The Garmin Descent T1 Transmitter will track tank pressure when paired with the Descent Mk2i computer, up to 5 cylinders, via the innovative SubWave sonar technology. Thus, you can check all your tanks or your buddies' air levels via your own computer.

Monitor much more than tank pressure: remaining air time, air consumption rate for multiple types of diving and remaining battery for up to 5 transmitters to each computer within a range of up to 10 meters.

Rated to withstand great pressure, the Descent T1 can dive down to 110 metres. This Garmin innovation won't disappoint you when combined with the Mk2i computer!
