I have noticed that on a few of my older detectors that the bolt and nut that holds the coil on is metal. The newer ones seem to be plastic. Would there be any advantage of replacing the metal ones with plastic? Also my old Bandido II has a lower rod that is mostly metal and terminates with about 6 inches of plastic. Would a non-metal lower rod help? Does the ground balance cancel out the metal? Would the ground balance be more sensitive if the metal were not there?
