ADD DIVER COMMUNICATION TO TANK PRESSURE MONITORING

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.

Dive with added confidence and situational awareness.

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.
