a good place to use medal detectors is on a beach. i went to th state park beach during winter a couple years back to try out the boys medal detectors and on my first two finds i sifted a dine and a penny on one and on the second a ring(cheapo though,,tarnished bad)anyway,a park ranger told us that it was not legal to dig on state property and ask us to leave..i tried to explain we was'nt planning to dig up the grass or anywhere near it and that we would smooth the sand back out and he said no dice,so we had to go..any one have a place like a beach where a lot of people hangout in the summer,you might find some valuables someone lost
