM algorithm with conservatism settings
  • Different Dive Modes(air, nitrox, gauge, freediving and off)
  • Complete reset capability

Cons

  • No air integration
  • No compass

Assuming that the features match at least the functionality that the Leonardo provides, then you can take it that this is a great dive computer. The couple of missing features are nothing you'll be missing in a scuba computer in that price range.

Where to Buy?

The Goa is not yet available. As with any purchases you will usually get the lowest price on Amazon. In addition to the best pricing you also typically have the widest selection of different colors on there.

Another advantage of Amazon is that you can get free two-day shipping if you are a Prime member. It’s also easy to return or exchange products if they’re not what you expected or if they’re not working.

Conclusion

Expecting the Cressi Goa to be a dive computer with more features than the Leonardo yet all packed into a smaller package makes us believe that it’ll be a great device to have. Based on the technical data you can expect a lot of functionality in a small device for a great price. We’ll be updating this review with further details once they get available and we’re able to verify the claims.

Whom is the CRESSI Goa not for?

​If you are into technical diving then you will need features that the Goa doesn't offer. You might want to consider looking at the Suunto Vyper Novo in that case as a great choice.

Best Dive Computer under $500

Finding the best dive computer under $500 should not be a challenge. That is if you are looking for a DC for recreational diving. Don’t expect to get a device that has features that you’ll need for technical diving.

We cover what you can expect from a device at that price point and what you won’t get. Lastly, we showcase three dive computers that stay under the $500 mark.

Mares Smart Wrist Dive Computer

What Features can you expect?

At this price point you’ll get the basics. You can expect a reliable device that will keep you safe during a dive.

Regarding specific features you can expect the following:

RGBM with Adjustments

A safe RGBM algorithm that continuously calculates your dive data to keep your dive within healthy limits. Pretty much each dive computer manufacturer has their own variation of a RGBM algorithm.

Some are more conservative than others. If you dive with a buddy that has a DC from a different brand then you have to expect your dive limit calculations to be different!

Most algorithms also offer the ability to change the conservatism of the calculations. The settings allow to change the limits within the algorithm to be more conservative which ultimately means they end up providing you a larger safety margin.

One or Multiple Gas Mixes

Most dive computers in this price range will provide the ability to have one nitrox mix. Usually they support oxygen levels up to 50%.

For most beginners and recreational divers being able to manage one gas mix is good enough. If you’re relatively new to the sport then diving with a single gas mix will cover you for usually the first few years if not even for a lifetime.

You find more and more dive computers that can handle up to two gas mixes. Most newer models are capable to do that. Depending on your dive needs this might or might not be an important feature for you. For recreational diving it often is of less importance to have this feature.

Audible and Visual Alarms

All dive computers in this price range offer various audible and visual alarms. Typically, you can expect the following types of alarms to be setup for a dive:

  • Dive Time​
  • High pO2
  • Violation of decompression ceiling
  • Maximum depth violation
  • Ascent too fast

These are the alarms that are most important for a recreational diver and they are usually all covered by a DC at this price point.

Dive Log

You should expect the DC to have a solid dive log with enough memory to store dive data for at least 20 dives. Some models even provide enough capacity for over 100 hours of dive data to be collected.

Usually, the dive data will be collected at a fixed rate. Some models will allow to adjust the collection rate.

Connectivity to Computer (optional)

Dive computers offering a dive log will also offer the (optional) ability to connect the DC to your computer. All brands have their own software to install on your PC and in most cases you can get the software for Windows or for the Mac.

What will you be missing?

Dive Planner

Usually you will not find a built-in dive planner in this price category. However, you should be able to offload the data to your computer and perform dive plans on the PC.

Air integration

Air integration is nothing you will find in this price category. You might get lucky and find a DC on sale that is capable of air integration but you most certainly will not get a device that has an air transmitter included.

Digital Compass

Integrated digital compasses are something you will have to look at the next price level. Usually, these devices will be more in the $800 to $1,000 range where you can see digital compasses being part of the feature set of the DC.

