So, "global positioning systems"

I need a GPS. Seriously. I'm so good at getting lost, I consider it a talent. Now I find myself looking at Lowrance items, and I never realized there were so many variations on these magical direction-finding machines. Waterproof GPS for the outdoorsman! Hunting-specific graphics for the hunter guy! Mp3 player! Broadband! Marine GPS devices that will tell a fisherman where the fish are!
