I should've asked this last night. I'm doing a recovery job this morning and it is INDOORS in an ATTIC. I'm trying to find a wedding band. I have my Garret Pro pointer, AT Pro, and my Whites DFX 300. Any idea what the best settings would be on the AT Pro or Whites DFX would be that would discriminate the sheetrock screws/nails and copper wire that I'm sure are going to be everywhere? The big dummy thanks you in advance.
