Product Information

This package pairs the Garmin Descent Mk3i dive computer with the Garmin Descent T2 transceiver, giving you an air-integrated smartwatch and a compatible tank-pressure transceiver in one order. The Mk3i is available in four titanium color and band combinations, Bronze PVD Titanium with a French Gray Silicone Band, Carbon Gray DLC Titanium with a Black Silicone Band, Carbon Gray DLC Titanium with a DLC Titanium Band, or Silver and Black PVD Titanium with a Black/Pebble Gray Silicone Band, and in a 43mm or 51mm case size, so pick the fit and finish you want before checkout.

Underwater, the Mk3i's SubWave sonar system lets you send preset messages to dive buddies up to 30 meters away and keep tabs on tank pressure and depth for up to 8 divers within a 10-meter range. Pair it with the included Descent T2 transceiver and you get live tank pressure, depth, air consumption rate, and remaining air time sent straight to your wrist, with air integration on the Mk3i supporting up to 8 tanks total if you add more transceivers later. Above the surface, the Mk3i still functions as a full smartwatch, with an AMOLED touchscreen display, multi-band GPS, Garmin Pay, Pulse Ox blood oxygen tracking, sleep score and insights, and up to 25 days of battery life in smartwatch mode (10 days in always-on mode).

The Descent T2 transceiver itself is dive-rated to 20 ATM (200 meters), matching the Mk3i's own 200-meter Dive water rating, and runs on a 3V CR123A lithium battery good for up to 100 hours of operation. Each T2 arrives with an air spool and full documentation so you can get it threaded onto your tank valve and paired with your Mk3i without hunting down extra parts.

Frequently Asked Questions

How does the Garmin Descent T2 transceiver work with the Descent Mk3i dive computer?

The T2 pairs with the compatible air-integrated Descent Mk3i using Garmin's SubWave sonar system. Once paired, it sends live tank pressure, depth, air consumption rate, and remaining air time straight to your wrist. You can connect up to 8 transceivers to one dive computer within a 10-meter range, so a dive team can keep an eye on everyone's air and depth at a glance.

What band or strap sizes fit the Garmin Descent Mk3i?

The Descent Mk3i uses Garmin's QuickFit bands in 26mm, so straps snap on and off without tools. It comes with either a silicone strap or a DLC-coated titanium strap. We don't have a separate wrist-size or fit chart in our records, so check the product page for sizing guidance.

What dive modes and features does the Garmin Descent Mk3i support?

It covers nitrox, trimix, gauge, apnea, apnea hunt, and closed-circuit rebreather (CCR) dive modes. The case is fiber-reinforced polymer with a titanium rear cover, a sapphire lens, and a DLC-coated titanium bezel, and it's rated for diving to 200 meters. On the smartwatch side it also has an AMOLED touchscreen, built-in mapping, and multi-band GPS.

Is the Garmin Descent Mk3i just a dive computer, or does it work as a smartwatch too?

It's built to do both. Beyond dive tracking, it includes sleep score and insights, training readiness and training status, daily suggested workouts, Pulse Ox blood oxygen, Garmin Pay, and onboard music storage. Our records show two different battery-life figures depending on the version, so check the product page for the exact number on the model you're buying.

What exactly comes in this bundle?

The bundle includes one Garmin Descent Mk3i dive computer and one Garmin Descent T2 transceiver for tank pressure monitoring. The T2 itself ships with an air spool and its documentation included.

How fast will this ship and what's the return policy?

Orders over our free-shipping threshold ship free with next-day delivery, and the product page shows the honest, current delivery estimate for your order. If it's not a fit, it's covered by our standard DiveCatalog returns policy.
