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.

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


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


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


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.


  • 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.


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


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

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.

Atomic Aquatics Deluxe Regulator Bag

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 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.


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!

Tribord Easybreath vs. Seaview 180 Degree

Comparing the Seaview 180° and Tribord Easybreath Full-Face Snorkel Masks

If you hold both masks and look at them you’ll realize that they are both high-quality products. Yet, there’s one big difference. No, not the different colors…

The Seaview 180 Degree has a leg up to the Easybreath simply by having a GoPro mount as part of the mask. No fussing around with 3rd party mounts or having to hold the GoPro in your hands. You put it directly on the mask and it films what you see. It’s hard to see that there’d be anything easier than that.

A Look Back in Time

The first full-face snorkel mask was the Tribord Easybreath. It took the snorkel market and turned it upside down.

The design was simple and removed many obstacles that existed in the past preventing people from starting to take up snorkeling. The major news was the much larger field of view through the panoramic lens and the ability to breathe through mouth and nose.

The Tribord Easybreath in Blue.

All that combined with high-quality materials that guaranteed a comfortable fit made it the best choice for any snorkel mask. Well, until another competitor, Seaview, decided to make a mask of similar quality yet add the GoPro mount.

And that’s when it started that at least a large number of people looking for a top-quality full-face snorkel mask turned to the Seaview 180 Degree instead of the Tribord Easybreath. Now, that’s not to say that nobody gets the Easybreath anymore. Far from it. It overall is still one, if not the, most bought snorkel mask you can find.

And when it comes to comfort, visibility and quality, it still sets the gold standard. In our opinion together with the Seaview 180 and not by itself anymore.

Seaview 180 Degree vs. Tribord Easybreath

You might ask why would you even consider getting a Tribord when the Seaview is just as good and offers the GoPro mount? Well, there’s a few good reasons. If you don’t have a GoProd then there’s no need to have a mask with a mount.

The Seaview 180 Degree Mask in Teal

There’s also the point that GoPro might come out with a new camera next year that requires a different mount. Likely? Not really but you never know… In that case you’re better off with a 3rd party mount as you can simply switch that out versus having to buy a completely new mask.

The biggest point for getting a Tribord mask is that it comes in more sizes. Especially if you’re trying to get a mask for your children, then you might not find a good fitting size on the Seaview. You won’t have that problem with the Easybreath!

Another advantage of the Tribord is that it basically is impossible to fog it up. The breathing mechanism is so clever that there’s practically never any fogging inside the mask. The Seaview is nearly as good but there are situations where it can fog up. That can be annoying as you have to take it off and get the fogging taken care of.

Another advantage of the Tribord is that the tip of the snorkel is a bright signaling color. At first glance this might not seem important at all but if you’re snorkeling in crowded waters then it can be a good thing to have that bright orange part sticking out of the water and making you instantly visible to others around you.


If you have a GoPro and want to use it to make videos of your snorkel experience then the Seaview 180 Degree is the mask to go with. Otherwise, it depends. Both masks are of similar quality and make.

If you are a heavy breather then the Easybreath might be better suited for you. It practically never fogs up and breathing heavy won’t change that. The Seaview sometimes does get foggy.

Yet, for small faces the Tribord has better sizing and might fit more comfortable. The bright orange tip of the snorkel is a slight advantage.

No matter which of these two masks you pick, you’ll be happy with your purchase. Both are priced around the same and are overall very affordable. Both will provide you with an excellent snorkeling experience.

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.


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


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.


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.


  • 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.


  • 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


  • 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.

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.

Comparing the Ocean Reef Aria and Tribord Easybreath Full-Face Snorkel Masks

Looking at both of these full-face dive masks next to each other, then you certainly can see the resemblance. Some might even think these are twins. Yet, they are not and we’ll have a closer look at their background and differences.

The History

The Tribord Easybreath was and is the original full-face snorkel mask. It introduced this unique design to the world and offered the experience of snorkeling to a whole new group of people.

Before this mask you had to have a standard scuba diving mask and snorkel. For many people this was rather uncomfortable as they couldn’t breathe through their nose but had to use their mouth. And in more than one instance the snorkel would fill up with water and people instead of air sucked water.

Tribord Easybreath Full Face Snorkeling Mask

It’s also for many people not that much fun to constantly having to bite onto the mouth piece of the snorkel. Your teeth keep it in place and without the bite, the snorkel might just not do its job.

