The Dive Computer for Both Worlds

This is the smaller, watch-style dive computer that features multiple modes as well as multisport training and smart features.

  • Choose from multiple dive modes for your underwater adventure.
  • Measure your performance, and track your stats above water.
  • More sports apps, such as golfing and skiing, mean more ways to play.
  • This smart dive computer features Garmin Pay™ contactless payments1, music storage and notifications2.
  • Review dives in the Garmin Dive™ app3.
  • Battery life doesn’t limit you. Up to 7 days in smartwatch mode

Plunge to a Whole New Depth of Capability

  • 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 points4 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 communicators4 and the inReach dive case (each sold separately)

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 V02 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.

  • 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.
