Garmin Descent Mk3i Watch Style-Dive Computer (51mm, Carbon Gray with DLC Titanium Band)

The Garmin Descent Mk3i Dive Computer combines advanced dive technology with multisport smartwatch features. With air integration via the SubWave sonar network (compatible with up to 8 Descent T2 transceivers, sold separately), it tracks tank pressure, depth, and diver data. SubWave also supports diver-to-diver messaging (upcoming software update). Multiple dive modes include single/multi-gas, gauge, apnea, CCR, and more.

Features like the Dive Readiness tool evaluate sleep, stress, and activity to help you dive safely. DiveView color maps show bathymetric contours and 4,000+ dive sites. Built for performance, it includes a 1.4-inch AMOLED display, sapphire lens, 200m dive rating, and leakproof buttons.

Additional tools include an LED flashlight, customizable dive screens, a built-in dive log, an underwater compass, a variometer, tide data, Big Numbers Mode, and GPS surface tracking. Lume mode aids visibility in low light, while compatibility with the Garmin Dive app and inReach devices enables easy syncing and off-grid messaging.

Beyond diving, the Mk3i offers VO2 Max tracking, Surfline Sessions for surfers, ski and snowboard metrics, and apps for trail running, cycling, swimming, golf, and more. Battery life reaches up to 66 hours in dive mode and 25 days in smartwatch mode.
