Pete;
I am still in a learning mode but I agree with all you have said. I used to do a lot of deer hunting and more than once I found myself lost in the woods even though I carried an antiquated magnetic coumpass. Being right handed I have come across my own tracks in the snow while attempeting to walk a straight line only to discover that my natural clockwise walking rotation ultimently catches up with me. Another benifit is it will display with a degree of acturatcy the names off all the streets you approach while driving. And if programed correctly it will show the names of all eaterys, gas stations, businesses, and anything else of value near to your location.
How did I ever live without it? Will it work well with the almost flat windshield in my P-15?
