10 Best Dive Computer Watches of 2022

Having been around since the 1980s, dive computers are a must-have piece of gear for every scuba diver. 

Diving tables and dive watches were used to plan and conduct dives safely before dive computers were available – tables were used to calculate the no-stop bottom times for recreational dives at various depths, while watches were used to keep track of these times underwater. Since dives were planned in advance, the planned bottom time could not be altered mid-dive, even if the diver spontaneously ascended to shallower depths. 

Despite the fact that dive computers have largely replaced dive tables and watches, some people still like to wear dive watches as a backup (or for style!). The reason is because dive computers display the time, can be read in the dark, and are water-resistant, just like dive watches do. 

However, dive computers also give you a lot more information about your dive, such as depth and temperature, and they can store information about your dives.

A dive computer is built on the same algorithms as a traditional dive table, but it continuously recalculates the remaining bottom time as you dive deeper. As a result, divers can extend their bottom time by shallowing up mid-dive, which is a huge advantage over traditional planning.

It’s not to say you should stop planning your dives – most dive computers have integrated planning features – it’s just that once you are down, you have a bit more flexibility.

Because dive computers are so convenient and informative, it’s no wonder they’re taking the world by storm. But due to their surge in popularity, dive computers are now available in a wide range, and no two are quite the same. In fact, dive computers differ greatly when it comes to factors like size, usability, and, of course, price. Furthermore, there are dive computers for beginners, advanced divers, and professional or technical divers.

There are quite a few things to consider before picking out your dive computer so, to make it easier, we’ve put together a list of the best dive computer watches currently available.

8 Best Dive Computer Watch Reviews

1. SHEARWATER TERIC

SHEARWATER TERIC

The Shearwater Teric dive computer is no exception to the Shearwater reputation for providing high-tech features. 

The Teric can be used with air, nitrox, and trimix blends, and can handle up to three gas switches per dive. It is also capable of setting a closed-circuit or bailout mode. The Teric’s air integration feature enables monitoring of up to four air supplies at the same time. However, unlike most technical dive computers, the Teric resembles a small watch.

Its bright, segmented display aids visibility, and its interface can be customized to give you the information you want (and you can even customize the color scheme). Shearwater Perdix’s dive log capacity is slightly lower than most computers, but at 500 hours, it’s still a good choice. Furthermore, unlike the Perdix, the Teric has a freediving mode, which makes it a great choice for water babies in general. You can transfer data wirelessly and choose from multiple languages thanks to Bluetooth compatibility. 

Technical dive computers may sound appealing, but if you’re put off by their size, the Shearwater Teric might be just right for you.

2. SUUNTO D4i NOVO

SUUNTO D4i NOVO

Its great balance of style and function make the Suunto D4i Novo a timeless classic in the scuba community.

It is a great choice for dive professionals because of its small dimensions, variety of color options, and minimalistic design, making it an excellent choice for day-to-day wear. We like how you can choose how long the backlight stays on after using the display, despite its small size, and it is easy to read. 

The 4 buttons make navigating through the menu a breeze, and there are three modes to choose from: air, nitrox, and freediving. Moreover, it features several safety features such as the option to stop deep and audibly when you ascend too rapidly (don’t worry – the sound can also be turned off). The air integration feature allows you to keep a close eye on your air supply, and it can handle up to 3 gas mixtures per dive, as well as blends containing up to 50% oxygen.

Although you cannot change the battery at home, Suunto is highly efficient at replacing and repairing parts, and the battery should last at least for a few years. You will need to purchase the connecting cable separately if you wish to access your dive data on a laptop or other device.

In summary, if you want a dive watch that you can wear every day, and is a step above beginner models, the D4i is a great choice.

3. GARMIN DESCENT MK2i

GARMIN DESCENT MK2i

It’s possible that the Garmin Descent MK2i will be right up your alley if you want a computer that can track dives, runs, swims…and pretty much anything else.

