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 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.
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.