Suunto Vyper Air Dive Computer Review

The Suunto Vyper Air is the third member of the Vyper Dive Computer Family. It's not as capable as the Vyper Novo yet has air integration and a compass built in which separates it from the Suunto Vyper.

While it is an oversized dive watch, it does have a lot more resemblance to a watch than the other two models in the Vyper family. Yet, it is pretty large and roughly the same size as the Vyper model is.

Conclusion

​The Suunto Vyper Air provides all the features a recreational diver would need. Ant it all comes at a very reasonable price.

You get a full-featured dive computer that works reliably. The optional air integration allows to expand the capabilities at a later time when you require them.​

If you want most of the features offered by the Vyper Air but don't need a compass, air integration and to use two gas mixes then have a look at the review of the Suunto Vyper or even of the Suunto Zoop Novo. The Vyper is around the same price as the Vyper Air while the Zoop Novo is quite a bit cheaper.

Whom is the SUUNTO Vyper Air not for?

The Vyper Air satisfies the requirements that any recreational diver has. Technical divers might require more than two gas mixes but otherwise you get all functions you can think of.

It's a dive computer that has enough features for any experience level. Even a beginner could invest in it and then add air integration at a later time.

Having all functions that are required results in a dive computer that will support you during your dives for years to come. The Suunto Vyper Air offers what you need and all that at a really great price!

Suunto Vyper Novo vs. Zoop Novo

Comparing the Suunto Vyper Novo with the Suunto Zoop Novo

Suunto Vyper Novo Air Integrated Dive Computer White

The Vyper Novo and the Zoop Novo are the successors of the Vyper and Zoop. Each in their own category added a lot more features than the predecessor models. You can however still buy the Zoop and Vyper today in case you are looking for dive computers that cost less.

For detailed information on each of the models read the review of the Suuntu Vyper Novo and the Suunto Zoop Novo review. You will find in-depth information on both of these dive computers.​

In this comparison we wanted to have a look at the differences between the two models. They do target very different divers with regards to their experience.

The Zoop Novo is designed for the beginner diver. It has sufficient capabilities to work for most recreational divers. Once you want to start technical diving and need multiple gas mixes as well as air integration you want to have a closer look at the Vyper Novo.

Design Differences

At first glance you'd think these two dive computers are twins. They do look very similar yet the Vyper Novo is a little larger in diameter and height compared to the Zoop Novo.

Both dive computers are designed to be worn at the wrist. The Zoop Novo is also available as a console version if you prefer to use your dive computer in the console.

The size difference between the two dive computers is not as large as the comparison above suggests. The diameter of Vyper Novo is around 0.2 inches larger than the Zoop Novo. The Zoop Novo comes in three different colors (Blue, Lime, Black) while the Vyper Novo comes in Black and White.

​The displays on both devices are very similar in quality. They are large and provide the essential information on one screen. Both have backlights and also are phosphor-luminescent so they glow in the dark if you shine your dive light onto them. The Zoop Novo is lacking a number of features that the Vyper Novo has and that explains the different data being displayed.

Features and Functions

The list of features has been significantly expanded. The Vyper Novo is a true high-end dive computer now. The Vyper is barely above the entry-level in comparison.

The Vyper Novo provides a lot more features than the Zoop Novo. It's designed for a completely different type of diver. The features provided satisfy most technical and recreational divers. The Zoop is designed as an entry-level dive computer that targets beginner divers and divers that don't need the ability to dive with several gas mixes or have air integration.

While the Zoop Novo is capable of handling Nitrox up to 50%, the Vyper Novo can handle three different gas mixes up to 100% oxygen. Additionally, each of these three gas mixes (tanks) can be wirelessly integrated to track the dive time remaining. The Vyper Novo also has a digital compass integrated.

Both offer five modes - air, nitrox, gauge, free diving and off. The log capacity in both dive computers is the same at 140 hours at a sampling rate of 20 seconds. Sampling rates are adjustable.

