The economical Foretrex 101 Portable Navigator is the wrist-mount GPS that frees up your hands so you can focus on your outdoor activities. The Foretrex 101 Portable Navigator features PC interface capabilities for downloading waypoints, tracks and routes, but operates on two AAA batteries. It's easy-to-use interface and basic GPS capabilities are perfect for outdoor enthusiasts who would rather replace the batteries than recharge the unit in the field. This unit features Garmin's intuitive operating logic, utilizing six dedicated buttons to simplify navigation. Whether it's a campsite, deer stand, or other place of interest, users can mark its location, identify the waypoint, and navigate to it later using the GoTo function. Also, with the help of Garmin's exclusive TracBack technology, users can retrace their steps by following an electronic breadcrumb trail back to their original starting point.