A wrong sitting mouth piece can actually cause quite some discomfort and you might get the inside of your mouth irritated. Or, if you bite too hard your jaws might start to hurt.

This turned off a lot of people from even trying to snorkel. The thought of an uncomfortable mask in combination with water gushing into your mouth was just not doing it.

The combination of all these downsides has led many people to not even try to snorkel or to simply give it up after one or a couple of trips.

Features of a full-face snorkel mask

Tribord developed the full-face mask and it actually addressed a lot of these issues. First, the mask covers your whole face and you can breathe through your mouth or nose.

The larger mask also allows a larger field of view lifting the underwater experience to a completely new level. You can see pretty much as much to the right, left, up and down as you can without wearing a mask. This is quite a difference compared to a standard scuba mask.

Lastly, this all got combined with a dry snorkel that is permanently attached to the top of the mask. The dry snorkel will not allow water in and the placement allows for a very comfortable snorkeling experience.

They also added a purge valve allowing you to quickly get rid of all water that somehow might have found its way into the mask. Press it and blow and the water is reliably forced out of the mask. Very easy to perform and you don’t have to take the mask off or adjust it in any way.

Ocean Reef vs. Tribord Easybreath

You might ask yourself why we haven’t yet brought up much about the Ocean Reef Aria. It’s newer in design compared to the Easybreath. One would expect that it should be better.

Unfortunately, it’s not. It just simply a knock-off of the Tribord and doesn’t really add anything that would suggest that you should use the Aria over the Easybreath.

Ocean Reef Aria Full Face Snorkel Mask

​You might certainly prefer the grey and orange color scheme of the Aria vs. the different colors you can get the Easybreath in. However, besides those cosmetics there's nothing that would technically lift the Aria above the original mask.

Having said that, the Ocean Reef is a high-quality mask and there’s nothing wrong with it. It just feels like yet another one that tries to imitate the Tribord design without adding anything at all. Well, except for the additional dollars that are required to get it!


In our opinion, we suggest that you get the original mask for the simple reasons that the purge mechanism in our opinion is slightly better. But that’s not all, the Easybreath is usually also cheaper than the Aria and why would you want to spend more for a knock-off that doesn’t feel as capable as the original?

If you are on a vacation and want to try out snorkeling but can only get your hands on the Ocean Reef Aria, then by all means get it. It’s a good mask and you won’t regret having it!

Scuba Diving Regulator Buying Guide

A lot of scuba gear is very technical and the most technical of them all are your regulators. Well, besides your personal diving computer that is.

Your regulator should also be one of the first pieces of gear you purchase. Why? Well, how do you feel about using a mouthpiece that others have used and you have no idea who that might have been? Yes, it’s been cleaned but…

It’s also essential as one of your first items to get simply because it’s the part of your gear that allows you to breath. As that’s very important under water, you might consider it your possibly most important piece of gear overall! And, as it does allow you to breathe under water, you want to make sure you get a good piece of equipment and that you maintain it to keep it in good shape!

This buying guide will educate you on the different pieces of your regulator. These are the first and second stage, the octo and the hoses. Lastly, we’ll quickly touch on the different gauge options you have to control your air use and what you have left.

You will usually purchase your first and second stage regulators as a package. That makes sense as you want those two pieces to match and work flawlessly with each other! You’ll know exactly what to buy when you’re through with this guide.

First Stage

Scubapro MK 21 First Stage Regulator for diving

Click here for more information and pricing for the Scubapro MK 21 First Stage Regulator 

The first stage of a regulator for scuba diving is designed to reduce the air pressure from the tank into a more manageable pressure that can be used in flexible hoses. This pressure level is called intermediate pressure.

It is attached directly to the valve on the tank. Your tank has the air or gas mix under high pressure and the first stage regulates that pressure going into the hose right after that. The first stage is also the point where you attach your gauge for air pressure or your wireless air transmitter for your dive computer as well as your BC and octo!

There are some differences in first stages when you’re looking to buy. Here’s an overview of what you have to consider and what the different options mean for you.

DIN vs. Yoke

Your first consideration is the type of how you attach your first stage to your tank. Many regulators are available as either DIN or yoke.