The algorithm in both models can handle Deep Stops which the predecessors could not deal with. The Vyper Novo's version of the Suunto RGBM can deal with three different gas mixes compared to the one gas mix in the Zoop Novo. Both dive computers support two conservatism adjustment settings to the base algorithm to make it more conservative.

Suunto Vyper Novo Wrist Dive Computer with Transmitter White

Conclusion

The Vyper Novo and the Zoop Novo do not really compare. They have completely different feature sets and target different experience levels and types of divers. The Vyper Novo is  full-featured dive computer with all the bells and whistles you can ask for. Considering that you can add the air integration at a later time it is not that outrageously expensive. It's certainly a lot more in cost than the Zoop Novo.

If you are just starting with diving or don't dive very often the the Zoop Novo is a great device for you. The feature set will be enough for the next years to come and who knows what new kinds of dive computers we will have by then.

When you have a few years of diving experience and you do technical dives with multiple gas mixes then the Vyper Novo is a great companion for your dives. The optional air integration makes it easy to track your gas consumption during a dive.

If you are not that experienced yet but you are already thinking of dives using multiple gases then you might consider getting the Vyper Novo even though you might not use its advanced right at this moment. You will save money though as you're not buying an entry-level dive computer just to then having to trade up in a year or so.

Suunto Vyper Novo vs. Vyper

Comparing the Suunto Vyper Novo with the Suunto Vyper

Suunto Vyper Novo Air Integrated Dive Computer White

Suunto introduced the Vyper Novo as the successor of the Vyper. To confused matters more, they decided to still keep the Vyper in their product line. However, the Novo has seen a significant increase in functionality and features compared to the original dive computer.

You can read our review of the Suunto Vyper Novo as well as the Suunto Vyper to learn more about their features and capabilities.​

Below we'll look at the differences between the two models so you can make an educated choice which one of them matches your needs better.

Design Differences

Both these dive computers are worn on the wrist. They are oversized and pretty similar in size. The Novo version has four buttons for selecting the menu items and the Vyper features three. This is due to the additional features that the Vyper Novo offers and also to allow to use the design of the Suunto Zoop Novo that was introduced at the same time.

Suunto Vyper Novo Air Integrated Dive Computer Black

Suunto Vyper Novo in black

Suunty Vyper Wrist Computer

Suunto Vyper

The Novo is larger in size by nearly half an inch. The most significant increase is the weight though. It practically doubled to 134 grams up from 68 grams for the Vyper. A decent amount of weight is due to the larger size and packing more electronics into it. Otherwise, one would assume that the Vyper Novo might also be built somewhat sturdier.

​The display seems a little more refined on the Novo. The data is easy to read and all essential information is displayed on the main screen. The original Vyper has less functionality and as such it looks like the data on the display is somewhat more spread out with areas that are simply not filled.

The backlight on the display has been improved significantly. The screen on the Vyper Novo is additionally phosphor-luminescent so it glows in the dark when you shine a dive light at it. That can help you conserve battery as you won't need to switch on the backlight.

Features and Functions

The list of features has been significantly expanded. The Vyper Novo is a true high-end dive computer now. The Vyper is barely above the entry-level in comparison.

The Vyper Novo is based on its additional features in a completely different class that the Vyper. While the Vyper today is basically a dive computer that's one level above an entry-level device, the Novo is a dive computer with a complete set of features. You get air integration, handling of three gas mixes including switching them during a dive, a compass and a variety of dive modes. The Vyper can handle one gas mix and has none of the other features that the Novo offers.

Even the logbook capacity doesn't compare. The Vyper can handle around 36 hours of collected dive data while the Vyper Novo can handle up to 140 hours.  As the Novo has a freediving mode, Suunto also added a configurable sampling rate for that mode. You can adjust the rate to 1, 2 and 5 seconds.

The algorithm in the Novo can handle Deep Stops now in addition to dealing with three different gas mixes. The original version could handle one gas mix.

