Garmin Descent Mk1, Gray Sapphire with DLC Titanium Band - Versatile GPS Dive Computer for Your Diving Adventures. Whether you dive with or without tanks, in saltwater or fresh water, breathing nitrox, trimix or holding your breath - Descent Mk1 is the intuitive, do-it-all dive computer you've been waiting for. It's the first watch-sized dive computer to offer surface GPS navigation with full-color onscreen mapping and location reference - so you can easily mark your dive entry and exit points. Once underwater, the proven Bühlmann ZHL-16c algorithm makes sure you're staying within your dive limits. Selectable tone and vibration alerts help keep you informed while you're submerged. Returning topside, Descent Mk1 also functions as a robust training companion, offering the best features of our fēnix 5X ultimate multisport GPS watch, including smart notifications to help you stay in touch on the go. What's more, the Descent Mk1 design is so sleek, comfortable and elegantly crafted, you'll want to wear it as your everyday timepiece. By Garmin.
