Garmin Descent™ Mk3i – 51mm Carbon Grey DLC Titanium + Descent T2 Transceiver

The Descent Mk3 series comes in two sizes – 43mm and 51mm (so effectively the same rough sizes as the Descent MK2/MK2i and the MK2S) – with air integration options on both, and features a bright touchscreen AMOLED display, a 200m dive-rated case with metal leakproof buttons that are fully operational at that depth, and up to 48 hours of battery life in dive mode.

The 51mm Descent Mk3i also comes with a built-in LED flashlight for greater visibility in low-light conditions – even underwater.

When paired with the Descent T2 transceiver, divers will be able to send out assistance alerts to other connected divers, and exchange preset messages with other divers up to 30 metres away on a soon-to-be-released software update.

Designed by divers for divers, the Descent Mk3 series is ready for the next excursion with dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather.

 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.

*Air Integration - Pair with our Descent^™ T2 transceivers (sold separately) for integrated pressure monitoring on up to 8 tanks via the SubWave sonar data network.

*Subwave Sonar Networking - Exchange preset diver-to-diver messages (coming soon) up to 30 meters as well as monitor tank pressures and depth for up to 8 divers within a range of 10 metres¹.

*Dive Readiness Tool - This Garmin first technology shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body — to help gauge when you are best prepared to dive.

*Dive Modes - Get multiple dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather.

*Diveview Maps - Colour maps on your wrist offer bathymetric depth contours and more than 4,000 dive sites to help you discover new places to dive and get oriented.

*Dive Focused Design - With its bright 1.4″ AMOLED color display, sapphire lens, 200-meter dive-rated case and leakproof metal inductive buttons, this watch is built to go deep.

• Diver Assistance (coming soon): If a diver is in need of help, this revolutionary tool will let them request assistance right from their watch thanks to enhanced SubWave sonar technology. When using a Descent Mk3i dive computer and Descent T2 transceiver, divers will be able to send out an assistance alert to other connected divers. Nearby connected divers will then be able to see the diver’s depth and distance and monitor them until assistance is no longer required.
• Diver-to-diver messaging (coming soon): Using SubWave technology,divers with a Descent Mk3i and Descent T2 transceiver will be able to exchange preset messages with other connected divers, up to 30 meters away³.
• Dive group tracking: Using air integration, keep track of where other divers are in the group. See depth and tank pressure of up to eight divers who are using a Descent T2 transceiver, up to 10 meters away.
• Dive-focused design: A 200-meter dive-rated case with a strong, scratch resistant sapphire lens operates at twice the depth of the previous generations and features metal buttons that are leakproof and fully functional at 200 meters. Plus, a bright touchscreen AMOLED display provides greater visibility—even underwater.
• Built-in LED flashlight: Available on the 51mm Descent Mk3i, an integrated LED flashlight with built-in strobe mode gives divers greater visibility in low-light conditions, above or below the water.
• Dive readiness: See how lifestyle factors like sleep, exercise, stress and jet lag can affect the body’s overall preparedness to dive. A higher readiness score may suggest it’s time to dive in while a lower score may be reason to consider using a higher conservatism setting or choose an easier dive.
