Garmin Descent T2 Dive Transceiver

Stay informed beneath the surface with the Garmin Descent T2, a compact tank-mounted transceiver designed to provide real-time air data and enhanced diver awareness when paired with compatible Garmin Descent dive computers.

Using Garmin's SubWave™ sonar technology, the T2 sends important tank and dive information directly to your wrist, making it easier to monitor your own gas supply and stay aware of other connected divers.

Real-Time Air Integration

Once connected to a compatible Descent dive computer, the T2 continuously transmits essential information from your tank.

Monitor tank pressure, estimated remaining air time, gas consumption and transceiver battery status without needing to rely solely on a traditional pressure gauge.

Stay Connected Underwater

SubWave™ technology extends the capabilities of compatible Garmin diving equipment beyond basic air integration.

With supported Descent devices, divers can monitor selected information from other members of their group. Compatible configurations can also support preset diver-to-diver messaging, providing another way to maintain awareness underwater.

Built for Group Diving

Multiple Descent T2 transceivers can be paired with compatible Garmin dive computers, making the system particularly useful for buddy diving, instructors and organised dive groups.

Connected information can include individual tank pressure and depth data, allowing important dive information to remain accessible from the wrist.

Ready for Serious Depth

The Descent T2 features a rugged, compact construction designed specifically for tank-mounted underwater use.

With a 20 ATM rating and dive capability to 200 metres, it is built to accompany recreational and advanced diving activities in demanding environments.

Simple Tank-Mounted Setup

The compact design integrates directly with compatible diving equipment without adding unnecessary complexity.

Wireless pairing makes it straightforward to identify and assign individual transceivers when using multiple tanks or diving as part of a group.
