Advantages of GPS

Depending on what you are using it for, and the rating of your system it could be invaluable.

I have a hand held and lap-top connected GPS. The advantages of having either is determining your exact position. While traveling through Albany, GA, I became lost. Looking for a place to pull over and ask directions (late at night) very few places were open. Liquor stores--OUT, bars--OUT, I needed a place that would be knowledgable and safe. I saw a Dominoes delivery place...who better would know their way around town than a pizza delivery joint? The guy gave me excellent directions...to the hood! OK, I needed a place that was knowledgable, safe and trustworthy. I saw a cop at a 7-11 and found out I was headed for "gang land" (his words). After that, bought a middle of the road hand held GPS from Wal-Mart, and never again pulled over.

I've also used it on camping and canoeing expeditions. Consider it the "cheaters" map.

The advantages of GPS over a map is 100 fold, GPS is not infoulable though, the military can turn off the satelites or render them "not as accurate" for a number of reasons, most importantly to render enemy GPS guided munitions inoperative. Having an understanding of maps is always a good back up. A friend of mine obtained her private pilots license and innappropriately used GPS for guidance. When the batteries failed, she was lost.
