The Garmin Instinct E is made for the great outdoors. It's tested to U.S. military standards for thermal, shock, and water resistance (10 ATM). And the tough case and scratch-resistant lens help maintain its rugged good looks. If you're heading out to the wilderness there's an altimeter, barometer, and 3-axis electronic compass to keep you on track. Plus, you can log your activities, such as running, cycling, and hiking to build up a general picture of your fitness.Good to know- Keep tabs on your health with heart rate, sleep, Pulse Ox monitoring and more- Send your saved locations, courses, and workouts to a friend's devices with Garmin Share- Customise your watch face, data, and apps in the Connect IQ Store- Share your location with loved ones with incident detection and Assistance safety features