Almost all of the dive watch features you could ask for, including nitrox, trimix, closed-circuit rebreather, as well as apnea and spearfishing modes, are available in the MK2i. The 1.4” full color display is highly customizable, so you’ll see what matters to you in each mode.

Furthermore, unlike most dive computers, the MK2i has an in-built GPS function that allows you to pinpoint your dive entry and exit points, as well as an underwater compass, making it ideal for mapping dive sites, conducting research, and finding lost people. If you choose the MK2i (rather than the MK2), you also have to monitor up to five tanks for air pressure.

Besides running, biking, surfing, hiking… and pretty much anything else, the MK2i is also great above the water. The MK2i not only tracks your routes, but it can also keep track of your health as you train so that you can track your progress, and it will even tell you what time is best for you to train. In addition, it can be preloaded with maps, trails, and workouts so you can use them while traveling.

You can even load up to 2,000 songs onto the MK2i and stream music, monitor your sleep, daily stress, and respiration, and even send your location to the emergency services in case of an emergency (but not while you’re diving).

It is not possible to change the battery yourself at home, but you can recharge it, so you shouldn’t need to replace it for years. The Garmin Descent MK2i is a truly unique dive computer that’s perfect for sports enthusiasts of all kinds (via Bluetooth).

4. SUUNTO ZOOP NOVO

SUUNTO ZOOP NOVO

Suunto has been manufacturing dive computers for years, and the Zoop Novo is one of the best.

With the Zoop, you will know the time, temperature, and depth of your dive as soon as you begin your descent, which is great for dive planning. 

Although the ascent rate and profile are highly conservative, this is a great way to get into good diving practices (as well as making sure you stay safe!) from the get-go. It is large enough to wrap around a drysuit, and the strap can be folded back on itself to prevent it from flapping when worn in a wetsuit.

My Zoop lasted me all the way from a total beginner to a diving professional, so it’s highly durable and likely to stay by your side as you progress from a beginner to an advanced diver. It’s also great that you can replace the battery at home when it’s time (but it won’t be for a long time). It does have nitrox mode, but does not have other advanced features, such as integrated air options, so it is best used as a backup computer (rather than a primary one). 

The Zoop is also very affordable, and it has a freediving mode as well, so you’re getting two for one. Finally, if you like getting your geek on and checking out your stats post-dives, you can connect this computer to your actual computer via USB (but the cable will cost extra). 

There is one major flaw of this easy-to-use, durable computer – its size – it can be read easily, but is far too bulky to wear as a day-to-day watch. If you can see past that, the Suunto Zoop Novo has a lot to offer.

5. SHEARWATER PERDIX AI

SHEARWATER PERDIX AI

In terms of technical dive computers, the Shearwater Perdix AI comes out on top thanks to its impressive display, customizability, and wide range of extra features.

The screen is not only extra big, it is also colored and you can adjust the brightness to your liking. Perdix is compatible with nitrox, three blends of nitrox per dive, trimix, and closed circuit systems, and the information displayed depends on the mode selected. You can also connect up to four transmitters if you choose the air integrated model, no matter what mode you choose, which is great for monitoring students as well as diving with multiple tanks.

It’s surprising to learn that the Perdix is powered by AA batteries, even though it has a lot of technical features. The batteries can be replaced at home, they’re easily accessible, and the display even shows the battery level so you won’t ever run out. For emergencies, you can carry a few spares for the transmitters because they also run on CR2 batteries.

It couldn’t be easier to access your dive data – simply pair your device with the Perdix via Bluetooth so you can download any information you need. And don’t worry if you’re forgetful, the Perdix has a 1000-hour memory.

Although the Perdix is too large for a regular watch, it does not come with a freediving mode either. The large size is a huge plus for most people, and there are plenty of other modes, so the absence of a freediving mode is acceptable. You can, however, check out the Shearwater Teric if these are your biggest concerns – it’s got all the techy features packaged into a wrist-mounted package with a freediving mode.

6. MARES QUAD

MARES QUAD

Are you tired of spending precious time underwater squinting at your dive computer? Look no further than the Mares Quad!

