Hello, just purchased a used Conquistador from Detector Depot online. It was advertised as having a scuff cover on it. This detector has the white 9x8 concentric spoked coil. When I removed the scuff cover from the coil it appears that the bottom half of the coli itself is missing and the scuff cover was merely hiding the fact. I shouldn't see the brown coil filler that they use after removing the scuff cover should I? This is the pits.
