I don't think I understand your question, but here goes -- the researcher used as a working hypothesis that the hiding spots described in the Copper Scroll referred to the Qumran complex, and tested the idea with a metal detector. He hasn't dug up anything (that would require approval by the IAA, and affiliation with a university I'm sure) but has tested his identifications with the tools at hand.
