Stay on track with the tactical edition of the Instinct Outdoor GPS Watch from Garmin. The Instinct features a built-in 3-axis compass, barometric altimeter, and access to GPS, GLONASS, and Galileo. Using multiple global positioning systems can help provide you with higher accuracy than GPS alone. When you're out on your adventures, you can rely on the Instinct's rugged construction, which supports the 0U.S. 810G military standard for thermal, shock, and water resistance. In fact, the Instinct is water-resistant up to 100m.
