I'm asking $60 US for this GPS that has been used sparingly and is in mint condidtion. Like most of the others, the Eagle Explorer is a 12-channel receiver. The Explorer’s four AA batteries last up to 20 hours, with the internal battery backup maintaining your saved position points up to10 years without batteries. Explorer's TrailGuide SteerScreen™ shows your present course and position in the center of a compass ring on the screen. To reach your destination, all you have to do is align the solid "path" line with the dotted bearing line. Additional navigation information such as distance traveled, how fast you are going, and estimated time of arrival are all accessible from the Explorer's simple menus and screens. (We still recommend a compass!) Other features of the Explorer include storage capability for up to 750 position points (up to 250 waypoints and 500 graphic icon location symbols). Fifteen different graphic symbols are available to represent specific locations such as campsites, trails, or vehicles.