A DIN first stage screw directly into the tank valve. This is the safest way to connect your first stage to a tank valve. Not only does it sit safely due to being screwed in but it also restricts any movement of the high-pressure O-ring seal that prevents air from escaping. This system is mostly used by technical divers as it can handle higher tank pressures.

The yoke system is somewhat simpler but fully sufficient for recreational diving. In this setup the regulator is slipped over the top of the valve and then secured and held in place with a large bolt. It’s somewhat easier to handle and safe to use in recreational diving.

Most tanks that you can rent will have a yoke attachment. A DIN regulator requires a compatible tank and not all dive shops have them. However, if you have a DIN regulator you can get a simple and low-cost adapter to convert it to a yoke system if the tank does not allow to use a DIN regulator.

You definitely want to purchase such a converter if you opt to buy a DIN regulator. You might otherwise find out the hard way that the available tanks in the dive shop will be of no use to you!

Balanced vs. Unbalanced

In the past you had a pretty significant different in performance between these two types of systems. In the meantime most of these differences have been minimized and most (recreational) divers cannot distinguish once they’re under water.

The difference is simply in how they work and how much they cost. A balanced regulator delivers the air at a constant pressure to the second stage and the diver. It is in no way affected by the pressure of the water surrounding you or the pressure of the air in the tank itself!

An unbalanced system relies on the surrounding pressure as well as the pressure inside the tank. Modern unbalanced systems minimize those effects and you barely notice a difference.

Having said that, most divers prefer a balanced setup if they can afford it. Otherwise, opt for a high-quality unbalanced type and you’ll barely notice a difference in recreational dive environments.

Diaphragm vs. Piston

Yet again there are two different types of setups that are used to connect the high pressure air into lower pressure for the second stage regulator and other attachments. Both setups work fine for most recreational diving.

Piston regulators are overall simpler as they have a minimal amount of moving parts. This enhances the durability and reduces maintenance costs. However, most of these first stage regulators allow water into them and as such you have a higher level of care after a dive to keep them clean and prevent corrosion.

Diaphragm regulators have more moving components and usually are not as durable as piston regulators. However, they are much cheaper to manufacture which usually results in a lower price for you.

They come in two different flavors. You can get them either as environmentally sealed or unsealed. If you only dive in the tropics then an unsealed regulator is perfectly fine. If you want to mix up your dive environments then you’re better off using an environmentally sealed setup.

For a recreational diver it makes the most sense to look for an environmentally sealed first stage diaphragm regulator that has a long warranty. Also make sure to use a well-known brand so you know you can get spare parts if needed!

Number of Connection Ports

Most modern first stage regulators will have enough ports to allow you to connect your second stage, your gauge or computer and your BCD as well as a port for the octopus regulator if needed.

If you dive with a dry suit or need more ports to connect additional accessories and devices then you have to make sure that your first stage has enough ports to handle everything want to connect!

Second Stage

The second stage is the piece of the setup which you have in your mouth and that allows you to breathe. You’ll often see this second stage being referred to as the regulator. It takes the air from the first stage (through a hose) and reduces the pressure so you can comfortably breathe.

Similar to the first stage you can either have a diaphragm or piston setup in your second stage. Your second stage also has a purge button, a mouth piece and an exhaust valve. The purge button allows you to clear any water from the setup. The exhaust valve allows your exhaled air to escape and finally the mouthpiece allows you to keep the regulator securely in your mouth without having to hold on to it.

But there are additional things to consider and look for when you’re looking at the second stage.

Purge Button

The purge button is there to allow you to clear your regulator. Pressing it forces the water out of the second stage so you can breathe easily.

You want to make sure that your regulator has a large enough purge button so that you can conveniently press it when needed. If the button is too small then you might have to fumble trying to press it if you’re wearing dive gloves.


You can often find a number of controls on your regulator. First, you can have the possibility to adjust the air flow so you can fine tune the amount of air being delivered for your breathing. This is helpful when you dive deeper as it allows to make sure that you can comfortably breathe.

Another adjustment that is commonly found is to be able to set the regulator into ‘dive mode’. If you switch this mode off while you’re above the surface then it prevents air to free flow. It’s harder to breathe in that case but you’re not wasting air.

These adjustment controls are in most circumstances ‘nice-to-have’ features that you can live without especially if you’re recreationally diving.


