Garmin Descent G2

Descent G2 is the watch-style dive computer for both your worlds. It features a bright AMOLED display and 10 ATM dive rating — and it tracks multiple dive types whether you’re a recreational scuba diver, technical scuba diver or freediver. Descent G2 is enabled with GPS to help mark your surface entry and exit points, and it includes the dive readiness feature so you know how physically prepared you are for your next dive.

Pair with the Garmin Dive™ smartphone app to upload, share and review dives, and store your favorite dive site locations. The Descent G2 dive computer is made with recycled ocean-bound plastics and includes built-in sports apps and 24/7 health monitoring. Plus, you’ll get smart notifications (when paired with your compatible smartphone) and up to 10 days of battery life in smartwatch mode.

NEW Features as of November, 2025

NEW! NDL AWARE™ DEPTH METRICS

Extend your bottom time with NDL Aware depth metrics that work in real time to show how specific depth changes can impact your no-decompression limit.

NEW! BREATHING VARIATIONS

For a closer glimpse of your health, this feature helps you understand shifts in your breathing patterns as you sleep⁵. These shifts could
be related to environment, alcohol or potential sleep disorders such as sleep apnea.

NEW! POSTDIVE ACTIVITY GUIDANCE

Physical fitness is important for divers, but exercising shortly after a dive can increase the risk of decompression sickness. Postdive activity
guidance alerts you when it may be a good idea to postpone your training due to a recent dive.
