The Shearwater Teric Dive Computer from Shearwater Research is a fully functional recreational, technical and freediving dive computer made with recreational divers in mind.

The Teric features open-circuit and closed-circuit Air, Nitrox and Trimix multi-gas functionality along with a three-axis tilt-compensated digital compass. It has Recreational, Gauge, Freediving, Open-Circuit Tech and Closed-Circuit/Bail-Out modes. The Teric has four buttons and incorporates situation adaptable logic menus to make operating and diving the Teric very intuitive. The Teric is also very configurable; for example you can set a button to give you a single press access to different tools like compass, stopwatch, countdown timer, etc. There are haptic (vibration) and audible alarms that can be disabled (none, either, both) to prevent annoying other divers in the vicinity.

The Teric offers an information screen utilizing a {1.39 in | 35 mm} full color AMOLED display with a { Diameter x Height | 55mm x 18mm } body and { 4.25 oz | 120.4 g } weight. Brightness levels are user adjustable and accessible with just one button press. During a decompression dive, the Teric provides complete information displays of all required stop times. The Teric can provide time-to-surface based on “look ahead” at planned gas switches. Multiple gas definition presets are supported with any combination of oxygen, nitrogen and helium. The Teric will NOT “lockout” after a missed stop or ascent rate violation. After the dive, the Teric communicates via Bluetooth to connect with the Shearwater Cloud dive log manager, which is compatible with MS Windows, OS X, iOS and Android devices, supporting wireless log downloads and firmware updates.

The Teric supports hoseless gas pressure integration, sometimes called air integration (AI). The Teric is capable of wirelessly connecting to either one or two optional transmitters giving the diver ability to monitor up to two tank pressures. It is also capable of calculating the Gas Time Remaining (GTR) on one assigned tank. Air integration is optional for all modes, from OC Rec to CC/BO. The tank pressure(s), in PSI or BAR, and GTR can be displayed to the customizable slots on the main display screen or accessed through the underlying information screens.

The Teric base price does not include a tank pressure transmitter because the consumer may not wish to use the AI feature or may already own a compatible transmitter. Shearwater Research tells us that as long as the transmitter is marked with “FCC ID MH8A” on the body then the transmitter, regardless of the brand, will also work with their Teric, Perdix AI and NERD 2 model air integrated dive computers.

The Teric has been designed with a wireless rechargeable battery and includes a wireless induction charger stand. Typical dive time on a single charge is at least 30 hours and as much as 50 hours, depending on the features enabled. The expected life of the built in battery is five (5) years and the battery can be replaced at one of the Shearwater factory authorized service centers. Although Shearwater recommends using their charging stand, the Teric can also be charged by the flat mats that support the Qi wireless-charging standard (which includes the latest iPhones and many Android phones.)

The Teric also comes with a nice Shearwater Research branded zippered “travel” case.

Additional options include user changeable dual color wrist bands in Blue, Green, Pink, White, or Yellow; along with additional charging stands.
