The Descent Mk3i is Garmin's flagship dive computer in watch form, built for divers who also train and navigate on land. The 51mm titanium-and-plastic case holds a 1.4-inch AMOLED screen under sapphire glass, and it adds SubWave sonar messaging so paired divers can send preset messages and see each other's distance underwater. It also carries full multisport and fitness tracking, air integration for tank pressure, and up to 600 hours of battery in dive mode. It is big and heavy on the wrist, and its feature set is far beyond what a casual snorkeler needs, but for technical and frequent divers it replaces a dedicated dive computer and a sports watch in one.

Owners and reviewers treat the Descent Mk3i as a serious dive computer that doubles as a capable everyday sports watch. Divers praise the bright screen, air integration and buddy messaging; the main complaints are size, weight and the learning curve of the menus.
