Garmin Descent Mk3i: discover a deeper connection

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.

Discover a deeper connection with the Descent Mk3i smartwatch feature dive computer. Made specifically for divers, the series combines a bright 1.2" or 1.4" AMOLED display with scratch-resistant sapphire lenses, a dive-resistant case up to 200 meters and waterproof inductive buttons. All models are equipped with multiple scuba diving modes, both recreational and technical, and freediving; they come with a brand new dive preparation tool, developed by Garmin, which shows how everyday factors such as sleep, exercise, stress and jet lag can influence the overall health of the body: this way you can make decisions more aware when planning your dives. The Mk3i version features SubWave™ sonar technology for diver-to-diver communication via pre-set messages (coming soon via software update), also supports tank pressure, depth and distance monitoring (the latter coming soon via software update) for up to eight divers, when paired with the Descent T2 transceiver (purchased separately). An integrated LED flashlight (51mm versions only) lets you fin in low-light conditions, above or under water. DiveView™ maps offer depth contours and over 4,000 dive sites to help you discover the best places to dive and orient yourself.
