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 with other networked buddies wearing their Descent™ Mk3i dive computers.
Dive with added
confidence and
situational
awareness.
