Garmin Descent T2 Transceiver

Description

Advanced Air Integration for the Garmin Descent Ecosystem

The Garmin Descent T2 Transceiver brings real-time tank pressure and dive network data directly to compatible Garmin Descent dive computers.

Using Garmin’s SubWave sonar technology, the T2 transmits pressure and depth information underwater while also supporting compatible diver-to-diver communication features.

For recreational divers, it provides convenient wireless air integration. For technical divers, instructors, and dive teams, the T2 offers a flexible platform for monitoring multiple cylinders and paired divers.

Monitor Your Tank Pressure at a Glance

Once paired with a compatible Garmin Descent dive computer, the T2 can transmit cylinder pressure directly to the diver’s wrist.

This allows compatible Descent computers to display information such as:

• Current tank pressure
• Estimated gas remaining
• Gas consumption data
• Depth information
• Dive network status

The T2 uses a standard high-pressure regulator port connection and is rated for cylinder pressures up to 300 bar / 4,351 psi.

Pair Multiple Transceivers

Compatible Garmin Descent computers can pair with up to eight Descent T2 transceivers.

That makes the T2 useful for configurations including:

• Single-cylinder diving
• Doubles
• Stage bottles
• Decompression cylinders
• Multi-gas technical diving
• Instructor or team monitoring

Each transceiver has a unique identification number, allowing compatible computers to distinguish between multiple units.

SubWave Sonar Network

The Descent T2 uses Garmin’s SubWave sonar network for underwater communication.

Pressure and depth information can be transmitted at distances of up to approximately 33 feet / 10 meters underwater.

With compatible Garmin Descent devices, diver messaging can operate at distances of up to approximately 98 feet / 30 meters.

This technology enables features such as:

• Tank pressure monitoring
• Diver depth monitoring
• Dive group tracking
• Preset diver-to-diver messaging
• Diver assistance features

Available functions depend on the paired Garmin Descent model.

Built for Serious Diving

The T2 is rated to withstand pressure equivalent to a depth of 200 meters.

Its rugged construction and compact form factor allow it to mount directly to a regulator first-stage high-pressure port without adding unnecessary bulk.

Long Battery Life

The Descent T2 uses a readily available CR123A lithium battery and provides up to approximately 100 hours of battery life under Garmin’s testing conditions.

The user-replaceable battery design makes it easy to keep a spare on hand for dive trips and technical diving operations.
