I currently use Handy Man Nail FinderS3019-HLumber that I got on Amz, and I hate it. It is the wand type, and if you move it fast, it false positives. The only way I find true positives is if I take 1-2 minutes to scan each side of the board. I'm dealing with reclaimed lumber so I have to be diligent. Looking for something a little more accurate and faster for scanning wood for metal.
