Garmin Descent T1 Diving Transmitter lets you know your tank pressure from a simple glance to your wrist. Pair the T1 transmitter with your Garmin Descent Mk2i dive computer. Monitor up to 5 tanks via SubWave sonar technology so you can dive with multiple tanks or see your mate's air levels! Descent T1 enables you to monitor tank pressure, remaining air time and air consumption rate for multiple types of diving.

The Descent T1 Transmitter is built to withstand the elements and is water-rated to 11 ATM. It also allows you to view your tank pressure, remaining air time, air consumption rate and battery remaining which will be sent directly to a paired compatible descent dive computer. You can pair up to 5 transmitters to each compatible dive computer within a range of 10 metres.
