Move the detector slowly back and forth, then up and down as you find the exact spot where the metal resides. Many metal detectors even have breakdowns of metal type or potentially coin worth. Work slowly, reading the face of the metal detector as you learn how to use it. 3. Cut out any objects in a "plug."
