The G1 Solar represents a big step forward in both longevity and daily wearability compared to their previous Mk2 models- though this comes at the expense of some significant features.

The Shearwater Teric is Shearwater’s first foray into a watch-sized dive computer. Don’t be fooled by its small size, the Teric is a full spec, no-nonsense technical dive computer that’s suitable for the most serious tech diver thanks to its many added extras.

It has all the modes you want, including recreational and even freediving. Unlike some computers, the freediving mode hasn’t been added in as an after-thought, instead, it’s designed to meet the needs of even high-level competitive freedivers.

It also looks good out of the water as a very stylish watch that wouldn’t be out of place in the boardroom.

Specs & Features

  • Bright full-color 1.39in/3.5cm AMOLED display
  • Stainless steel bezel and sapphire crystal screen
  • 200m/650ft crushproof
  • Five configurable dive modes
  • Two adjustable layouts for each dive mode

We went diving with the new Garmin Descent Mk2i. This is a cool dive computer with a user experience that was clear to see and use before, during and after the scuba dive. The amazing multi-sport functionality is truly impressive – both for the amount of activities and the depth of info.

Backcountry skiing, sailing (with integrated tide charts), skydiving and kayaking are some of the crazy amount of activities this machine is designed to track.

Expectations were high after the success of the original Descent Mark One, which seemed to come pretty close to hitting the sweet spot between a dive computer and an everyday smartwatch. The upgraded functionality to the Mk2i both as a dive computer and as a multisport smartwatch overcame our initial skepticism.

The bling in the Mk2 is the addition of the SubWave network on the Mk2i (the “i” stands for integration), a sonor-based communication technology that increases range and signal strength underwater. This revolutionary system pairs with the T1 transmitter providing advanced air integration and ultra accurate air pressure of up to 5 gas-mixed tanks (ni-tri- and 100%-ox), dive time remaining, and consumption rate.

What’s amazing is the ability to read the same data on other scuba divers within a 10 meter range. An instructor might like to know their students’ time remaining while underwater, but this info is generally more interesting for post-dive deep-diving.

With new decompression and safety stop upgrades to better provide fast and accurate info for ascending, the Mark 2 improves diver safety.

Specs & Features

  • Advanced, watch-style dive computer with 1.4” color sunlight-readable display (36% larger than previous model)
  • Six dive modes as well as multi-GNSS support and ABC sensors — including an underwater compass — know every part of your dive from entry to exit (GPS tracking does not work underwater)
  • Enhanced wrist-based heart rate estimates and Pulse Ox
  • Lets you store and review data from up to 200 dives right on your wrist and share and review dives in the Garmin Dive app downloaded to your paired compatible smartphone
  • Battery life: up to 80 hours in dive mode, up to 16 days in smartwatch mode and up to 15 hours in GPS mode with music

If you follow any scuba forums or diving groups on Facebook, you have no doubt noticed that the same questions keep being asked and answered.

Backplate or wing vs. jacket style BCD, longhose or not, for or against snorkels and so on.

With similar regularity divers will be asking about which dive computer they should purchase next, and almost instantly someone will chime in with a suggestion for a Shearwater Perdix.

It’s so prevalent in fact that memes have started appearing about it in diver’s groups.

Shearwater has quickly earned a reputation for producing reliable and user-friendly dive computers of the highest quality. The company’s initial focus was on gadgets for technical divers, such as trimix computers and electronic boards for rebreathers,

But Shearwater has definitely turned its attention to the recreational dive community. The Peregrine computer demonstrates this focus.

Specs & Features

  • Display: 2.2 inch (5.59 centimeter) customizable and full-color LCD

Two huge features stood out to me when I picked up the Petrel. 1) The AA battery option makes my save-a-dive kit much easier to maintain. I use rechargeable AA’s which further decreases my cost of having to replace. 2) The 1000 hour memory is amazing. I use this computer for work and play, but being able to record every dive makes sure I am covered and backed up if there are ever any questions or issues with work. Diving with the computer is beautiful and easy. The large and bright screen never leaves me guessing on my air or dc times.

Dive computers have revolutionized the way we dive. Gone are the curious days of seeing struggling dive guides attempting to use the PADI Wheel at depth!

Combining depth sensors, timers, detailed decompression status, ascent rate alarms, and even more features, dive computers take away the complicated calculations, allowing you to get on with looking at the fishes, wrecks, and reefs.

One dive computer that has stood the test of time is the ever-popular Suunto Vyper. Suunto’s newer issue is the Vyper Novo, a hardy computer that can take a few knocks and still be reliable dive after dive.

  • check-markIt doesn’t have the sleek watch-like design of some of its competitors. Although Suunto does produce models that you can wear to the bar, we happen to like a computer that is functional and large and perfectly made for the time spent under the waves

Last fall Garmin made waves in the dive world with the much-anticipated release of their Descent Mk2 – a crossover smartwatch and dive computer that could stand on equal footing with full feature dive computers and multisport smart watches alike. Their freshly announced Descent Mk2S brings all of the features we loved about the Mk2 translated into a smaller interface for women and people with smaller wrists. The Mk2S is all about giving divers more options. With an expansive color palette, several band options, and features built specifically for women- you’re getting far more than most other dive computers could ever offer you.

