The Garmin Descent MK3i 51mm Ti/Ti Dive Computer is the ultimate dive watch for those who want to discover a deeper connection with the underwater world. Featuring SubWave™ sonar-based communication and diver monitoring, this advanced, air-integrated¹ dive computer and smartwatch comes with Garmin innovations to help prepare you to make the most of your diving experience — plus multisport training and smart features for your active life out of the water.

With up to 66 hours of battery life in dive mode, you can explore the depths for longer periods of time. Choose from multiple dive modes, including nitrox and trimix, gauge, apnea, apnea hunt and closed-circuit rebreather, to suit your diving needs. The DiveView™ colour maps with depth contours and dive sites help you discover new places to dive and get oriented.

The Dive Readiness Tool is a Garmin first technology that shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body — to help gauge when you are best prepared to dive. The built-in LED flashlight works above or below water, making it easy to see in low-light conditions.

Air integration is made possible by pairing with our Descent™ T2 transceivers (sold separately) for integrated pressure monitoring on up to 8 tanks via the SubWave sonar data network. SubWave sonar-based diver messaging (coming soon) allows you to exchange preset diver-to-diver messages up to 30 meters as well as monitor tank pressures and depth for up to 8 divers within a range of 10 metres1.

The dive-focused design of the Garmin Descent MK3i 51mm Ti/Ti Dive Computer is evident in its bright 1.4″ AMOLED color display, sapphire lens, 200-meter dive-rated case and leakproof metal inductive buttons. Whether you're a seasoned diver or just starting out, this dive watch is the perfect companion for your underwater adventures.
