The Teric from Shearwater Research of Canada is a fully technical dive computer with recreational divers in mind. The Teric includes open-circuit and closed-circuit Air, Nitrox, and Trimix multi-gas functionality and 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 single-press access to 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 nearby divers.
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 can wirelessly connect up to four optional transmitters*, allowing the diver to monitor up to four tank pressures. It can also calculate 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.
