What do you guys & gals use for detecting nails and other unwanted bits of metal in wood :?: I have a huge stock of old wooden beams, planks, and various other types of wood which all have some or a lot of nails etc. buried within. Any advice on makes, good or bad, cost, and of course where in U.K. they can be purchased. I have a contact in England who can obtain for me. Thanks in advance.
