Descent™ T2 Transceiver


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.
