Garmin Descent G2 Dive Computer & GPS Smartwatch

Why Divers Choose the Garmin Descent G2

The Garmin Descent G2 is designed to grow with you as your diving progresses. Its vivid 1.2-inch AMOLED display makes critical dive information easy to read underwater, while a sapphire crystal lens, leakproof inductive buttons, and a 100-meter dive rating provide the durability needed for regular dive use.

Seven dedicated dive modes cover recreational scuba, advanced multi-gas diving, closed-circuit rebreathers, gauge diving, and multiple freediving disciplines. Garmin's Bühlmann ZHL-16C decompression model supports adjustable conservatism and custom gradient factors, while Nitrox and Trimix support allows divers to configure up to 12 breathing gases.

Garmin's NDL Aware™ depth metrics help show how changes in depth can affect your remaining no-decompression time, while Dive Readiness uses factors such as sleep, stress, recent exercise, and previous dives to provide additional insight when planning your next dive. Surface GPS records dive entry and exit locations, and a built-in 3-axis compass handles underwater navigation.

When the dive day is over, the Descent G2 continues working as an everyday multisport smartwatch with heart-rate monitoring, advanced sleep tracking, training tools, more than 100 activity profiles, smart notifications, Garmin Pay™, and automatic dive-log syncing through the Garmin Dive™ app.
