Fisher Gold Bug 2 Metal Detector (for sale, repair or parts)

A guy traded this in toward something I sold him. He purchased this Fisher Gold Bug 2 Metal Detector about 3 years ago (no longer under warranty). Something happened to the hi/low mineralization switch and he seemed to think the thing was to just glue it in place at the time. It needs replaced and the glue area somehow cleaned away. This metal detector works other than that, seems to have good depth and all. Signs of extensive use are evident. I will be selling it as-is for parts or repair. Peace,