The weight of the second stage can be of importance to you. It’s the piece of equipment that you hold with your mouth and teeth and it can over time cause fatigue of the jaw.

Overall, the second stage is of neutral buoyancy and as such the weight under water should be of limited concern. However, above water a heavy regulator can be somewhat tedious to wear and deal with.

Mouth Piece

The mouth piece must fit comfortable. Most modern second stage regulators have ergonomically shaped mouth pieces and as such you should be fine.

For repairs you want the mouth piece to be replaceable. This is pretty much true for all new regulators but you have to have a look at how the mouth piece connects to the rest of the hardware. You can find proprietary mounting options or zip ties. In any case, you want to make sure you have the right spare parts in your repair kit!

Octopus Regulator

The octopus is nothing else than a spare or alternate second stage regulator. It is used to allow your dive buddy to breathe if he or she runs out of air or if your second stage regulator fails for whatever reason.

These octo regulators are only to be used as a backup and as such are usually less complex and of simpler design as your primary second stage regulator. In a typical dive setting you will never use your octo as it’s only there for emergencies.

Dive standards do require that the octo is easily accessible and clearly visible. Most octo’s are bright in color to make them stand out and to be easily identifiable. Most of today’s BCD’s also have a pocket to store the octo for easy access in case of an emergency.

One of the things that is easily overseen with octo regulators is that they require the same care and maintenance as your other gear. Make sure to keep your octo clean and perform all pre-dive and post-dive checks and maintenance steps that you also perform on your standard second stage regulator!


Your regulator setup not only consists of the first and second stage but also comes with a bunch of different hoses to connect both stages as well as additional accessories.

Hose to Connect First and Second Stage

This is usually a medium pressure hose that is used to connect the two stages. For many years the only available option you had was a rubber hose.

In the last few years many manufacturers started to provide braided hoses. However, there has been a few instances where these types of hoses had to be recalled and as such divers today still tend to prefer a rubber hose.

A braided hose has some advantages though. They are usually lighter and more flexible and as such more convenient to deal with. A new braided hose should also be more durable than a rubber hose.

Inflation Hoses

This type of hose connects the first stage to your BCD. You’ll need this link in order to be able to regulate your buoyancy through your BCD. You can either get a rubber hose or braided hoses which are lightweight and bendable.

Some BCD’s come with an octo regulator built into the inflator. In that case you will usually require a special connector. You want to be aware of that when ordering your hoses.

Hoses for Gauges and/or Dive Computer

You will usually have at least one gauge to monitor your tank pressure. Some divers prefer to use a analog gauge as well as a dive computer with air integration to monitor the pressure in their tank.

These hoses are usually high pressure hoses. If you’re choosing an air-integrated dive computer that has a wireless setup then your pressure monitor will sit directly on the first stage and wirelessly send the data to your dive computer. This will save you from dealing with yet another hose. However, it does make some divers uneasy to think of a non-mechanical way to measure how much air is left!


Most of the well-known brands will have regulator setups that are sufficient for any recreational diver. If you can then spend a few extra-bucks to get a setup of the highest quality. If you get a first stage with a DIN connector then make sure that you do purchase an adapter to make it usable with a yoke connector to ensure you won’t have to watch your buddies dive while you stay on land!

Best Scuba Diving Fins

The Ultimate Guide to Find the Best Scuba Fins

Fins are an essential part of your scuba gear. They propel you underwater and make or break your dive experience.

If you don’t own your own set of scuba fins you will rely on the dive shop to have some to rent. In many cases, you’ll end up with lower quality fins that kind of fit but are not really comfortable. It can seriously put a damper on your dive experience!

Having your own gear and having it fit perfectly is important in scuba diving. The familiarity you gain with your gear improves your precision during dives and builds your trust into your gear.

Scuba fins should be comfortable and provide you with the ability to transform the power from your kicks into forward motion. Along with that they should be easy to put on and off, to transport and certainly sturdy enough to last a long time.

Mares Avanti Quattro Plus – Best Overall Open Heel Scuba Fins

The Mares Avanti Quattro Plus are open heel scuba fins. They have a bungee strap so you’re able to quickly get in and out of them. The huge advantage is also that you won’t have to adjust any straps. Simply slide in and let the bungee strap do the rest.