Suunto Vyper Novo Wrist Dive Computer with Transmitter White

Conclusion

Honestly, there's no comparison between the Vyper Novo and the Vyper. The Novo is in a completely different class. Yet, that's not only with regards to functionality but also when you look at the price. You will have to add a few hundred dollars on top of the price of the Vyper when you want to get a Novo. However, you do get that much more!

The increased log book on top of the new features is a bonus. But the big difference is that the Novo has all the features that a recreational diver might ever ask for. The Vyper simply does not even though it is a good dive computer which has the features that a medium experienced recreational diver would need.

If you are fairly new to diving then the Vyper is a great choice. It'll be sufficient for years to come. If you are an experienced diver and you want a dive computer that has a complete set of features and can grow through optional air integration then have a closer look at the Vyper Novo. Pricing for both is what you'd expect for the features you get. Click here to find the lowest price!

Suunto Vyper Dive Computer Review

The Suunto Vyper has been available on the market for quite a few years now. This does not mean that it's an old dive computer but it does provide less capabilities than for example the Suunto Vyper Novo. However, it still does offer a lot of functionality for the recreational diver at a much lower price than the Novo model!

You get an oversized wrist dive computer with a pretty complete set of features required for a medium-experienced recreational diver. The functions you miss compared to higher end devices are possibly nothing you'll need for years or maybe even ever.

Summary:

The Suunto Vyper is not the newest dive computer that you can buy. However, it does have pretty much everything you need during your first years of diving. Might you miss the ability to handle more than one gas mix and to have air integration? You eventually might miss it but that's usually a few years down the road. As such, you can save yourself some money today and get a reliable device like the Vyper. When it comes to upgrading to a more sophisticated model, new technology might already have brought out new dive computers that are more capable than today's.

Suunto Vyper Novo Wrist Dive Computer with Transmitter Black

The large display shows the important data at a glance. The information is showing clearly visible and in their separate sections.

The Vyper is a wrist mounted diving computer. It does not come as a console mount. It is, as most wrist dive computers, too large to be used as a regular watch.





Capabilities

The Suunto Vyper has a large screen which allows to view all data required for a safe dive without having to navigate to get to it.

It offers three different dive modes:

Suunto Vyper Dive Computer

This is a no-nonsense dive computer that sports the most important features for recreational diving. It doesn't offer functionalities like air-integration or gas mixes and switching.

The visual alarms show on the main display without the need to navigate away from the main screen. The same is the case if the battery gets low. A low battery indicator will show on the screen reminding you to switch the battery. The battery is easily changed by you with no need to send the device off to a service center. This saves money and speeds up the replacement of the battery.

The navigation on this device is easy and consists in the usage of three buttons. They are spaced out on the top of the dive computer. This also ensures that you press the right button even if you wear gloves during the dive.

The Vyper has the most important alarms available. They alert you both visually and through sound when the limits for the following settings are violated:

  • Dive Time
  • Max. Depth
  • High PO2
  • Decompression ceiling violation
  • Too fast ascent

Technical Capabilities

​The Suunto Vyper can handle one gas mixture between 21% and 50%. It cannot handle different gas mixes during dive. You can set the pO2 limits between 1.2 and 1.6 bar.

The Vyper has a max. operational depth of 100 m (328 ft). If you intend to dive at higher altitudes then you can specify the height up to 3,000 meters (9,843 ft) in four steps. This will allow the algorithm to calculate all data correctly.

The calculations are all based on the Suunto RGBM algorithm. It's used in all Suunto dive computers and is known to be a reliable yet conservative algorithm. The Suunto Vyper is able to have you change the conservatism settings through two different settings to influence the calculations.

Dive Log and Connectivity

​The dive log is on the small side with being able to hold dive data for around 36 hours when the sampling rate is set to 20 seconds. The sampling rate can be adjusted and set to 10, 20, 30 or 60 seconds.

