Garmin Descent T2 Transceiver with Subwave Wireless Communication

Items Description

The Garmin Descent T2 is a wireless tank transmitter designed for divers who use a compatible air-integrated Descent dive computer. It pairs via SubWave sonar to relay scuba cylinder pressure, depth, gas consumption rate, and remaining dive time directly to a wrist display, reducing the need to check a submersible pressure gauge.

 

Built for both recreational and technical divers, the Descent T2 brings clear digital data to each dive. On the surface it uses ANT technology to sync with a compatible watch, while underwater the SubWave sonar network takes over, transmitting data through water without a physical hose. With a battery life of up to 100 hours per charge, this transceiver supports multi-day dive trips and extended dive planning.

 

Key Advantages of the Garmin Descent T2 Transceiver with Subwave Wireless Communication

 

1. SubWave Sonar Data Transmission

The Descent T2 uses SubWave, a sonar-based wireless network developed for underwater communication. This allows the transceiver to send tank pressure and diver depth data to a paired Garmin Descent dive computer, supporting a clean, hose-free configuration.

 

• Wireless Range: Effective underwater transmission range of approximately 3 metres, with surface range up to 10 metres.
• Frequency: Operates at 2.4 GHz with a maximum output of 5.22 dBm.
• Hose-Free Design: Removes the need for a traditional high-pressure hose, offering a more streamlined equipment setup.

 

2. Multi-Tank Monitoring for Technical Dives

When paired with a compatible air-integrated Descent dive computer, the T2 allows monitoring of up to eight tanks during a single dive. This makes it a strong fit for technical divers managing multiple cylinders.

 

• Up to 8 Tanks: View pressure, depth, and remaining time for each paired tank.
• Gas Consumption Rate: Track usage to adjust breathing and plan gas reserves.
• Compatible Descent Computers: Works with Descent Mk2i, Descent Mk3i, and other air-integrated Garmin dive models (verify compatibility with Garmin's support resources).

 

3. Durable Build for Demanding Environments

The transceiver is constructed for regular exposure to saltwater, pressure, and handling during dive operations. Its sealed housing is designed to withstand the physical demands of diving while maintaining reliable wireless output.

 

• Water Resistance: Rated for depths up to 100 metres, suited for recreational and technical diving profiles.
• Secure Mounting: Compatible with standard scuba cylinder valves and first-stage regulators.
• Compact Form Factor: Low-profile design minimises drag and accidental contact during dives.

 

4. Long Battery Life for Extended Diving

Regular divers and those on liveaboard trips benefit from the T2's rechargeable battery, which delivers up to 100 hours of operation per full charge. This reduces the frequency of charging sessions during multi-day dive rotations.

 

• Rechargeable Battery: USB-charged, with a single charge lasting up to 100 hours in typical use.
• Battery Status Alerts: The paired dive computer displays current transceiver charge level.
• Low-Power Idle: Minimal power draw when not actively transmitting.

 

5. Surface Connectivity via ANT Technology

When the transceiver is above water, it uses ANT to pair and sync with a compatible Descent watch. This enables straightforward setup, firmware updates, and pre-dive checks without additional cables or desktop software.

 

• Easy Pairing: Quick pairing with a desired dive computer before entering the water.
• Firmware Updates: Receive newest software through the paired watch or Garmin application.
• Works with Garmin Ecosystem: Integrates with the wider Garmin dive and fitness product range.

 

The Garmin Descent T2 Transceiver with Subwave Wireless Communication is designed for divers who already use a compatible Garmin air-integrated dive computer and want to move away from traditional pressure hoses. It is particularly well-suited to technical divers managing multiple tanks, as well as liveaboard divers who value long battery life and reliable underwater data transmission. For recreational divers interested in a cleaner, more information-rich dive setup, the Descent T2 offers a practical upgrade to an existing Garmin dive system.
