The Descent Mk3i 43mm is Garmin's dive computer in a smaller, everyday-wearable case. It pairs air-integrated tank pressure (with a compatible transmitter) and dive logging with full multisport GPS watch features: AMOLED screen, sapphire glass, 200m water resistance and 32GB storage. It suits divers who want one watch for the water and the gym, and it is smaller and lighter than the 51mm Mk3i. Reviewers rate the dive modes and air integration highly but note the plastic case and the premium tier it sits in against cheaper dive computers and the larger model.

Divers praise the readable AMOLED screen, accurate depth and air-integration data, and the convenience of a full sports watch alongside dive modes. Complaints focus on the plastic case, the cost of adding a transmitter and shorter battery life than the bigger model.
