I have two gps, the one for the vehicle is a standard touch screen, with memory, it works nicely. I also have a magellan platinum model I use in the boat as well as when hikeing around, I usaully just mark a way point like where I park. then if I have to I can turn it on and it will point me in the right direction. I have yet had to use it to find my way back, but the peace of mind knowing I have it is very reasuring, its very important that you practice with it, theres never a good time to be pulling out the manual and trying to read it by flash light, because now you need it. The other thing I like about the hand helds is they have a compass, its not magnetic, so like places in the u.p. that will totally screw with you wont matter, or holding next to something metal, like a gun barrell. The only problem I had with the vehicle mounted was when we were in downtown Chicago, The tall buildings were blocking the signal, I thought the thing was going to have a meltdown. The hand helds can eat batteries if you leave them on all the time, I always carry spares, and only turn it on when needed. I have my parking spot, my tree stand and my hunting partners stand marked, just in case....nelson
