GPS is the one tool after a good set of binos and your rifle that is a must have for me anymore. All the reaons mentioned are why I carry one, into the unknown AND the known. Got stuck in a whiteout last year during the off season rabbit hunting. I f I hadn'lt had mine, you wouldn't be hearing from me right now.

I got the Delorme set up on maps on CD, and generally like it. I have compared it to some hard copy maps I have, and they do miss some tiny trails that sho won older maps, but as for the contours, landmarks, vegetation etc... not much changes there.

I scout withthe GPS, and back to set the coordinates in the map maker, see where I have been and make copies when I am ready to head out for the hunt. One of the best tools you can get.

I wil lsay though, the Natl Geo set up is probably the better, having looked at it and compared, but not unhappy with what I got.
