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.

In 2010 Suunto released the Zoop, which went on to become one of the world’s best-selling entry-level dive computers. The Suunto Zoop Novo is the successor to the popular model. Similar to the original but with added capabilities, the Zoop Novo is sure to keep Suunto at the forefront of the market.
Already know the Suunto Zoop Novo is for you? If so, click on the link above for the latest prices and all the details. If not, read on to find out if the Zoop Novo lives up to the standards set by its predecessor.
Specs & Features
- Five modes: off, air, Nitrox, gauge, and freediving
- A built-in dive planner
- Full continuous decompression algorithm
- Innovative timer for freediving
- Timer in air and nitrox modes
Our Overall Review
Reasons to buy:
-
Big, clear display
-
Simple and easy to use so ideal for divers of all levels
-
You can change the length of time the backlight stays on
-
The price point makes it an ideal back-up computer
-
Personal dive profiles allow you to change the algorithm to be more conservative
Reasons NOT to buy:
Although the screen is large and easy to read, the Zoop Novo can’t be worn as a wristwatch, unless you’re OK with its chunky size!
The USB cable has to be purchased separately.
No in-built compass.
Many customers complain about the lack of information provided in the user manual. However, a simple internet search and you’ll find the info that’s missing.
Where to buy:
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

The tank pressure transmitter had problems linking if the tank was turned on too rapidly. But this is true for many transmitters
Only available in black
No built-in compass, however, this is a mid-range computer so we can’t complain
Where to buy:
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.
Already know the Perdix is for you? Click on the link above for the latest prices and all the details. For more info, read our in-depth review of the Shearwater Perdix.
Our Overall Review
Reasons to buy:
-
Massive, massive user configurability. You can choose which elements are the most important to you. You can essentially make it the most useful computer, no matter if you dive a rebreather, dive open circuit technical diving, or just a recreational diver who perhaps dives nitrox now and then, but never aspire to dive into the tec side of diving.
-
Bright display and ruggedness
-
Innovative features and stellar customer service
Reasons NOT to buy:
Communicating with shearwater computers via Bluetooth (to download logs or update the welcome screen to a custom “Reward Given If Found – Call Joe Diver 1234-1234-1234”) can occasionally pose issues on Mac, with multiple attempts needed.
Cost (yes, you knew this one was coming)
Where to buy:
Described by Aqua Lung as having an uncomplicated, intuitive, and rugged design, the i300c is a great computer for anyone looking for an option that’s more versatile than an entry-level computer. With a great price point for the features it offers, the i300c has something for all divers. Offering gas switching, multiple dive modes, a user changeable battery, and Bluetooth connectivity, this computer certainly packs a punch in terms of features.

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.
Shearwater’s aim was to utilize many of the excellent features of its industry-leading Teric and Perdix models, but make a product that was less complex, easier-to-use, and would be appreciated by beginners and experienced recreational divers.

-
The uber attractive price point
Reasons NOT to buy:
The alarms are almost disturbingly loud
Even though this computer isn’t Puck Pro level huge, it’s still not really suitable for use as a daily watch
The strap is far too long and will need to be trimmed
The Puck Pro is Mares’ second generation Puck computer. First introduced back in 2008, the Puck impressed divers with its easy-to-use and intuitive interface. The Pro version builds upon this foundation while still maintaining a highly competitive price point.

Breaking a decompression ceiling for more than three minutes will result in the algorithm locking and no decompression information will be displayed. If a tech dive wanted to use The D5 as a backup, and the dive plan deviated from Suunto’s algorithm, an algorithm lock is not very helpful. That said, the D5 was designed to be a recreational computer.
Where to buy:
Popular scuba manufacturer Aqualung has done a great job with the i470TC dive computer. Superseding the i450T, the i470 TC is sleeker, lighter, and more eminently more stylish than its predecessor.
Aqualung has clearly listened to a few complaints about the clunkiness of some of its computers and has addressed those in the i470 TC.
The dive computer’s screen is easy to read and navigating the settings and menus is a breeze. Plus, with the ability to pair with three separate transmitters and change between three gasses, this dive computer has enough features to make it a hit.

Intuitive menu design makes settings easy to navigate
Reasons NOT to buy:
Missing a built-in compass
The strap is not as wide as many dive computers, could feel less secure on the wrist
Suunto’s D series range of computers uses the same trusted Suunto algorithms. But these computers look more like watches than the bulky bits of kit you might have previously worn. Sleek and stylish, the D series is favored by dive professionals around the world. The D6i Novo is the mid-range version, offering more features for advanced divers while still retaining usability at an affordable price.

-
Look and feel – a classic design that can be displayed in any setting
Reasons NOT to buy:
Slightly conservative interpretation of Dalton’s formula. This could be frustrating for certain divers
The anti-reflective coating on the screen is not great. On shallow dives and under bright sunlight glare is still a factor in reading the screen
The silicone strap can get a bit sweaty in hot weather
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.
Specs & Features
- Best for: Technical & Advanced
- Gases: Air, Nitrox, Trimix
- User Changeable Battery: Yes
- Features: The battery is standard AA, large 2.4″ display, bluetooth integration, Digital Compass

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.

Reasons NOT to buy:
It doesn’t have the depth capabilities as other gas switching computers but is absolutely perfect for recreational diving and up to extended range. To go deeper you would have to be looking at Trimix compatible computers
It 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
ScubaPro is one of the most recognized brands in the diving industry. From masks and wetsuits to regulators and BCDs, the company is renowned for quality products that divers around the world rely on.
Its range of dive computers is no different, with the Aladin, Mantis, and Galileo ranges all featuring reliable, easy-to-use, durable, high-performing computers. The next-gen Galileo is the G2, which incorporates everything ScubaPro customers love about the Galileo and taking it to the next level.
It’s available as a wrist-mount or console. Here we’ll be taking a look at the wrist-mounted G2 that comes with a transmitter and heart rate monitor.

Algorithm lock: If you spend more than 3 minutes above the decompression ceiling the algorithm will lock you out (and you will need to finish your deco based on tables). We want our computer to help us surface safely, not give up on us if there’s a problem!
No option for a one button press bailout on CCR
Can’t switch off deep stops when using trimix
CNS calculations give very conservative maximum depths
Heavy at 347g/12.2oz
Where to buy:
The Mares Quad was a great purchase for many divers. It’s a full feature wrist-mount computer that is affordable.

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
- Six diving modes (single-gas, multi-gas, apnea, apnea hunt, gauge, and plan)

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.

A dive computer often looks very similar to a dive watch!
It automatically tracks the diver’s time and depth on each dive. The real-time information helps to ensure you don’t dive too long – or go any deeper than will be safe, based on the diving you’ve previously done that day.
Even for beginners, it’s important to know that there’s a huge difference in dive computers and each divers personal need. You should use our guide to dive deeper into the dive computers that fit your need.
