I am moving on and cleaning out garage and have a Gary PI detector that I built. It works great. Only thing different is I plug in a meter (included) instead of the headphone. I can barely detect a 1 oz gold coin at 33 inches with it in air. I think the coil is about 18 inches. Also includes a 12 volt gelcell battery and carrying case for battery and electronics.
Asking $120 plus shipping.
