Shearwater TERIC Computer

Full Colour. High Resolution. AMOLED.

The Teric from Shearwater Research of Canada is a full technical dive computer with recreational divers in mind. The Teric includes 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 single press access to different tools like a compass, stopwatch, countdown timer, etc. There are haptic (vibration) and audible alarms that can be disabled (none, either, or 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 transmitter may be installed directly into the first stage or installed on a short HP hose if desired. A reminder that if you are planning to use the transmitter on a short HP hose then an AIR SPOOL IS REQUIRED.

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.)

Recreational Open-Circuit Features

Key features of the Recreational Open-Circuit mode (aka Recreational Nitrox mode) include a simpler menu structure, a less cluttered display with a larger font and configurable bottom row, optional safety stops, and a no-decompression limit dive planner. The simplified settings allow for three breathing gas mixtures (Air or Nitrox) and place a greater emphasis on the maximum operating depth (MOD) and no decompression time limit (NDL). The display prominently warns the diver if their depth is near, at, or exceeds the MOD of the selected breathing gas. Optional safety stops are user configurable to be 3, 4, 5 mins, or adaptable. When using the Adapt setting, a 3-minute safety stop will be used, unless the dive exceeds { 100ft | 30m } or the NDL falls below 5 minutes, in which case a 5-minute safety stop is used. If the diver exceeds the NDL and requires stops, the display turns red and warns “DECO STOP” with the mandatory depth and stop times.
