The Garmin Descent™ T2 Transceiver is an advanced wireless tank monitoring system designed for technical, recreational, and group divers. When paired with a Descent Mk3i dive computer, it provides real-time tank pressure, air time remaining, air consumption rate, and battery status. Using SubWave™ sonar technology, divers can track up to 8 tanks at once—perfect for buddy diving and dive instructors.
Built for deep dives, the Descent T2 features a rugged 20 ATM (200m) depth rating and operates in extreme temperatures. Its simplified wireless pairing makes tank identification easy, and an upcoming update will enable preformatted diver-to-diver messaging within 30 meters of range.
Every breath, every tank, every buddy on your dive — track them all on your wrist when you pair the Descent T2 transceiver with your compatible air-integrated Descent™ dive computer1.
Enhanced SubWave™ sonar technology lets you monitor up to 8 tanks when under water — viewing air pressure, depth, use rate and time remaining — for multiple types of diving. Plus, you can even communicate via preformatted messages (coming soon) with other networked buddies wearing their Descent™ Mk3i dive computers.
DEEP DIVE-RATED
Built to withstand the elements, the Descent T2 transceiver is dive-rated to 20 ATM (200 meters) — so you can dive deeper without worry.
KNOW YOUR TANK
Get tank pressure, air time remaining, air consumption rate and battery remaining — all sent directly to your paired air-integrated Descent dive computer1.
LINK MULTIPLE DIVERS
See your dive buddies' tank pressures and depths at a glance. Pair up to 8 transceivers on your group’s tanks with each compatible air-integrated dive computer1 within a range of up to 10 meters.
DIVER MESSAGING
Exchange preformatted diver-to-diver messages (coming soon) with other Descent T2 transceiver-networked buddies wearing Descent Mk3i dive computers up to 30 meters away.
EASY TANK ID
A simplified pairing process using wireless area networking makes it easy to identify your buddies’ names with the Descent T2 tank transceivers they’re wearing.
