Garmin Descent MK3I 51 MM

This next-generation air-integrated Descent dive computer adds new features such as an integrated LED flashlight, preloaded color bathymetric depth maps of over 4,000 dive sites, and a dive-readiness assessment tool that utilizes the computer’s fitness-and sport-tracking capabilities to ensure you’re prepared to dive. Using subwave sonar technology, it can monitor tank information and depth of up to eight tanks. When using the new T2 transmitter/transceiver, it can even be used to communicate with other Mk3i computers via preformatted messages. It has a 1.4-inch full color display and a built-in battery that delivers up to 66 hours of dive time on a single charge. It includes the same technical dive modes as previous Descent models and is compatible with Garmin inReach satellite communicators.
