I just finished watching the latest episode of American Diggers. They were granted permission to search the grounds of a beautiful Antebellum home In South Carolina. The very first signal that was dug was on a nice green lawn. The signal was dug with a shovel and uncovered a flattened beer can which was immediately flung away like a Frisbee. If they cannot follow the Treasure Hunters code of ethic's printed in every manual they could at least not show it on television. This is very damaging to this great hobby.
