Shearwater Research Teric Color Wrist Dive Computer

The Teric is our third dive computer. It is a game-changer. I was using an Oceanic Atom 3.0 -- nothing wrong with it all, and my wife was using a Oceanic VT 4.0, both AI. However, my wife was having difficulty reading the numerals as she uses reading glasses. Enter the Teric. She saw a fellow diver's on a live aboard, looked at it underwater and could clearly see the numbers on the display, the colors of which can be changed to many other colors. So I bought one for her. Then when I saw it, I had to buy one for myself too, so I wouldn't have equipment envy for our month long trip to the Red Sea. Having used it for a week of diving -- about 33 dives so far, I can safely say that this is a game-changer.First, the display is fantastic, with a "big" display which shows three rows of info, or "standard," which shows four rows, two of which are customizable with different info. She could easily read her computer underwater, and she changed the different information from standard white to purple, green and yellow. the brightness can be adjusted to high, medium, low or off. Night dives, low or medium was great. Day dives, I found medium was great, although she liked high. AI was a snap and it paired with my Oceanic transmitter with no problem. The watch face is also customizable with different displays and colors.Second, the menu settings are a snap to set. Tired about digging through all sorts of obscure settings to change your gases from air to nitrox? No more. The menu settings are intuitive, and you just scroll to gases, where you can program up to five different gases and with between them. Piece of cake. I set one on nitrox 32% and one on air at 21%, and it is a snap to switch between them. I also love the fact that it is easy to change what is displayed on the home screen and in what colors, although it is simple to scroll underwater between the five screens and get as much info as you could ever want underwater. I also turned off the beeping alarm and just use the vibrate, which was nice and strong, especially for the safety stop. Nice feature is that it clearly displays "safety stop" in green and if you drift lower than about 23 ft., it pauses and then resumes when you ascend a little. I also like how it displays "safety cleared" in blue when finished -- just cool little features. I also like that it displays ascent rate numerically and in arrows, which change to yellow and red if you are ascending too fast. Again, a nice little touch. I customized the standard display to show the time remaining underwater, which I use to additionally monitor my air consumption, although you can also display air consumption as PSI per minute as well. You can monitor both your and your buddy's air as well as it will track two transmitters at once. There are many other features for the rebreather and tech diving set, but I don't need those. One chard lasts about two-three days of 4-5 dives a day -- about four or five hours of diving and surface time. It comes with a wireless charging cradle which can give a full charge in 1.5 hours on "Quick Charge" and 4 hours or so on regular charge. There are many other features to this fantastic dive watch, but those are the key ones that I have used to date. Note that according to shearwater, it already has a scratch guard installed. In fact, the only thing that I did not absolutely love about this with was that it displays "TTS". which is "time to surface," which to me is a completely worthless statistic, but cannot be moved from the home screen. Minor.The Shearwater comes with its own dive log software which pairs over bluetooth with the dive computer and downloads the info to your laptop or phone. It has a few bugs that could be better, but you can simply and wirelessly get all of your dive information, take notes on the dive, problems that you had, etc. You can also export those files to Diverlog, but I haven't tried that yet.All told, it is a pricey computer, but color display, menu, ease of use . . . Let's face it. Your dive computer is the most important part of your gear, and the Teric is the most amazing and well thought out dive computer that I have seen. I highly recommend it. I haven't dropped mine, so I can't opine on it's durability, but after 30 dives with it, both of us are in love with our new Terics!

For over the last year, I have been diving with a Shearwater Perdix AI as my primary computer. Love it, love it, love it. Especially as my close vision has been worsening with age. But, I agree with and believe the warning in the manual - your computer will fail, not a matter of if, just when, which really underscores the need for a secondary computer.Also, I often need a watch when I'm on dive trips, and well, the Perdix, though a great computer, just lacks the form factor for daily wear. Enter the Teric. I had read the reviews, but honestly, I was a little dubious. In the end, I am more convinced that Shearwater makes really great products.The Teric is a wristwatch sized dive computer that can be worn daily without looking totally looking like a dive computer. It isn't small, but about the size of a men's watch. For those that know the Garmin Fenix, the sizes approximate. Menus are intuitive and switching between watch mode and dive mode are pretty easy (in fact, they were at times reminiscent of navigation with the Garmin Fenix). The screen is crisp and clear, and surprisingly, while smaller than the Perdix text, I had no problems reading the display underwater. The diving models used are the same as the Perdix, as well. I also liked the new audio and haptic alerts on the Teric.Incidentally, no product is ever perfect. I found adding EANx percentages a bit of a pain, but not so annoying to stop using the watch. Once programmed, this isn't so much of an issue. Haptic and audio alerts could be a little stronger. I could see anyone wearing more than a 5 mm suit likely having issues feeling vibration. Would love audio alerts to be more unique because nothing is more annoying than hearing a beep and trying to figure out if it's your computer or someone else. Charging works really well most of the time, but there are times when I seat the watch in the charger and nothing happens. This just means I have to be a little more mindful about putting the computer in the charger. Love quick charging, though. As for case durability, the watch casing seems fine, but it'll take some time to determine band durability.

Having logged 70+ dives now in various water conditions I can say the Teric is about as good as it gets for a no nonsense dive computer that isn't as clunky as some other models out there which could compete on a similar functionality level.The combination with the transmitter makes diving both from a safety but also logging perspective a "joy". The Shearwater app makes it incredibly easy to sync the watch alongside the transmitter data into your digital logbook for further use and analysis.The computer itself is very intuitive as it relates to setup and usage. The display is easy to read and organize as well as very bright under water so not issues looking at all your dive data even while in the deep or rather darker caves etc.Switching between different gas mixes is equally easy done. In addition personally prefer the rather conservative algorithm calculating NDL etc. while diving.The computer also allows easy pairing with two transmitters at the same time which is a major upside when heading to more challenging dives with you buddy.Overall very happy with the purchase and can highly recommend both devices.
