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-colour onscreen mapping and location reference — so you can easily mark your dive entry and exit points¹.
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® 5Xultimate multisport GPS watch, including smart notifications³ 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.
Providing easy-to-access features for a range of diving activities — including the ability to plan dives on the device for recreational, technical and free diving — Descent Mk1 provides all the key, real-time data you need for a confident dive. The computer is automatically activated when you hit the water, showing your current depth, dive time, water temperature, ascent/descent rate, no-deco time, decompression stop information, battery life and more on the unit’s crisp 1.2” colour display.You can set the audible tone and vibration alarms to provide reminders at critical points in your dive. And up to 6 different gas mixes are supported, including nitrox and trimix (up to 100% oxygen). Configurable conservatism settings let you adjust your personal safety limits.
In addition to its high-sensitivity GPS and GLONASS satellite tracking for map-based surface navigation, Descent Mk1 also provides a full array of ABC (altimeter, barometer and compass) sensor capabilities for topside navigation. And the easy-to-read compass display is available for underwater use as well. The built-in altimeter provides elevation data, while the tilt-compensated 3-axis electronic compass keeps your bearing — whether you’re moving or not. For quick access to the compass display, a handy “tap to compass” feature lets you simply double-tap the screen instead of pushing the function buttons.
The Descent Mk1 dive computer uses Garmin Elevate wrist-based heart rate technology² to optically scan your pulse (when worn in contact with your skin, not over a wetsuit or dry suit). The dive computer tracks your exertion levels and uploads your heart rate data automatically to your Garmin Connect online account for post-dive review and analysis.
Beyond its full range of dive computer functions, Descent Mk1 also offers a complete feature set of sports/training, fitness and outdoor navigation tools, leveraged from our popular fēnix line of high-end multisport watches. You can tap into an array of physiological metrics, running dynamics, fitness tracking features and more — to monitor your workout stats, measure your progress and help avoid injury. Special preloaded activity profiles are provided for swimming, running, biking, hiking, skiing, rowing, paddle boarding and more. Various timekeeping, lap counts and map tracking functions are easily accessible. Plus, for added motivation, you can even download advanced workouts and training plans to your device from Garmin Connect.
