The Garmin Descent MK3I is a watch-style dive computer with GPS and a sunlight-readable 1.4" 454x454 AMOLED display, so you can read your dive data at a glance. DiveView color maps show bathymetric depth contours and more than 4,000 dive sites, and multi-band GPS handles navigation at the surface. Dive modes cover single-gas dives, nitrox, trimix, gauge, apnea, apnea hunt and closed-circuit rebreather, so one watch fits several kinds of diving. Add the optional Descent T2 transceiver (sold separately) and you get air integration with pressure monitoring on up to 8 tanks.

A built-in LED flashlight offers variable intensities and strobe modes, which gives you more visibility above and below the water. The fiber-reinforced case has a stainless steel bezel and a dive rating of 200 meters, and this version is finished in Carbon Gray DLC Titanium with a black silicone band. Battery life is rated at up to 30 hours in dive mode, longer than the earlier models in the series. The watch has 32 GB of built-in storage for music files and works with Android and Apple iOS phones for smart notifications.