This fin is made from somewhat stiffer material which is combined with four soft channels to provide the most possible thrust when kicking. The blade is overall a little more stiff than other dive fins. However, it creates a lot of thrust with each kick!

Mares Avanti Quattro Plus Open Heel Bungee Strap Fin

These scuba fins come in four different sizes and a large variety of colors. You’ll find the perfect fit amongst those four sizes as the bungee strap makes sure that you’re securely in the fin once you put it on.

The Mares Avanti Quattro Plus is a great all-around choice for diving. It works well in warm and cold environments. It’s our overall best choice for a dive fin.

DiveRite XT – Best Open Heel Scuba Fins for Technical Diving

The first thing you’ll see when you look at the DiveRite XT is that it’s surprisingly non-flashy looking. Most newer fins have shapes and designs and color schemes that make them look ‘cool’. These fins are just what you see – excellent scuba diving fins.

They are specifically designed for strong and ripping currents and tougher conditions. They are made from a Monoprene blend which is used by DiveRite since the 1990’s in some of their best performing fins. The XT fins are designed as open heel fins with spring heel straps made from reinforced steel springs. This design provides a tight fit while being able to get in and out quickly.


The blades are designed to maximize the thrust with every kick while making sure that they stay stable in rough conditions. The DiveRite XT fins are a great choice for technical divers in varying conditions.

ScubaPro Seawing Nova – Best High Thrust Split Fins

The ScubaPro Seawing Nova offers a unique design. They combine the advantages of paddle fins and split fins. The design provides the thrust of a paddle fins with the comfort and efficiency of a split fin.

The design is unique in that it offers a joint in the blade that maximizes thrust while reducing drag through a pivoting motion. The fins offer tapered edges which make it useable for different kicking styles. The bungee strap makes it easy to get in and out of the fins and have the perfect fit.

Scuba Pro Seawing Nova Open Heel Fins

The fins come in five different sizes and a variety of color choices. The well designed and sturdy bungee strap ensures a perfect fit.

There’s no question that these are some of the best fins you can buy. However, the complex design results in one of the highest prices you can find for any scuba diving fins.

Atomic Aquatics – Best Split Fins

Atomic Aquatics is known for their high-end design of scuba gear and the Atomic Aquatics full foot split fins make no exception when it comes to quality. However, compared to other scuba gear from this manufacturer, they are actually affordable.

These fins have a full foot split design. During a kick the split blade changes shape into a pair of wings. These wings reduce drag when slicing through the water while creating thrust to propel you forward. This works great in calm waters but does not provide enough thrust in strong currents.

Atomic Aquatics High Performance Full Foot Split Fin

Overall these fins allow you to move through the water with less effort. They can help to reduce air consumption during a dive.

They come in six different sizes and two color combinations. Make sure to study the sizing information with your shoe size to find the best fit.

The Atomic Aquatics Full Foot Split Fins are a great choice for diving in calm warm waters. The split fin design reduces drag and helps you to conserve energy and air.

Tusa Solla – Best Affordable Scuba Fins

The Tusa Solla is an open heel paddle fin that has some very interesting features. It uses a thermoplastic elastomer mixing hard and soft materials within the blade. The same combination of different stiffness levels is used in the side rails and the foot pocket. This improves the thrust while reducing the energy required to generate that thrust.

TUSA Open Heel Solla Dive Fins

The fins use an anatomically formed strap to secure your foot to the fin. While it’s not a bungee strap, it’s still easy to use and fits the back of your heel perfectly and comfortably.

The paddles are medium in size which provides a good compromise between maneuverability and thrust. The Tusa Solla is pretty affordable and definitely worth a look.

Mares X-Stream – Best Fins for Reduced Turbulence

The Mares X-Stream is one of the newer dive fins on the market. It is an open heel paddle scuba fin that has a comfortable foot pocket. The shape of the blade is rather unique and it is designed for less turbulence while you’re diving.

The X-Stream works on a similar split mechanism as the ScubaPro Seawing Nova in that it has a flex area right in front of the foot pocket that allows the blade to act like a split blade. This way the fin provides the thrust of a paddle fin with the reduced effort and drag from split fins.

Mares X-Stream Open Heel Fins

The strap is designed to provide a secure closure while your foot is in the fin. It’s comfortable to close and initially needs adjustment. A bungee strap would be a good change but the standard strap works fine.

