Hi, newbie to hunting. I'd like to purchase a gps for my 11 year old son who has some learning disabilities. Because he's young, I don't want to spend a fortune, but I also want to get one that works but is somewhat on the simpler side. Of course, I'll be a part of the hunt and helping him. From what I've read the geomate jr isn't that great, and sometimes you have to buy maps in addition to the gps??? I need someone to just tell me which one to get for my son for Christmas. Any help will be greatly appreciated. Give Thanks! Cherie
