I had my gt for three weeks now i have been detecting only dry and wet sand so far i have coin total of $32.58 and two silver rings with somekind if ice on it and one electro plated white gold with stones on my todays hunt as i was returning home a young kid about 15 16 years old aproached me he said he had lost his gold cross charm i had agreed to help him after two minutes of searching i had a nice soft but weak signal, after locating the charm i noticed that it was only about three inches under the dry sand my question is. i can pull a dime or a penny at 10 to 12 inches on a wet sand, how come the gold was very weak it was like a faint signal what am i doing wrong? oh at the and of finding the gold charm the boys big brother handed me $5.00 bucks a good day. I'm getting a new camera i will post pictures from now on soon.
