Garmin Descent Mk3i 51 mm

For divers who want a larger watch display. The 1.4-inch AMOLED screen and integrated flashlight are the practical differences to try in person. A useful choice when you want a dive watch that also handles everyday activities.

Consider before choosing

Check comfort over your suit and on your bare wrist. A T2 transceiver is an additional component unless your selected bundle includes it.

Garmin Descent Mk3i 43 mm

For a smaller watch footprint. The 1.2-inch AMOLED display brings the Mk3i platform to a more compact case. Compare its screen readability with the 51 mm before deciding.

Consider before choosing

This size does not have the 51 mm model’s built-in flashlight. Confirm the finish, strap and transmitter bundle on the product listing.

Garmin Descent X10

Essential information, easy to read. A 2.1-inch backlit display, scuba/apnea/gauge modes and up to 50 hours of rechargeable dive time make the X10 worth considering for straightforward diving. Its simulator in Garmin Dive helps you learn the controls before entering the water.

100 m dive rating. No air integration. Ask us about U.S. stock and configuration. Garmin X10 details.

Garmin Descent X30

Color readability and physical controls. The 2.4-inch LCD, four large buttons and reversible screen orientation suit divers who want a dedicated format. Surface GPS records entry and exit points; the digital compass supports underwater bearings.

100 m dive rating, up to 30 hours at medium brightness, and multi-gas/trimix support. It is not the air-integrated X50i. Garmin X30 specifications.

Garmin Descent X50i

A large display for a connected dive setup. The 3-inch color touchscreen, 200 m dive rating, CCR support and DiveView maps distinguish the X50i. Supports up to 8 T2 transmitters (sold separately) for air integration and SubWave messaging.

The surface-team accessory. Links a compatible Garmin dive network to the topside crew through Garmin Dive. Supports monitoring and preset messaging for up to eight equipped divers, plus a return-to-buoy reference.
