Garmin Descent T2 Transceiver

T2 transceiver uses sonar technology to communicate with paired, compatible air-integrated Descent dive computers from up to 10 meters away. It allows divers to monitor tank pressure, depth, gas consumption rate and gas time remaining for up to eight tanks. Even better, it also allows for two-way communication between networked dive buddies wearing the Descent Mk3i dive computer using preformatted messages.
