Is it possible for cell phones to create interference with your MD if you are carrying your phone and it's on while you detect? What about a magnet that is part of the phone case?? Any harm done if the two are too close???
i think i've heard of people having interference with phones, also some pinpointers can cause interference ( i think the vibra probe was one but i forget on what machine). not sure about damage to the phone with a magnet but i do know that your propointer will mess up the magnetic strip on credit cards...so don't put your propointer in the same pocket with your wallet