Specs & Features

  • Compact 1.2in display
  • Fully-featured dive computer
  • Multisport tracking and advanced training metrics
  • Wellness tracking and health monitoring
  • Three colorways with interchangeable bands

The Descent MK1 has made a splash in the dive industry. Garmin, a company dedicated to precision outdoor and marine technical equipment, released the MK1, its first dive computer, at DEMA to rave reviews.

The computer is designed to look like an everyday watch but packs a punch in terms of features and functionality. Suitable for freediving and both recreational and technical scuba diving, the Descent MK1 may not be the cheapest dive computer on the market but it does perform.

Garmin has taken its knowledge of environmental measuring tools and combined that with an all-in-one, full-featured dive computer. The company has even included elements of wearable tech by including a heart-rate monitor.

Specs & Features

  • Full in-computer plan mode for both recreational and technical dives

Here are a few Common Features you’ll like about your dive computer:

It’s on my wrist

Actually my first computer was built into my console, but that’s not so common these days. It is a lot easier to look at my wrist to get information about my depth and bottom time than to have to bend down and check my gauges all the time.

Heck, some computers even replace all your gauges and console entirely.

Having mine on my wrist means I tend to look at it a lot more often too. Some computers are even built into masks, giving you a heads-up display so you don’t even have to look at your wrist. Another win for streamlining!

Constant recalculation

Tables assume that you go straight down and stay at that level (or series of levels) for the time you planned exactly. But what if you spend a lot of time looking at a turtle at 18 metres (60fsw) and spend half the time at 24 meters (80fsw)?

It seems like a small thing but your computer will tell you how much more (or less) bottom time you will get and change your dive plan as you go.

Nitrogen Exposure

Your computer does not simply let you know the bottom remaining time for the current dive. It will also let you calculate your surface interval and plan your next dives.

A table does this great when doing only a few dives, but when you are doing a lot of repetitive diving every day you have to remember you still might have nitrogen in your body the next morning.

I never seriously thought about the 10 hour ‘surface interval’ I did overnight until my (then new) computer told me I was starting my first dive in pressure group ‘C’.

Logging

Your computer will remember details about your last dives just like a logbook.

This is great for people like me who don’t like to get their logbooks wet and prefer to write it all down with a beer at the end of the day.

Some will even connect to your computer, automatically filling in an e-logbook and giving you detailed graphs and statistics.

Alarms

There are various alarms that you can set on some computers to let you know when stuff happens.

I never want to hear the 5 minutes of bottom time remaining alarm, but it has been helpful sometimes when I was distracted. I use my safety stop one a lot, which I have set to let me know when I get to 5 meters (16fsw) and then counts down 3 minutes.

I also find the rate of ascent alarm useful, which lets me know when I am going up too quickly. This is especially good when I am teaching students to do a controlled emergency swimming ascent “if you start to hear beeping, slow down”.

It tells the time

Yep, whether I’m timing a student breathing from a free flowing regulator or trying to figure out when the bar will close I know my dive computer is there.

Not all watches work very well when regularly exposed to pressure at depth and not all computers can be worn around town. Is it useful to you having one device that does both?

Other Features

Air Consumption

Some computers wirelessly connect to a transmitter in your first stage and can give you information about remaining air pressure.

They will also tell you how quickly you are consuming your air and will calculate how much time it will take you at your current depth before you use it up.

Gas mixes/Oxygen Exposure

Another great feature available on some computers is keeping track of different gas blends and oxygen exposure when diving with enriched air and Nitrox. Some will even manage multiple blends and allow you to switch between them during a dive.

Compass

Some computers have an electronic compass.  They are supposed to be a little less sensitive to having to be perfectly level and can remember headings for you. I have heard mixed opinions about how useful and accurate they are.

Some computers have built in GPS allowing you to tag a specific coordinate to navigate towards – such as your dive boat.

User replaceable battery

Does your computer have to be sent in to a dealer to have the battery changed? These computers will cost you a bit more in the long term as you will have to pay each time.

If you’re not near a service shop when the battery goes be prepared to live without it for a little while whilst you wait.

Choosing your computer

Computers come in all sorts of shapes and sizes, have different features and big cost differences.

In some parts of the world they can be a status symbol (like the sexy Suunto titanium range) and in other places they almost never see them.

I always read reviews and talk to people about their equipment before buying anything. Think about whether looks are important, what features you need, how often you will use it and how much you want to spend.

Safety advice

Remember that your computer is only accurate about your own dive. Your buddy might go a little deeper or enter the water sooner than you. Always use the most conservative computer and have a backup plan just in case.