The blade transfers your kick and transforms it into a powerful thrust forward. It features a center channel that is designed to force the water down the blade instead of allowing it to spill over the sides. This reduces the energy needed to propel yourself through the water.

The Mares X-Stream come in four different sizes and a variety of different colors. They are not the cheapest pair of fins on the market but you get high-tech fins for a good price. They are certainly not more expensive compared to other high-quality fins on the market!

Cressi FROG Plus – Best Overall Paddle Fins

The Cressi FROG Plus fins are open heel paddle fins. Coming from Cressi you can trust to get highest quality and latest technology.

That’s not different for these fins. They are combining several materials into one fin to optimize the flow of water during a kick and reduce the drag.

Cressi FROG PLUS Open Heel Fins for Scuba Diving

They are designed to require the lowest amount of energy for each powerful thrust. The combination of the different materials provides strength and flexibility as needed during each kick.

The strap is adjustable and allows to get in and out of the fins quick and easy. While not a bungee strap, it’s still easy to initially adjust and use.

The Cressi FROG Plus comes in four different sizes and a few different colors. They are very affordable in price and made of highest quality products.

Sherwood Triton – Best ‘Old Style’ Dive Fins

The Sherwood Triton looks at first glance like a pretty old-fashioned scuba fin. However, it is anything than that. These are open heel paddle fins with an adjustable strap.

It features three vents in front of the foot pocket that are designed to increase the thrust on the downward motion of the kick. They also decrease the drag on the upward motion of the kick. This increases the thrust while reducing the energy needed to both kick and recover.

Sherwood Triton Fins

The strap is adjustable and offers quick-release buckles. The large heel pull tab makes it easy to put the fins on or take them off. A great feature of these fins is that they float. They are positively buoyant so they won’t sink to the bottom should you ever lose one in the water.

The Sherwood Triton comes in three different sizes and is only available in black. They are not any of those futuristic looking fins but rather look like fins from old times. Yet, when it comes to the power they produce they are top of the line. Due to their light weight they offer great flexibility when it comes to diving, snorkeling or even surface swimming with fins.

Pricing of the Sherwood Triton is what you would expect of a high-quality pair of fins. They won’t break the bank but are also not the cheapest fins you can find.

Tusa SF-15 X-PERT ZOOM Z3 – Best New Split Fins

The Tusa SF-15 X-PERT ZOOM Z3 are open heel split blade fins with a patented fin design. The blades are angled at 27 degrees. In combination with the three material design this creates a powerful thrust during a kick.

The blades are designed to provide a powerful thrust while using the least amount of energy. They combine three different materials to provide the stiffness where needed while offering the flexibility at other places. This allows to provide a quick response to any movement.

Tusa SF-15 X-PERT ZOOM Z3 Fins

The foot pocket is developed to increase the power transfer to the blades for improved performance. The multi-compound design of the pocket increases the comfort as well as improves the transfer of power to the fins.

The Tusa SF-15 X-PERT ZOOM Z3 comes in three sizes and four colors. Pricing for these fins is great for the quality you will get.

Things to Consider when Buying New Scuba Diving Fins

Without repeating the information you can find in the Scuba Fin Buying Guide, let’s have a quick look at the important factors you should consider when buying a new pair of scuba fins.

Full Foot or Open Heel Fins?

Full foot dive fins are usually better for snorkeling and for warm waters. You will have a harder time to get a tight fit compared to open heel fins.

Check out our Buying Guide for Scuba Fins for more information on those two kinds of foot pockets.

Split of Paddle Fins?

Split fins are a relatively new invention and innovation. They work like a propeller when you kick and the advantages are that you need less energy for a kick. However, in rough currents the power is simply not transferred as well and you won’t be able to maneuver quite as good as with a paddle fin.

You can find more information on split fins vs. regular fins to help you make the best choice!


The overall size of the fins can become an issue when you want to bring them for traveling. Most fins are ok to bring but some, specifically fins for freediving, are simply too large to pack. The ones reviewed above will all somehow fit into a suitcase but none of them are specifically designed for travel.

You can get travel fins which are either shorter or can be disassembled. This can be an important factor for you but you might consider trying to find a way to pack our preferred fins instead of compromising on either the quality or performance of your fins.

Other Considerations

There’s not much else to consider except that you need to make sure that you get fins that fit comfortable while keeping your foot secure in the foot pocket. Nothing’s worse than losing a fin during a dive!

