I've had this with my hiking gear for a while now and love it. Never been dropped, scratched, or altered other than adding a screen protector when it came out of the box. TopoActive maps for navigation and guidance. It's a great little unit and can do more than just basic maps, tracks, and waypoints. Practically new out of box. Uses two AA batteries and can support a 32G micro SD card for additional maps/images/aerials. Includes an extra screen protector.
