Versatile GPS Dive Computer for Your Diving Adventures

Premium full-featured GPS dive computer in a sleek watch-style design; with bright 1.2” color display and mapping
Built-in sensors include 3-axis compass, gyroscope and barometric altimeter as well as GPS and GLONASS capability that lets you mark your dive entry and exit points¹ for surface navigation
Choose modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, closed circuit rebreather (CCR); plan your dives directly on the device
Dive log lets you store and review data from up to 200 dives — and share online via Garmin Connect™ and its included mobile app
Features Elevate™ wrist heart rate technology² with multisport activity profiles, performance metrics and smart notifications³
Battery life: up to 18 days in watch mode, 10 days in smartwatch mode, 36 hours in dive mode and 20 hours in GPS mode⁴

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 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.

Breathe Easier, Dive Better

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” color 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.

Multiple Navigation Sensors

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.

Wrist-based Heart Rate

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.

Advanced Multisport Watch Features

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.

Smart Connectivity

When paired with your compatible smartphone³, Descent Mk1 makes it easy to receive text messages, emails and smart notifications right on your watch face. It also gives you access to automatic uploads with Garmin Connect, audio prompts, music controls and more. While you’re topside, friends and family members can follow your location and adventures online, in real time, using the LiveTrack feature. Or you can use GroupTrack and your map display to keep tabs on your activity-sharing buddies as you go.

Charge It Up, Change It Up

Between charges, you can count on up to 36 hours of battery life in dive mode, up to 18 days in watch mode, up to 10 days in smartwatch mode and up to 20 hours in GPS mode (all depending on settings). QuickFit®bands let you tailor your wrist-worn style for any daily activity or special occasion — no tools required. And for diving, longer QuickFit® straps are included for use over thick wetsuits or dry suits.

You can customize the watch display with free watch faces, apps and data fields from our Connect IQ™ store. For your safety, Connect IQ functions are not available while diving, so we can ensure that all dive capabilities are functioning as they were designed. Both Descent Mk1 models are also Wi-Fi®-enabled, so each can connect to your wireless network and automatically send activity uploads for sharing on Garmin Connect.