Th​e Suunto Vyper can be linked to your computer through a USB cable. You have to install Suunto's DM5 software on your computer to allow to download the dive data from your dive computer. The software enables you to analyze your log data from a dive or to plan future dives.

The log data can also be uploaded to the Suunto Movescount portal. There you can add information including videos and photographs and share the information with others.

Missing Functionality

The SUUNTO Vyper provides the most needed features and functions you need as a recreational diver. It is missing the ability to handle multiple gas mixes and it also has no air integration. Lastly, it also does not provide an integrated compass.

Features/Specifications

  • Easy navigation with three buttons
  • Most important alarms are visible and audible when limits get violated
  • Large display showing all necessary data at a glance
  • Three dive mode settings for Air, Nitrox and Gauge
  • One gas mix from 21% to 50%
  • Set pPO2 limits between 1.2 and 1.6 bars
  • Adjustable Suunto RGBM algorithm with 2 conservatism settings
  • Max. operating depth of 100 meters/328 feet
  • Altitude settings up to 3,000 m (9,843 ft) in four different settings
  • Can handle data in either imperial or metric data
  • Around 36 hours of dive data in the log at a sampling rate of 20 seconds
  • Sampling rate adjustable to be 10, 20, 30 or 60 seconds
  • User replaceable battery

Pros and Cons

You get a robust and reliable dive computer when you purchase the Suunto Vyper. It does not have high-end features and functions but it does provide the essentials you need as a recreational diver.

When it gets time to upgrade to more sophisticated features you will have to trade up. However, that would most likely be years out in the future if it ever happens at all.

Pros

  • Navigation through 3 easy to use buttons
  • Suunto RGBM algorithm with 2 adjustment settings
  • Three different dive modes (Air, Nitrox and Gauge)
  • Basic features that a recreational diver requires

Cons

  • Not a wrist watch
  • No air integration
  • No compass
  • No gas switching

As a recreational diver you might not require more features even in the long run. It could be a wise move to buy this dive computer and save some money compared to other higher-end models while still getting a solid and reliable device that can handle all your essential requirements.

Conclusion

​The Suunto Vyper is not the latest and greatest gadget you can get. It does not have all the bells and whistles you might need to show off your dive computer to your buddies.

However, it is a robust and reliable partner that will help you to dive safely. It offers the essential features you need as a recreational divers without the bells and whistles that you might or might not need when you do more sophisticated dives.

If you're looking for an even more basic entry-level dive computer then have a look at our review of the  Suunto Zoop Novo. It is cheaper and offers the basic features that you need when beginning with the scuba diving sport.

Whom is the SUUNTO Vyper not for?

The Vyper is a good and solid dive computer for a diver with some experience that doesn't need to spend the extra money on multiple gases and/or air integration. To say it differently, if you do have the need to dive with multiple mixes and/or to have wireless air integration then this is not the scuba computer for you.

You get a lot of dive computer for the money. You won't get the highest-end and most sophisticated features but you do get a solid scuba computer for years to come. If you need a dive computer with more features then you might want to look at the Suunto Vyper Novo.

Suunto Vyper Novo Dive Computer Review

When you look at the Suunto Vyper Novo and you think you actually might be looking at the Zoop Novo then you are correct. They look like twins. Yet, under the hood (so to speak) there are a lot of differences.

The Vyper Novo sports a large display and high-end functionality that is reflected in the price. The large screen allows to display all essential information at a glance.


Review Summary of the Suuntu Vyper Novo Dive Computer

Experience Level

Targeting the experienced recreational diver.

STYLE

Wrist dive computer with a large screen.

Ease of Use

Four buttons that are spaced far apart for easy and fast navigation.

Price Level

There's not much if anything you're missing in functionality. The price reflects that.

