Track every breath, every tank, and every buddy on your dive right from your wrist by pairing the Descent T2 transceiver with compatible air-integrated Descent dive computers (sold separately). Enhanced SubWave sonar technology enables monitoring of up to 8 tanks (air pressure, use rate, time remaining, and more) and exchanging preformatted diver-to-diver messages with networked buddies wearing compatible air-integrated dive computers (requires software v.15.70 or later). With a 20 ATM dive rating, the transceiver ensures confidence at greater depths. A streamlined BLUETOOTH Low Energy pairing process simplifies identifying buddies by name via their Descent T2 transceivers. 
Compact dive accessory attaches to high-pressure regulator ports without hose interference. Built to endure harsh conditions, the Descent T2 transceiver is dive-rated to 20 ATM (Garmin.com/waterrating), allowing deeper dives with confidence. It sends tank pressure, air time remaining, and air consumption rate directly to compatible air-integrated Descent dive computers (sold separately) for better situational awareness. For improved communication, exchange preformatted diver-to-diver messages with other Descent T2 transceiver users wearing SubWave-compatible dive computers up to 30 meters away (requires software v.15.70 or later). Pair up to 8 transceivers with a compatible Descent dive computer within range to monitor multiple tanks or track buddies’ air levels and depths up to 10 meters. Simplified Bluetooth Low Energy pairing helps identify buddies by name. The Descent T2 transceiver offers up to 100 hours of dive time with a user-replaceable CR123A lithium battery.