The Mares Quad dive computer boasts an extra-large screen, incredibly clear display, and bright LCD backlighting. 

You can even get your bottom time down to the second with the segmented display, so you don’t miss anything. Switching between modes, planning your trip, and viewing your log are all easy with the four buttons on land. Moreover, the top two and bottom two function the same way underwater, so navigating is very easy regardless of which wrist the computer is on.

This quad is nitrox-compatible, and you can use up to three gas mixes per dive. It’s easy to change the battery at home, and the power indicator keeps you in the know. Also, we like that there are standard and air-integrated options, so you don’t have to pay extra for things you don’t need.

As the screen is so large, all of your logs can be viewed directly from the computer itself, but if you need to transfer your data, a cable or Bluetooth can be used. It might not be your primary reason for choosing a Quad, but we like the fact that it comes in a few colors.

It’s not designed to be worn as a watch on a daily basis, but if you’re looking for a computer with an excellent display and great value for money, the Mares Quad might be just the thing for you.

7. AQUA LUNG I470TC

AQUA LUNG I470TC

Our recommendation for the Aqua Lung i470TC is convenience.

Since it’s so compact, you can wear it as a regular watch as well, so it’s super convenient if you’ll be on and off the boat all day. In addition, the watch’s small size has kept the weight low, making it an ideal travel companion for divers. If your battery dies mid-trip, you can take a spare with you – it’s user-replaceable, so you don’t have to worry.

The i470TC’s small dimensions have reduced the display size slightly, but thanks to its intuitive layout and access to your dive log with just a push of a button, it is still easy to use. Aqua Lung’s dive log app and Bluetooth connectivity make it easy to connect this computer to a laptop, phone, or tablet to view your profiles on a larger screen. It is a good idea to backup your dives every now and then if you are a big diver log keeper. Because this watch can only remember 24 dives at a time.

This i470TC doubles up as a freediving computer, and it’s nitrox compatible too. In addition, it supports air mixes containing up to 100% oxygen and allows three gas switches per dive. Besides being air-integrated, you can use it with up to three transmitters, so instructors can keep an eye on their students’ air supplies with ease.

The Aqua Lung i470TC ticks all but the most technical boxes while remaining compact and convenient.

8. CRESSI LEONARDO

CRESSI LEONARDO

The Cressi Leonardo is an outstanding dive computer if you want an easy-to-use, reliable device without spending a lot of money.

The Leonardo is catered to beginner divers and is extremely easy to read and use. The large screen is segmented to aid readability, and the single-button interface makes selecting modes very easy – even when wearing gloves. Despite the fact that the LED backlight automatically activates when safety alarms sound, we wish it were a tad brighter. In addition to safety alerts such as missed safety stops, rapid ascents, and oxygen toxicity, the computer is great for beginners in scuba diving.

The Leonardo is also extremely rugged, making it extremely popular among rental stores as well as people who don’t like to be precious about their gear. Considering how durable this computer is, you’ll likely use it as a backup computer years from now. You can also easily replace the battery at home when it’s time to do so, so you don’t have to pay a replacement service when the time comes.

You can share the Leonardo safely with your family or friends if they dive after you, since the Leonardo can be wiped after each dive. The Leonardo can store 75 hours of dive information that you can access from the screen or via a laptop – but you have to buy the download kit separately, and it’s not the cheapest we’ve seen.

This dive computer lacks features like air integration and multi-gas compatibility (although it does have nitrox mode), and it’s too bulky for day-to-day use. If you are looking for something rugged and reliable, this is a great choice.

BUYING ADVICE FOR DIVE COMPUTERS

Our list of the best dive computer watches is complete. In case you’re still unsure which one is right for you, here are a few things to keep in mind when you’re shopping around. As you can see, they vary a lot when it comes to price, size, and extra features.

Gases

AIR: All computers have a standard air mode. In this mode, your no decompression limit is calculated based on the assumption that your tank contains normal air (just like the air we breathe on land) and your depth.

