Descent Mk3i Dive Computer
Immerse yourself in the Descent Mk3i watch-style dive computer for a heightened diving experience. With versatile dive modes, SubWave sonar technology for diver communication, and support for monitoring tank pressures and depth for up to eight divers (with the Descent T2 transceiver), this device offers enhanced functionality. Additionally, a built-in LED flashlight ensures visibility in low-light conditions, both above and below water.

Enhanced Communication
SubWave sonar technology for diver-to-diver messages up to 30 meters, monitoring tank pressures, and depth for up to eight divers within 10 meters (with Descent T2 transceiver).

Advanced Design
Stylish watch-style dive computer with a 1.4" AMOLED display, scratch-resistant sapphire lens, 51 mm titanium bezel, and optional bracelet.

DiveView Maps
Maps with bathymetric depth contours and details on over 4,000 dive sites for easy location selection and orientation.

Dive Readiness Tool
Garmin-developed tool analyzes lifestyle factors (sleep, exercise, stress, jet lag) impacting body's readiness for diving.

Dive Log Storage
Wrist-based storage for up to 200 dives, with sharing and reviewing capabilities in the Garmin Dive app.

Navigation and GPS
Multi-band GPS for superior positional accuracy, along with ABC sensors, including an underwater compass.

Discover a deeper connection with the Descent Mk3i watch-style dive computer. It features multiple dive modes plus SubWave sonar technology for diver-to-diver communication via preset messages (available with software v.15.70 or later). The device also supports monitoring of tank pressures and depth for up to eight networked divers, when paired with the Descent T2 transceiver (sold separately). Purpose-built specifically for divers, the Descent Mk3i dive computer combines a bright 1.2" AMOLED display with scratch-resistant sapphire lens, 200-meter dive-rated case and metal leakproof inductive buttons. DiveView maps offer bathymetric depth contours and more than 4,000 dive sites to help you find where to dive and get oriented. Plus, a dive readiness tool, developed by Garmin, shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body's overall preparedness for diving - so, ultimately, you can make better-informed dive plan decisions (data presented is intended to be a close estimation of metrics tracked).

This dive computer is designed to help maximize your preparation for the physical and mental challenges of diving. You can also reference ABC sensors with a 3-axis underwater compass as well as surface GPS capabilities to mark your entry and exit points. When you're ashore, built-in sports apps help you stay on top of your fitness, while Garmin Pay contactless payments, music storage and smart notifications keep you connected (compatible smartphone required).


- Garmin Descent T2 Transceiver -
Every breath, every tank, every buddy on your dive - track them all on your wrist when you pair the Descent T2 transceiver with compatible air-integrated Descent dive computers (sold separately). Using enhanced SubWave sonar technology, this system lets you monitor up to 8 tanks (air pressure, use rate, time remaining and more) and exchange preformatted diver-to-diver messages with networked buddies wearing their compatible air-integrated dive computers (available with software v.15.70 or later). The transceiver's 20 ATM dive rating means you can dive deeper with added confidence. A simplified pairing process using BLUETOOTH Low Energy wireless technology makes it easy to identify your buddies' names with the Descent T2 transceivers they're wearing.
