The Dive360 Take

The Descent T2 is the direction we would look for Garmin divers who want cylinder-pressure information on their wrist. Paired with a compatible air-integrated Descent computer, it brings pressure, gas-consumption and remaining-air information into the same view as your dive data.

With a compatible Mk3i setup, the SubWave network also supports buddy monitoring and preset diver messages. That is useful for a team using matching equipment, although the available functions depend on the computers, software and underwater conditions. This listing is for the T2 transceiver; the watch is separate.

Our team’s experience

Molly’s pick

My regular kit

Pairing the transceiver with my watch is really easy. Having it paired is also really convenient for a quick glance instead of trying to bend and find my SPG, because I always know where my wrist is. I also like how I can get more insight into my breathing data, and all my data is saved for later and for logging.
The serious stuff
  • Garmin part number 010-13308-00; compatible air-integrated Descent computer required and sold separately.
  • SubWave sonar sends pressure and depth data over a range of up to 10 m; supported diver messaging has a range of up to 30 m. Actual communication depends on conditions and line of sight.
  • Supports monitoring of up to eight tanks with compatible devices; available network features depend on the computer and current software.
  • Cylinder pressure, gas-use rate, remaining-air time and battery status are available on a supported paired computer.
  • User-replaceable 3 V CR123A lithium battery; up to 100 hours of use.
  • Standard 7/16-20 UNF high-pressure port connection.
  • Rated cylinder pressure: 300 bar. Dive rating: 20 ATM, equivalent to 200 m.
  • Not for gas mixtures containing more than 40% oxygen.
  • Messaging is a supplementary function and must not be relied on for emergency assistance.
Why we like it

Tank information on the same wrist display makes routine checks convenient. With supported devices, buddy data adds another useful view of the dive team.

The replaceable battery suits regular use and travel. It is a practical addition when you already like the Garmin ecosystem and want your dive equipment to work together.

Who we recommend it to

Divers with a compatible air-integrated Garmin Descent computer who want wireless cylinder-pressure monitoring. Also useful for buddy teams using supported Garmin equipment and wanting access to SubWave monitoring and messaging.
