The Garmin Descent™ T2 Transceiver brings real-time tank pressure monitoring and advanced underwater communication to compatible Garmin Descent dive computers. Designed for recreational, technical, and professional divers, the T2 delivers reliable air integration using Garmin's proprietary SubWave™ sonar technology.
By pairing the T2 with a compatible Garmin air-integrated dive computer, you'll receive live tank pressure, air consumption rate, remaining air time, and battery status directly on your wrist—helping you stay focused on the dive while improving awareness and safety.
Why We Like the Garmin Descent™ T2
Real-Time Air Integration
Monitor tank pressure, estimated air time remaining, gas consumption rate, and transceiver battery status directly from your compatible Garmin Descent dive computer.
SubWave™ Sonar Technology
Garmin's underwater SubWave™ communication provides reliable transmission of tank data without traditional radio-frequency limitations underwater.
Monitor Multiple Divers
Pair and monitor up to 8 transceivers simultaneously, making it ideal for instructors, divemasters, technical divers, and group dives. View nearby divers' tank pressures and depths directly from your compatible dive computer.
Diver-to-Diver Messaging
When paired with compatible Garmin Descent dive computers, the T2 enables preformatted underwater messaging, allowing connected divers to exchange preset messages during the dive for improved communication and situational awareness.
Easy Wireless Pairing
A simplified pairing process makes it easy to assign transceivers to individual tanks and identify dive buddies throughout your dive network.
Built for the Underwater Environment
Rated to 200 meters (20 ATM) and engineered to withstand demanding dive conditions, the T2 is built for years of reliable performance.
Compatibility
The Garmin Descent™ T2 is compatible with select air-integrated Garmin Descent dive computers, including:
- Garmin Descent™ X50i
