I saw an episode the other night, it was ok I guess. There was part that made me scratch my head though. The guys were inside an old abandoned house (plantation house?), and they located a hole in the dirt a few feet in front of the fireplace. Buddy puts his coil over the dirt and the narrator says "this metal detector is so sensitive, it will locate treasure ten feet deep".
I didn't catch the brand of detector, maybe a Fisher, but it was a regular style detector. Ten feet deep? Am I missing something, or is this inaccurate?
