## Description

Featuring SubWave sonar-based communication and diver monitoring, this advanced, air-integrated1 dive computer and smartwatch comes with Garmin innovations to help prepare you to make the most of your diving experience — plus multisport training and smart features for your active life out of the water.

## Features

- Every breath, every tank, every buddy on your dive — track them all on your wrist when you pair the Descent T2 transceiver with your compatible air-integrated Descent dive computer.
- Enhanced SubWave sonar technology lets you monitor up to 8 tanks when under water — viewing air pressure, depth, use rate and time remaining — for multiple types of diving. Plus, you can even communicate via preformatted messages (coming soon) with other networked buddies wearing their Descent Mk3i dive computers.
- Built to withstand the elements, the Descent T2 transceiver is dive-rated to 20 ATM (200 meters) — so you can dive deeper without worry.
- Get tank pressure, air time remaining, air consumption rate and battery remaining — all sent directly to your paired air-integrated Descent dive computer.
- See your dive buddies' tank pressures and depths at a glance. Pair up to 8 transceivers on your group’s tanks with each compatible air-integrated dive computer within a range of up to 10 meters.
- Pair with our Descent T2 transceivers (comes with it) for integrated pressure monitoring on up to 8 tanks via the SubWave sonar data network.
- Exchange preset diver-to-diver messages up to 30 meters as well as monitor tank pressures and depth for up to 8 divers within a range of 10 meters1.
- Get multiple dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather.
- Exchange preformatted diver-to-diver messages with other Descent T2 transceiver-networked buddies wearing Descent Mk3i dive computers up to 30 meters away.
- A simplified pairing process using wireless area networking makes it easy to identify your buddies’ names with the Descent T2 tank transceivers they’re wearing.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best dive computer and watch I've ever used
*by S***E on December 7, 2024*

I know these are not cheap but I have to say after 6 months of use daily I have never had a better dive computer/watch

### ⭐⭐⭐⭐⭐ Best watch ever!!!!
*by L***R on October 30, 2024*

I can't be more happy and amazed by this watch. Absolutely the greatest. I want to own every color. Buy this watch you will not regret it!

### ⭐⭐⭐ Great hardware but you don't own your data or divelogs
*by F***T on September 5, 2025*

Hardware and UI are excellent — great watch, clear dive display.But your dive data is locked behind Garmin Connect, with no way to access logs offline or via BLE. As a diver, I should own my own logs. Until they open access, this keeps Garmin from being a 5-star dive computer.This makes the product dangerous to use with other dive computers as it will never be able to sync data between them or be unified with other computers.Especially in offline settings but with devices, this makes Garmin products significantly less useful. Stay away if you want to own your data or are worried about offline log sharing or dive watch data syncing access.Additionally Garmin cloud access is gated by approved vendors so normal developers or users will never get access to the fit dive logs.Garmin diving api was hinted at being available in late 2026...but that's uncertain. I recommend going shearwater if you want a dive computer and only keeping a single Garmin for payment and other connectivity features of a diving smart watch. Or you could buy an apple watch... And not use it for diving.
