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 computer. 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 computer.
• 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.
