My detectors don't work in the house. EMI, nails, ductwork all interfere.
The kid using the Ace 250/350 said he was getting a different signal directing him to an area of carpet along a wall. Also, along the wall, less than 6 inches above the floor, a length of the wall metal heating element. Of course the coin was found right where the detector indicated! So, my take? I'm gonna have to add an Ace 250/350 to the stable so I can do in house detecting!!!!
Seriously, the show is a complete set up. Not only is there is no way any detector would have been readable under those conditions, no one leaves behind items worth tens of thousands of dollars. While in this episode the home's owner told the contractors that there was a rare coin "Lost" in the house even that was unbelievable. The owner said he let his son play with the coin.OK, you let your son play with a rare coin worth thousands of dollars? Who does that? Not even even the rich and stupid do that.