We Like

  • Large and clearly readable display
  • Intuitive navigation with four buttons
  • Features for experienced diver
  • Large log book with 140 hrs of dive time logging
  • Optional air integration

We Don't Like

  • Too large to wear as a watch

Summary:

Suunto scored a home-run with this dive computer. It really doesn't lack any functionality you might ever ask for as a recreational diver. The optional air integration makes it a device that will grow with your needs. You can use up to three transmitters for three tanks. Last but not least, you have a 3D digital compass in the watch computer to free you from another instrument to dive with. The device is at a reasonable price point considering all the functionality included.

Suunto Vyper Novo Wrist Dive Computer with Transmitter Black

The display is large and cleanly divided to show all data you need to have in one view. There switching between functions is easy and quick through the clear four button navigation.


The Vyper Novo is available in two different colors:

  • Black
  • White

​Even though the Suunto Vyper Novo is worn at the wrist, it's anything but a wrist watch. It's pretty large and not what you'd wear day-to-day. This large size makes it easy though to view all data on the display under water. Being a dive computer this is more important than being used as a wrist watch.




Capabilities

The Suunto Vyper Novo is a wrist dive computer. The size is large which provides a lot of real estate on the screen to display all important information.

It offers five different dive modes:

  • Air
  • Nitrox
  • Gauge
  • Free Diving
  • Off
Suunto Vyper Novo White

The Suunto Vyper Novo is a dive computer that is worn at the wrist. There is no console version of it. It has optional air integration which is working wireless.

The large size of the display allows to show all important information on the screen. You will be able to see everything you need to know including the air time remaining (if you use air integration) on the screen.

The only functionality that needs switching is to view the compass. A lower battery capacity will also show clearly on the display to remind you to change the battery before you take the dive computer under water.

The battery can be changed by you which is very convenient. Some other smaller dive computers have to be sent to service centers for a battery change which causes additional costs and time without the device.

Navigation to get to secondary functions like the log book can be easily accessed through the simple four button design. The buttons are spaced far apart so you won't run the risk of pressing a wrong button by accident when you wear thick gloves.

The Suunto Vyper Novo provides a range of visual and audible alarms for the following conditions:

  • Dive Time
  • Maximum Depth
  • Tank pressure
  • Gas time
  • High PO2
  • Decompression ceiling violation
  • Deepstop violation
  • CNS/OTU (OLF) 80% / 100%
  • Switch gas (better gas is available)

Technical Capabilities

​This dive computer is able to handle three different gasses with oxygen levels between 21% and 99%. The pO2 limits can be set between 1.2 and 1.6 bars.

The maximum operational dive depth is 80 m (262 ft). There are altitude adjustments available to specify the altitude in four different settings up to 3,000 meters (9,843 ft).

​The wrist computer uses Suunto's RGBM algorithm. It's in all their models and is developed in cooperation with Dr. Bruce Wienke. You can adjust the conservatism of the algorithm with two different settings. This way you can set a more conservative dive profile.

The off mode is a nice feature. Setting the dive computer into that mode prevents it from switching itself on when you take it into the water. This way you can conserve battery life.

Dive Log and Connectivity

​The dive log is rather large and can hold data for up to 140 hours at a sampling rate of 20 seconds. You can adjust the sampling rate to be either 10, 20, 30 or 60 seconds. For freediving you can set the sampling to 1, 2, or 5 seconds.

The data can be transferred to your computer through a USB cable. Suunto's software on the computer is the DM5 application. You can load your data into the software to analyze past dive data or plan future dives.

You can additionally upload your dive data to the Suunto Movescount portal. You can then share your data with friends and family and even add photos and video to it.

Missing Functionality

There's not much missing with the Vyper Novo. It's easy to use and has all the functionalities that a recreational diver could ask for.

You can start with getting the dive computer itself and later add the wireless transmitters as needed. This will save you money and you can expand the capabilities as you go and gain more experience.​

Features/Specifications

  • Simple 4 button navigation
  • Numerous audible and visual alarms
  • Large display showing all necessary data at a glance
  • Five dive mode settings for Air, Nitrox, Gauge, Freedive and Off Mode
  • Three gas mixes from 21% to 100%
  • pPO2 limits between 1.2 and 1.6 bars

  • 2 year limited warranty

Pros and Cons

The Suunto Vyper Novo provides all high-end functionality that a recreational diver could ask for. Being able to grow the capabilities of the dive computer by adding wireless transmitters for air integration at a later point of time allows to start with the dive computer only.

