Works great. Comes in original box w manuals, batteries and 2G SD card. Great for hikers , geocachers, backpacker or hunters that go out of celular service. Can also be loaded with blue chart enabling ocean bottom contours and depths for fishing and marine navigation, I'm using the SD card in my boats current GPS. I just can't find USB cord but it's available online for $15-20. $140 obo Lowrance
