When you can rely on Instinct, the world can rely on you. This rugged, reliable outdoor GPS watch is built to the U.S. military standard 810G for thermal, shock and water resistance (rated to 100 meters). The fiber-reinforced polymer case adds strength and durability, and the chemically strengthened, scratch-resistant display is high-contrast enough to read in bright sunlight, so you can take it with you into the extremes you face every day. You've never been one to follow the beaten path - that's where Instinct comes in. GPS, GLONASS and Galileo satellite network capability tracks in more challenging environments than GPS alone. The built-in 3-axis compass and barometric altimeter help you keep your bearings. Take the guesswork out of your return journey by using the TracBack feature to navigate the same route back to start. The Instinct GPS watch monitors your heart rate, activity and stress throughout the day, so you know how much you do - and how hard you're working to do it. When you're ready to train, Garmin has got you covered with preloaded activity profiles for running, biking, swimming and more.
