Surface Multi-GNSS

Dive Log
Store and review data for up to 200 dives - and share via the Garmin Dive app.

Push performance to a whole new level

Sports Apps
Use preloaded activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, golfing and more.

Surf-Ready Features
Get ready to catch some waves. Use the Surfline Sessions app on your compatible smartphone with your paired Descent Mk2S dive computer to create a video of every wave you ride in front of your Surfline camera. Watch the videos later to see how you did.

Backcountry Ski
Stay informed when you're in the snow. This preloaded profile can distinguish between skiing and climbing. It automatically shows metrics specific to either ascent or descent.

XC Ski Dynamics
When paired with the HRM-Pro chest strap (sold separately), the ski power metric helps measure the actual exercise load of cross-country workouts.

MTB Dynamics
Track the details of every ride with mountain biking metrics plus specialized grit and flow measurements that rate trail difficulty and how smoothly you descend, giving you a score to beat next time.

Performance Metrics
View advanced training metrics that include running dynamics, heat- and altitude-adjusted VO2 max, recovery advisor and more.

Trail Run VO2 Max
Trail run VO2 max tracks your cardiovascular fitness level and adjusts based on trail conditions.

Recovery Advisor
Giving your body time to recover between training sessions is crucial. After each workout, the built-in recovery advisor will let you know how long to rest before another big effort.

Daily Suggested Workouts
For training guidance that takes you and your fitness level into account, get daily run and ride suggestions based on your current training load and status.

Animated Workouts
Easily follow animated workouts for cardio, strength, yoga and Pilates. View workouts right on your watch screen.

Wrist-Based Heart Rate
Optical heart rate technology gauges activity intensity as well as heart rate variability to calculate your stress level. It also tracks underwater without a heart rate strap.

Pulse Ox Sensor
For altitude acclimation or sleep monitoring, a Pulse Ox sensor uses light beams at your wrist to gauge how well your body is absorbing oxygen.

All Day Respiration
Track how you're breathing throughout the day, during sleep, and during breathwork and activities such as yoga.

Advanced Sleep Monitoring
Get a full breakdown of your light, deep and REM sleep stages as well as Pulse Ox and respiration data. View it all on a dedicated widget that includes your stress score and other insights.

Women's Health Tracking
Use the Garmin Connect app to track your menstrual cycle or pregnancy. Log symptoms, get exercise and nutrition education, and more. See details on your wrist by downloading the Menstrual Cycle Tracking widget and Pregnancy Tracking app from the Connect IQ Store.

You reach new heights. Your watch goes with you

Multi-GNSS Support
Access multiple global navigation systems (GPS, GLONASS and Galileo) to track in more challenging environments than GPS alone.

Topo And Ski Maps
Use topographical maps to navigate your adventures and view run names and difficulty ratings for 2,000 worldwide ski resorts.

ABC Surface Sensors
Navigate your next trail with ABC sensors, including an altimeter for elevation data, barometer to monitor weather and 3-axis compass.

PacePro Technology
A first-of-its-kind PacePro feature helps keep you on pace with grade-adjusted guidance as you run a course.

Turn-By-Turn Navigation
Follow a route or course with help from turn-by-turn directions, which let you know ahead of time when the next turn is coming.

Round-Trip Routing
Enter a distance you want to travel, and get suggested routes that will bring you back to your starting point. Trendline popularity routing helps you find the best local paths.

Store up to 2,000 songs, or access music apps from your compatible services, including Spotify, Deezer and Amazon Music.
