YOU’RE A DIVER UNDERNEATH

Land or sea, this compact dive computer is built for both of your worlds.

Support for multiple dive modes — ranging from technical to free dives.

GPS enabled to help mark surface entry and exit points.

Store up to 200 dives. Upload, share and review dives in the Garmin Dive app¹.

Measure your performance, and track your stats above water.

Track your activities with more than 30 built-in sports apps and advanced training features.

Explore longer with up to 25 hours in dive mode, 21 days in smartwatch mode and 26 hours in GPS mode.

ENGINEERED FOR ENDURANCE

This rugged dive computer is water-rated to 100 meters, features a sapphire lens and is rated to MIL-STD-810.

DESIGNED TO BE DARING

With a high-contrast display and purpose-built design, this device is meant to wow you.

Deep Feature Set

DIVE MODES

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

SURFACE MULTI-GNSS

Track your entry and exit points² with advanced satellite connectivity.

DIVE LOG

Store and review data for up to 200 dives — and share via the Garmin Dive app¹.

CUSTOMIZABLE DIVE MODES

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

COMPATIBLE WITH INREACH

Pair with inReach satellite communicators² and the inReach dive case (each sold separately).

DIVE COMPASS

Easily navigate below the waterline with the built-in 3-axis compass.

TIDE DATA

Stay up to date on ocean conditions so you can catch the perfect wave. Just pair the watch with your compatible smartphone.

SURFLINE

See conditions — such as tide, wave height, wind and surf rating — for each of the five nearest surf spots, when paired with the Garmin Connect app on your compatible smartphone.

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.

FITNESS AGE

This feature uses chronological age, your weekly vigorous activity and resting heart rate to estimate if your body is younger or older than you are. And you can get tips to lower your fitness age.

RECOVERY TIME

After each workout, recovery time lets you know when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep.

TRAINING STATUS

This metric evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching.

DAILY SUGGESTED WORKOUTS

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

ALL-DAY RESPIRATION

Track how you’re breathing throughout the day, during sleep, and during breathwork.

Tune in to your body and mind.

SLEEP SCORE AND ADVANCED SLEEP MONITORING

Get a full breakdown of your light, deep and REM sleep stages. View it all on a dedicated widget that includes your sleep score and insights.

INTENSITY MINUTES

With improvements based on guidance from the CDC and WHO, now you can understand when you’ve earned daily intensity minutes and during what activity.

BODY BATTERY ENERGY MONITORING

Track your body’s energy levels so you can find the best times for activity and rest.

HYDRATION TRACKING

Log daily fluid intake as a reminder to stay hydrated. When auto goal is enabled, you’ll even see estimated sweat loss after an activity, and your goal will adjust accordingly.

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.

WRIST-BASED HEART RATE

The watch constantly samples your heart rate⁴ and will alert you if it stays too high or too low while you’re at rest. It also helps gauge how hard you work during activities — even while swimming.

Designed for both your worlds.

SUPERIOR BUILD QUALITY

Enjoy a rugged, watch-style dive computer with a sapphire lens, silicone bands and an easy-to-read monochrome display.

SMART NOTIFICATIONS

Receive emails, texts and alerts right on your wrist when paired with a compatible device.

BATTERY LIFE

Stay in the water longer with up to 25 hours in dive mode, 21 days in smartwatch mode and 26 hours in GPS mode.

When your watch and phone are paired, your live location can be sent to your contacts manually or — during select outdoor activities — automatically with built-in incident detection⁵.
