Shearwater Research are renowned for their dive computers, and with the Teric, they have targeted the wristwatch-style market. In short, the Teric has all the features divers have come to love in the company’s computers – and more. It has four buttons rather than the usual two, but Shearwater have applied situationally adaptable logic to their menus and buttons, making it easy to figure out.

It also comes with a wirelessly rechargeable battery, and it has tech, OC tech, CCR and freediving modes.

First things first, let’s talk about how this thing garners plenty of comments. This is down to the ridiculously bright display in ‘watch’ mode – never mind the diving side of things, this makes one very appealing watch! I especially like the fact that it has three means of displaying the time – a ‘normal’ digital display, a digitised set of traditional ‘hands’, and my personal favourite, a moving ball with the time in, that has a smaller ball travelling around the outside of the face showing the seconds. You can then also opt in any of these modes to show the remaining battery life and also the date, as well as variations on the basic display. Extremely clever and it really allows you to personalise the Teric in day-to-day use. There are several vivid colours to choose from, but I like the vibrant green, which is named ‘Predator’ for obvious reasons.

That display also kicks in underwater. After just a handful of test dives, I was awed at how bright that display is – I can see why Gabriel from Shearwater described the Teric as being ‘like the sun’ compared to the Perdix being ‘like the moon’…

The downside of that display is that it eats battery life when on full brightness, but as it is rechargeable, it is no drama. To charge the Teric, you just pop it in its little cradle. If it is seated correctly, the light on the front goes green, if it is wrong, it flashes red. Once it is charged, it flashes green. Simple! And the display even changes orientation in the cradle so you can use it as a desk clock!

I was already a Shearwater Research fan from my Perdix AI, but I really enjoyed using this wristwatch-style computer. I just can’t get over how clear the screen is – despite being more-compact than a Perdix, for instance, it is just as easy to read. It was clear to read even in the shallows when the sunlight was extremely bright – some full-colour computers can struggle in bright sunlight. And it is nice knowing you always have your dive computer on your wrist for when you need to get in the water. 

The Teric accompanied me to Sudan for a liveaboard trip, and it performed faultlessly all week. I had my Perdix AI on one wrist and the Teric on the other, and it was amazing how bright the Teric is compared to its big brother. As well as the clarity of the display, I also like the logbook on the Teric, which clearly shows all your dive data, especially the graph of your dive profile. 

The Shearwater Research Teric is easy and intuitive it is to use. Take the menu, for instance. You press the bottom left-hand button to enter, and then it clearly shows you on screen which buttons scroll up and down, which ‘enters’ the next screen and which takes you back to the previous section. Fantastic, no random button pressing!

And I am increasingly becoming a fan of the vibration function. That little buzz when I end my safety stop is great, especially if you are faffing with your camera or getting engrossed in the reef.

The Shearwater Research Teric looks good in an understated way, it has a nice solid feel to it, and that screen is just so unbelievably bright. A supremely well-specced and competent computer.

I have a Teric, and agree it’s a great dive computer. However, there is one thing I would really like to see changed. If the Teric is not charged for a certain period of time the battery will completely discharge and need to be replaced. The battery can only be replaced at authorized Shearwater service centers, these centers are not on every corner. In the end I imagine the cost will exceed $150, to have the battery replaced.

I’ve had my teric for 4 years now and have used it on 100 open circuit and 100 closed circuit rebreather dives.
I use 2 transmitters linked to my Teric to monitor my gases and solve the compact design.
The only problem is the battery life.
After 2 years the battery would only hold its charge for 1 week. I had it replaced under warranty but within a year I had the same problem. I now need to charge before every diving day.
The good thing is that I can charge it wirelessly off my Samsung phone.

May I ask. Would you buy another if you needed a new dive watch

As a dive computer, it does everything that I need.
I wouldn’t hesitate to buy it again if the need ever arises again.
