[QUOTE="Candigger, post: 573537, member: 14328"] I have compared in detail a number of Detech coils to Nugget Finder and found none of them to be truly competitive. The explanation is simple. NF coils are build with a superior quality cables that happen to be very important to the performance of the GPX machines. As far as the Detech 18"CC is concern it can never be a competition to NF 19" Mono or any other Mono down to 18" sizes simply, because the GPX in its design limits the depth when there is a receiving loop in the coil system. The reason is the added parasitic capacitance of the receiving loop and the connecting cable. The concentric will always be better in ground handling and EMI, but not in depth unless the CC design includes the option of electrically removing and compensating the RX so the CC can work as pure Mono coil, which is not a feature of Detech coils.