The Suunto RGBM algorithm is a somewhat conservative algorithm. You can adjust the conservatism in two levels yourself.

Pros

  • Simple and easy 4 button navigation
  • Adjustable Suunto RGBM algorithm
  • Five different dive modes (Air, Nitrox, Gauge, Freedive and Off)
  • Three gas mixes
  • Switch gases during dive
  • Air integration (optional)
  • 3D compass
  • All capabilities that an experienced recreational diver would require

Cons

  • Not a wrist watch

This dive computer is a great choice for a recreational diver. It does offer a ton of functionality and might be a little too much for a beginner. As an experienced diver you'll pretty much get everything you can ask for.

Conclusion

The Suunto Vyper Novo has everything you can ask for as a recreational diver. It'll take a long time, should it ever happen, that you require to dive with three gas mixes. In that case you'd be prepared with this dive computer. If you overall like the Suunto design and capabilities but do not need all those high-end features then have a look at the Suunto Zoop Novo instead. It's similar in design yet offerns only the features that are sufficient for most recreational divers.

The large display allows to view all essential and important data in one view. With air integration you can also see the current pressure and dive time remaining for up to three gas mixes. The built-in compass rounds out the set of features in this dive computer. These provided functions should be enough for many years of diving to come.

Whom is the SUUNTO Vyper Novo not for?

The Vyper Novo might be overkill for a beginner or if you dive only a few times a year. As an experienced diver or one that is working to become one it's a great dive computer will all neessary features.

There's not much you could ask for in functionality if you're diving. If you prefer a similarly capable recreational dive computer that is also usable as a daily wrist watch then have a look at the Mares Smart.

Hollis DG03 Dive Computer Review

Why was the Hollis DG03 recalled?

When Hollis introduced the DG03 to the market, it was a remarkable dive computer. Packed with features and compact in size.

Then, on July 11, 2013 Hollis issued a recall due to drowning hazard. The issue wasn’t with the dive computer itself but instead with the wireless transmitter. More on that below!


Review Summary of the Hollis DG03 Dive Computer

Experience Level

Recreational divers with experience

STYLE

Wrist style dive computer.

Ease of Use

Navigation based on three buttons.

Price Level

Not many to be found anymore. Prices are on the low side.

We Like

  • Large and easy-to-read display
  • Good backlight
  • Full set of functionality
  • Three gas mixes

We Don't Like

  • Navigation is cumbersome
  • Safety concerns after recall

Summary:

The Hollis DG03 is a full-featured dive computer. When it was introduced it was top of the line. The issues with the transmitter have resulted in the dive computer no longer being produced. The ones that are still available for sale are safe and very affordable for what they offer.

Hollis DG03 Dive Computer

The transmitter was optional and was supposed to measure the air pressure in the tank and submit the remaining air to the dive computer. Unfortunately, the transmitter could report wrong data which could then have the diver deplete their air under water without realizing it. This could result in the diver drowning.

So, the dive computer itself was not the issue, it was the transmitter. Hollis stopped the DG03 dive computer but did bring out a new update of the software.

Oceanic and Aeris affected?

Many divers asked themselves whether the Aeris Elite T3 or Oceanic VT3 had the same or similar issues as they are basically the same dive computers. All three brands are owned by the same company and the dive computers were/are simply rebranded.

It was/is good to know though that both the Oceanic and the Aeris had different software which means they weren’t affected by the issue. Today Hollis has a very limited amount of product offerings in the dive computer segment. Aeris has been completely absorbed into the Oceanic line of dive computers.

However, you can still find a Hollis DG03 being sold. They are safe after the software update and they are overall a great dive computer to have.