Make sure that you get the right size of fins for your size of foot. If you wear booties during diving then take the additional size of those into consideration.

Lastly, and the least important consideration, is whether you want to get fins in a specific color. Color or patterns on the fins have no impact at all on the quality of the fin. However, if you have a specific color scheme going then you might not want to disrupt your colors of your wet suit, etc. with fins that don’t match at all.


​There is no one-size-fits-all when it comes to scuba fins. All of the fins we highlighted above are great fins.

In the end you will have to find out for yourself what style of diving you perform, in what surroundings you dive and how often you dive. It makes sense to have your own gear no matter what. As long as you don't specialize into specific types of diving you might simply go for fins that work in a variety of conditions.

Scuba Fin Buying Guide

What Fins are Best to Buy?

Scuba dive fins are an essential piece in the puzzle of getting all your dive gear. They are essential pieces of equipment whether you scuba dive, snorkel or free dive. For all three sports you need fins to propel yourself through the water.

Fins make it easier and reduce the effort that is required to have your body being propelled through the water. Whether it’s on the surface when you snorkel or deep down into the depths when you scuba dive or free dive.

Under water your legs do nearly all of the work to get you moving forward or down. The fins support the legs in being an extension that is optimized to need the least amount of muscle for the most amount of propulsion.

There are some minor and some major differences between the different fins you can buy. Some of them are due to the different sports they target while others are regarding to a completely different design of the fins.

This guide explains all the different fin options to you. The goal is for you to be able to decide on the best fins for your kind of dive or snorkel sport. We’re looking at the overall differences by sport, by foot pocket design and by fin design.

Different Types of Fins for Different Sports

You want to look at different kinds of fins depending on your kind of sport, whether it’s snorkeling, scuba or free diving. These different sports have small but distinctive different requirements for the fins you want to use.

Snorkel Fins

During snorkeling you will not or not often submerge. As you don’t need the added energy to go deep down under water, you will also not need a set of long fins. Fins for snorkeling are shorter and somewhat simpler than scuba or free-dive fins.

HEAD Mares Volo One Adjustable Snorkeling Fins

Not going under water requires less energy. Having long (or simply wrong) fins will make you feel like you are fighting your fins. If that is the case then try to go for shorter and lighter fins. They will be more comfortable and precise when aiding you during your snorkel excursions.

Scuba Diving Fins

When you scuba dive you need more power coming from your scuba fins. You need the additional power to be able to get down under water quick and with the least amount of effort.

Cressi PRO LIGHT Open Heel Scuba Diving Fins

Fins for scuba diving are usually around the same length as snorkel fins. They might be stiffer or have a slightly different design. Some scuba fins are a little longer than fins for snorkeling. Scuba fins do overall require more leg strength to effectively produce a powerful kick under water.

Free Diving Fins

Free diving requires a lot more propulsion than scuba diving or snorkeling. During free diving you try to dive very deep without using any air supply except for the air in your lungs.

Cressi Gara 3000 LD Fins

This requires to get down and back up as fast as possible. Therefore, free diving fins are usually longer to provide the strongest possible propulsion for each kick.

This significantly reduces the amount of kicks required during descent or ascent and therefore conserves oxygen. Longer fins help achieve this goal but also do require that your legs are strong enough to generate such powerful kicks.

Foot Pocket Types

You can find two different types of foot pockets when looking at fins for snorkeling or diving. First, there’s the full-foot design. The other type is the open heel fin. Both are very different in their design and in their use for specific environments and conditions.

Full-Foot Fins

Looking at full foot fins you will see that they are basically shoes with an attached fin. You slide into them like you slide into a shoe.

Cressi PLUMA Full Foot Lightweight Fins for Diving and Snorkeling

The problem is that if you’re not having a great fit then there’s nothing else you could adjust to make them fit better. When they fit correctly then they are the most comfortable type you can get.

They are best used in warm waters and for snorkeling. You will have an easy time to put them on or to get out of them. You also won’t need to wear booties.

Open Heel Fins

These kinds are the most used for scuba diving. Instead of a heel like in a shoe you have a strap around the heel to keep your foot in place.

Even if not diving in really cold water you will usually wear open heel fins with booties. That means that you have to measure for fit while wearing your booties!

