  • More sports apps, such as golfing and skiing, mean more ways to play.
  • This smart dive computer features Garmin Pay contactless payments, music storage and notifications.
  • Share and review dives in the Garmin Dive app.
  • Battery life doesn’t limit you. Up to 7 days in smartwatch mode.

DIVE MODES

Get multiple dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather.

CUSTOMIZABLE DIVE MODES

Add additional screens for each dive mode that features the fields you want to see.

SURFACE MULTI-GNSS

Track your entry and exit points with advanced satellite connectivity.

DIVE LOG

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

COMPATIBLE WITH INREACH

Pair with inReach satellite communicators and the inReach dive case (each sold separately)

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.

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.
