Garmin Descent Mk2i Dive Computer: ScubaLab Testers Choice

We tested the Garmin Descent Mk2i dive computer.

Refined, highly-capable, yet remarkably easy to use, it was our Testers Choice for dive computers.

We tested it at the University of Southern California Hyperbaric Chamber on Catalina Island. We also tested it in the field at Blue Grotto Dive Resort in Central Florida. We put it through a series of simulated dives alongside other computers to gauge the performance of its decompression algorithm. We evaluated how easy it was to set up and use, how well we could see the screen in different conditions, and how well it presented important data during our dive.

The air-integrated Mk2i was so new when we received our test sample that its full manual wasn’t yet available. Fortunately, it’s so easy to set, navigate and operate that we didn’t have an issue using it. In fact, no computer-scored higher for easy and intuitive operation—which is saying something because the Mk2i is packed with features including a heart rate monitor, GPS, mapping and a long list of fitness and adventure activities. “Lots to explore here,” one tester noted. The 1.4-wide color display is crisp, well-organized, and highly visible in all conditions, and test divers rated it excellent for readability underwater. Alternate dive screens offer extensive data, and you can scroll through them by button or with a double-tap of the screen. Graphics are clear and easy to understand, and critical data are accompanied with both audible and vibrating alerts. The Mk2i can view the tank pressure and battery status of up to four other divers, and can be paired with Garmin’s diveable inReach Mini satellite communicator to receive text alerts and send an SOS on the surface. Despite the other goodies, the Mk2i is a dive computer first and foremost, and an excellent one at that. The Garmin Descent Mk2i is our Testers Choice for dive computers.