NITROX: Nitrox blends contain more oxygen and less nitrogen than regular air. With less nitrogen in the mix, divers can dive deeper before reaching their no-decompression limit (yay). It also helps some people feel less tired after diving, especially older people or people who dive multiple times a day. 

There is a risk of oxygen toxicity, however, due to the increased amount of oxygen in the tank. Nitrox-compatible computers calculate this risk using the proportions of each gas (which you enter manually). 

The majority of dive computers aimed at intermediate-level divers are able to handle blends of up to 50% oxygen, whereas recreational divers typically use blends containing either 32% or 3% oxygen. Using higher bends will require your computer to be compatible. 

TRIMIX: A trimix-compatible dive computer keeps track of both your no decompression limit and oxygen toxicity, just like nitrox-compatible dive computers. But they base their calculations on oxygen, nitrogen, and trimix proportions. 

As helium reduces nitrogen and oxygen’s effects at depth, trimix is popular among technical and commercial divers (though most recreational divers won’t use it).

MULTIPLE: A few computers also offer the option of switching gases during a dive. The switch is usually done on the ascent, when divers breathe oxygen-rich air to reduce their decompression time. While recreational divers won’t use this feature, technical divers will.

Modes

WATCH: As for this one, most dive watches can be used as regular watches on land, although you will probably only want to do this if your computer is fairly small. 

FREEDIVE: While not an essential feature in a dive computer, this is an awesome feature for freedivers as well as scuba divers. This mode allows you to track your progress while also helping you freedive within safe limits by monitoring your depth. Make sure your computer is switched back to the correct mode before every activity, otherwise it will not be happy (or helpful).

GAUGE: It displays your depth, and usually the time, but doesn’t show additional information that may be relevant to you, like the bottom time or no-decompression limit. Computers in this mode are usually used for backup purposes only. 

REBREATHER: There are some dive computers with a rebreather mode (or closed-circuit rebreather mode, CCR) that allows you to set low and high levels, but most recreational divers will never use it.

Battery

REPLACEMENT: It’s not uncommon for dive computers to come with decent batteries that will last you for a few years even if you use them often, but eventually they will need replacing. It is possible to replace some computers at home, while others require specialist replacement. 

You can take a spare battery with you on your diving adventures if you’re diving in remote areas, which can be very handy if you’ll be diving in remote areas. User-replaceable batteries also save you time and money when diving. It is still wise to have your batteries replaced professionally so that your warranties remain valid (if you make a mistake, you will not be covered).

RECHARGEABLE: Although rare, there are some dive computers out there with rechargeable batteries. These mean you don’t have to wait (or pay) for your computer to be serviced by an expert, and you don’t have to worry about making a mistake either. Rechargeable batteries are primarily found in high-end diving computers at the moment, but their popularity is rising, and they may soon be integrated into budget dive computers.

Extra Features

AIR INTEGRATION: With the aid of a transmitter connected to your regulator’s first stage, dive computers that are integrated can display how much air you still have left in your tank. Additionally, you can monitor the air supply of several tanks by pairing your computer with multiple transmitters. 

This can be very useful when you’re guiding or teaching small groups of divers, because you’ll be able to see directly how much air they’ve left – but be aware that you need to be near the divers to use this feature. Also, check out how many transmitters your computers can pair up with – for some it’s just one, while others it’s four. Air integration is also handy for people who dive with multiple tanks, like sidemount divers. 

In many dive computers, you can choose between air integrated and standard models, but in others, you have to choose. Air integrated models will cost more, and you’ll have to pay more for the transmitters too, so you should only invest in them if you’re planning to use them.

CONNECTIVITY: Those who want to log their dives can do so by navigating through their computer’s menu to find their recent dive history. 

Some people prefer to look at their dives in detail on a larger screen, so they can do so. A few computers have USB cables that allow them to transfer data to other devices, while other dive computers send dive data via Bluetooth instead of wires. If you want a computer with Bluetooth compatibility (usually the cheapest ones aren’t), you might have to pay a bit more for the cables. Again, consider how important connectivity is to you!
