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 more5.

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 rate6 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 Ox6 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 stages5 as well as Pulse Ox6 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 Store7.
