Explore both of your worlds underwater and topside with Descent Mk2S. This smaller watch-sized dive computer features multiple dive modes, such as single and multiple gas dives, gauge, apnea, apnea hunt and closed-circuit rebreather. Descent Mk2S also comes with an underwater 3-axis compass as well as surface GPS capabilities to mark your entry and exit points. On land, Descent Mk2S doubles as a premium multisport GPS smartwatch with multiple sports apps, estimated wrist-based heart rate monitoring, Pulse Ox (this is not a medical device and is not intended for use in the diagnosis or monitoring of any medical condition) sensor and advanced training features. It also offers Garmin Pay contactless payments (not all countries and payment networks are eligible), music storage and smart notifications (when paired with a compatible smartphone) and can fit any style with your interchangeable QuickFit bands.
