Just used my GPS on Tuesday to get me to a site where a house used to be about a hundred years ago. I didn't find any foundation or anything else except for some farm impements but it is fun to use the GPS and having it indicate you are right about where the house used to be. Mine is accurate to within about 20 feet and in pedestrian mode it counts off the feet to the destination as I am walking and directs me to go this way or that way. Ok, I admit it, I am a gadget junkie. But I did find a 12 gram gold ring earlier this summer by using the GPS to get me to a particular spot in a thousand acre field. Mostly pure luck but I wouldn't have been in that area had it not been for my GPS and using map overlays. At times I have GPS'ed myself really deep into the woods. I feel like Lewis and Clark with a magical compass.