U.S. Divers Proflex FX Fin

Open heel fins have the great advantage that you usually can replace the straps if they break. Full foot fins have to be thrown away if the heel breaks as there’s nothing that can be replaced. Being able to replace the straps is important when you consider that many of these scuba fins end up being quite expensive.

Most open heel fins have larger blades compared to full foot fins. The blade is often also stiffer. The combination of these two factors results in more thrust with each kick.

The larger blade and with that the larger fin makes it harder to travel though. They don’t fit as easily into your suitcase anymore and they usually also weigh more. If you travel a lot you want to consider both weight and length and possibly get a shorter and also lighter fin.

Styles of Fins

There are typically two different styles of blades to consider. You can either get split fins or paddle fins. Paddle fins are the most common ones and were the first type of fins used for scuba diving. Split fins are a relatively new invention and are seen more and more often.

Paddle fins are usually the most affordable kind of fin. They’ve been around for decades and are a proven design. The stiffness of the blade depends on the manufacturer but mostly all of these kinds of fins are easy to use and provide a controllable kick.

Mares Avanti Quattro Plus Open Heel Bungee Strap Fin

Split fins are designed to require less effort when kicking while producing the same thrust as a paddle fin. They are a great choice if you have ankle problems or you can’t generate a powerful kick. They are best used in calm waters. In heavy currents they get harder to use. Otherwise they can reduce your air consumption due to less effort to produce a kick.

Atomic Aquatics Split Fins

You can check out our Split Fins vs. Regular Fins article going into the differences and backgrounds behind both of these fin styles.

There are sub-types for each of these two main types. One of those is the channel blade fin. These fins have very stiff outside rails and the center area is flexible. They are probably not best suited for the beginner as they require a good understanding of your own kick strength. They can also be on the expensive side so you want to make sure you dive a lot in order to get your money’s worth.

Another sub type of fins are the ones with long blades for free diving or spearfishing. The only difference to paddle fins is that the blades are longer and provide more thrust.

Other Factors to Consider

Blade Design

The forward propulsion is generated through the blade of the fin. There are a variety of different designs and shapes of blades that are all having the same goal: provide as much propulsion and thrust under water as possible with the least amount of energy spent.

You can find numerous designs of blades. Some will have rails on the side for higher stiffness, others will have stiffer and softer areas throughout. You can even find blades with vents to reduce drag. You often also can see ribs on the blades which increase the firmness.

Shapes range from futuristic shapes coming out of computer programs to designs that resemble nature. Split fins have completely different shapes of the blades compared to paddle fins.

While all this can be confusing, be aware that as a beginner or recreational diver, you will not necessarily get much benefit out of using the latest and greatest with more or less ribs or rails. Many of these designs work very well in some situations but then on the other hand have disadvantages in other places.

Stiffness of the Blade

The stiffness of the blade is a rather subjective matter. If you are a strong guy with a strong kick then you will definitely prefer and need a stiffer blade.

However, a smaller diver with less strength in the kick will need a less stiff blade. That is not to say that this diver couldn’t deal with a stiff blade. The stiffer blade runs the risk though that it wears a beginner or smaller person out.

In the end for the beginner or recreational diver it comes down to getting a somewhat less stiff blade. Most of the standard fins you can find online will suffice. You won’t run into any issues with fins from any of the best dive gear manufacturers.


There are plenty of choices when it comes to fins. If you are a recreational diver or just beginning with the sport then you actually might have the least issues finding fins for yourself. Stick with the readily available and highly rated fins and you will have many enjoyable dives ahead of you!

No matter what kind of fins you get, make sure that you mark them with a waterproof pen. You might be surprised how many divers will have the same fins as you do when you go onto a dive boat. And you definitely want to be able to end up with your fins again.

If you get open heel fins then make sure that you also buy replacement straps. It’s a good idea to have them with you and available when you dive as you never know when your straps might break. As luck has it, they will usually rip at the worst time and you’ll be glad that you can instantly replace them!

Select highly rated brand name fins that you can get online and you should end up being fine. We would suggest that you pick open heeled fins and if you just start with the sport or only dive once in a while then stick to blade fins. Split fins are great but do require some more experience.

The i3 system to inflate or deflate the Axiom is a unique system. It combines the usage for inflation and deflation into a single lever. It is positioned on the side where you can easily reach it.
