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.
NEW Features of Descent G2 vs. Descent G1
NEW! TOUCHSCREEN AMOLED DISPLAY
Rugged, watch-style dive computer with a bright 1.2″ touchscreen AMOLED display to make critical information easy to read at any depth,
with a sapphire lens and leakproof buttons.
NEW! VELOCITY CHART
Freedivers can now log and analyze their apnea dives in greater detail. Descent G2 will log velocity so you can review your descent and ascent rates, along with hang time, throughout your apnea activity.
NEW! DIVE READINESS
Get insights into how physically prepared you are for your next dive based on your sleep, stress, recent exercise and dives.
NEW! POOL APNEA MODE
The new pool apnea mode allows freedivers to track their pool training sessions by offering preset and custom interval training for static and dynamic apnea dives, as well as custom start depth for automatic tracking of dives. Plus, it features a breathe-up timer with competition-style countdown and alerts.
NEW! GARMIN MESSENGER™ APP
Communicate via two-way text messaging4 above the water on your wrist.
EXPANDED! DIVE MODES
Track multiple dive modes, including recreational, advanced, technical, freediving and pool apnea. Also get customizable dive modes by adding additional screens for each dive mode that features the fields you want to see.
