For a comprehensive analysis of your dive parameters, simply pair the Descent™️ T2 transceiver (sold separately) with your Descent Mk3i air-integrated dive computer. This provides you with accurate data on your air consumption and breathing rate and creates a precise overview of your saturation and remaining no-decompression time. In addition, the T2 transmitter allows you to track the data of up to eight dive buddies and monitor their tank pressure and distance (available with software update in 2024) and even allows you to exchange underwater messages with your dive buddies thanks to the Diver2diver function (available with software update in 2024). The topographic DiveView™️ maps offer you orientation at more than 4,000 dive sites worldwide, so you can always find the perfect spot for your next adventure.

The Dive Readiness function of the Descent™ Mk3 gives you completely new insights into your dive readiness and thus enables optimal dive planning. Smart features such as Garmin Pay™ and over 80 sports and outdoor apps accompany you not only underwater, but also in all your activities outside the water.

Dive into the future of diving with the Garmin Descent™ Mk3 - your reliable partner in the depths of the oceans.
