so I am all hyped up about becoming rich by looking for treasure. I tried it in the house, it beeps at everything, except my cat. Anyways, took it to the not so popular beach with lots of sand. After an hour of sweeeping, I found a key to someones house, it looked like it's been there for couple of years, so am not sure how to locate the owner. Anyways, tried it on my silver ring, it does has a tone to it. Hopes still high. After another field test, am sure it'll be more reward. Good product, but hard to overcome the fear of looking like an outcast with that thing in public beaches with people around. Maybe I should dress up like a hobo, will it help?
