Follow the instrument-like HSI course needle to your destination, so you can easily see if you’re left or right of your desired flight path.

Check Pulse Ox³ to gain awareness of how well your body’s oxygen levels are adjusting to the thinner air at higher altitudes.

View runway orientation (including wind components¹), lengths and airport frequencies as you approach your destination.

See when you’ve reached your desired altitude — or get a vibration alert when you reach an altitude where supplemental oxygen may be required.

Automatically start tracking flights on takeoff. Then automatically transfer date, duration, total flight time and route to your flyGarmin.com^® account¹.

Activate to see your best glide speed, estimated glide distance and glide time during an engine-related issue. View a bearing pointer to the nearest airport, and see a list of alternate airports.

Log a 2-minute session to record key stats, including heart rate⁴, heart rate variability, Pulse Ox, respiration and stress. Then generate a report with those stats to share via the Garmin Connect^™ app on your compatible smartphone.

Optimize your body’s energy reserves, using heart rate variability, stress, sleep and other data to gauge when you’re ready to be active or when you may need to rest.

The watch constantly samples your heart rate 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.

Heart rate variability is used to calculate your stress level score, so you can see if you’re having a calm, balanced or stressful day.

Get a score for your sleep’s quality and insights on how you can do better. Even keep track of the different sleep stages as well as heart rate, stress, Pulse Ox and respiration.

See how you’re breathing throughout the day, during sleep and during breathwork and yoga activities.

Log your daily fluid intake as a reminder to stay hydrated. You can even have an auto goal for hydration that adjusts based on how much you sweat during activities.
