Garmin Descent T2 Tank Pod Transceiver

Get tank pressure and battery remaining sent to paired compatible Descent dive computers that will then also compute gas time remaining and gas consumption rate. Monitor up to eight (8) transceivers via SubWave™ sonar technology so you can dive with multiple tanks or monitor transceivers of other divers in your group when they are within {33 feet | 10 meters}. The T2 can be mounted directly on to the standard HP port of a SCUBA first stage or with the addition of the included swivel adapter (aka "air spool") it can be installed on the end of a high-pressure SCUBA hose. Often called "air integration", the T2 tank pod is currently only supported by the Garmin air integrated model dive computers. The T2 tank pod is NOT supported by the Mk1, Mk2 (without the 'i'), Mk2s, Mk3 (without the 'i'), G1 or X30 models; nor is it compatible with any other brand of dive computer.

• Tank pressure transmission range (surface via ANT, underwater via SubWave): Up to {33 feet | 10 meters}
• Dive messaging range up to {98 ft | 30 m} requires Descent Mk3i or X50i dive computer
• Depth rating: {660 fsw | 200 msw}
• Gas Pressure rating: {4351 psi | 300 bar}
• Physical Dimensions: {3.33 x 1.44 x 1.44 in | 84.50 x 36.52 x 36.52 mm }
• Battery: Up to 100 hours, using user changeable and widely available 3V CR123A lithium
• Thread type: 7/16-inch UNF (standard HP fitting used in SCUBA)
• Surface operating temperature: From -20 to 60°C (from -4 to 140°F)
• Underwater operating temperature: From 0 to 40°C (from 32 to 104°F)
• Tank pressure is ±5% full scale accuracy

What's in the box: Garmin Descent T2 tank pod (aka tank pressure transceiver) with installed CR123A battery, flow restrictor, swivel adapter (aka 'air spool') for use with HP hoses, and quick start user guide.

The Descent T2 should always be installed using either a flow restrictor or an air spool, both included with this kit. Which one is used depends on the method of installation. The flow restrictor should be installed on a Descent T2 when it is attached directly to the high pressure port on a first stage regulator. When the T2 is attached to a high pressure hose, the air spool should be used. Using the transmitter without either the flow restrictor or air spool could result in serious injury or death from an air pressurization failure. Refer to the Descent T2 Manual for more details.

In rare cases, the body of some first stage regulator designs will have hose ports oriented such there is not room to accept a wireless tank pressure transmitter without interfering with hose routing. The solution is to use a standoff adapter, or some divers prefer to use a short HP hose in place of the standoff. All high pressure hoses use an 'air spool' with two tiny o-rings to mate the swivel connector on the hose to the fitting, and the T2 package includes a special air spool for use with standard HP hoses. The design of the T2 tank pod is such that it's use with a standard HP hose requires the special air spool included with the transceiver package.

The T2 communicates underwater using an audible sonar signal, meaning the T2 emits a half second "chirp" every 4 seconds. Garmin says the sound is normal, and the volume can be lowered by reducing the power setting of the T2 and in some cases by repositioning the T2. Most divers (especially those that wear a hood) don't notice the sound or find it indistinguishable from background noise, but some divers do report finding the sound of the T2 to be annoying.