It is a personal wrist dive computer with a range of features. When Hollis introduced it, they packed a lot of features into it to mark a step up from the more basic models they had until then.





Capabilities

The DG03 supports the following dive modes:

  • Air
  • Nitrox
  • Gauge
  • Free Dive

The DG03 features a reasonably large and clearly separated display. It has a backlight which allows to read the displayed data in darkness.

Hollis DG03 Nitrox Dive Computer

Navigation on the DG03 is handled with three buttons. They allow to get and use the different menus and choices that the software offers. A number of divers mentioned that they found the navigation cumbersome and not very intuitive. The reality is that it takes a while to get used to the navigation but it’s not like one couldn’t master it.

The DG03 comes with all the audible and visual alarms you would expect from a modern dive computer:

  • Max Depth
  • Elapsed Dive Time
  • Dive Time Remaining
  • Turn Pressure
  • End Pressure

Technical Capabilities

The Hollis DG03 can handle up to three different gas mixes. Each mix can range from 21% to 100% Oxygen. You can even adjust the Nitrox percentages during a dive if that was ever needed.

You can switch between gases during a dive. Overall, the computer has a lot of sophisticated features that you would typically expect of a more expensive device.

Lastly, as already mentioned in the recall section above, you also have the ability to use air integration with this dive computer. The transmitter is optional and since the software update on the dive computer makes it safe to use.

The computer allows to connect to up to 3 transmitters. One for each tank if you dive with three gas mixes.

The underlying RGBM algorithm is moderate to conservative. If you want it more conservative then you have the option to adjust the safety factors.

Dive Log and Connectivity

The dive log capacity is less than on most other dive computers. It can store the data for the last 24 dives. If you need to keep more data then you have to get the optional USB cable to connect the DG03 to your computer to off-load the data.

Missing Functionality

The DG03 has a rather complete set of functions. The only thing missing might be the lack of a digital compass. Otherwise, there's not much you might not have and certainly more than what you'd expect to get at this price.

Features/Specifications

  • Navigation managed with three buttons
  • Both audible and visual alarms
  • Large display with good display of data
  • Four dive mode settings for Air, Nitrox, Gauge and Free Dive
  • Three Gas mix settings between 21% and 100%
  • Adjustable RGBM algorithm
  • Max. operating depth 120 meters/393 feet
  • Seven altitude settings up to 14,000 ft (4,270 meters)
  • Display either imperial or metric data
  • Dive log up to 24 dives

Pros and Cons

The Hollis DG03 is a full-featured dive computer for the experienced recreational diver. It is no longer produced yet you can still purchase it.

The pricing is great on the units you can find for purchase.

Pros

  • Three button navigation
  • Adjustable RGBM algorithm
  • Four different dive modes (Air, Nitrox, Gauge and Free Dive)
  • Three Gas mixes
  • Gas switching while diving
  • Air integration with up to three transmitters

Cons

  • No compass
  • Safety concerns after recall

The DG03 is a great choice of dive computer if it's updated with the software that removes the issues that lead to the recall. You can get it at a great price for the functionality it provides. The downside is that Hollis won't produce anymore updates.

Where to Buy?

There's not many DG03's available anymore. The best prices can usually be gotten on Amazon. Click the button below to find the lowest price!

Customer Feedback

Customer reviews all over the internet speak positively with the exception of the navigation/software. It's not too intuitive and as such you need to get used to how it works. Once you master it, the dive computer is as easy to use as any other on the market.

Hollis DG03 Display

Conclusion

For the price you get one of the most capable dive computers around. You can add optional air integration to measure the levels of gas in up to three tanks.

The screen is setup nicely and can be read easily. The backlight is strong and makes it easy to read the display in the dark.

You can use up to three gas mixes. The gas mixes can be switched during a dive and you can also change the percentages of Oxygen in the gas mixes during a dive.

A recreational diver will not miss any functionality with the Hollis DC03. The only thing you might want for convenience is a compass. Otherwise, pretty much any functionality you could ask for is part of this scuba computer.
