Suitable for GPX and older GP and SD series metal detectors. The 11 Double-D has a great blend of stability, depth and sensitivity and is very stable in all ground types.Being a Double-D coil it can be used with the Iron Reject and RX cancel features making it a great relic coil. Use Commander Coils to get best performance from your GPX metal detector. Minelab Commander Coils have been designed by Minelab's team of scientists and engineers for optimum performance and to meet the precise requirements of MPS technology. Commander Coils are well made, robust and designed to excel in the rugged conditions of the goldfields. They are manufactured using high quality components, including gold plated plugs, low-noise shielded cable and multi-strand Litz wire.
This special Litz wire has an advantage over other wire because its high surface area gives greater transmission ability. This results in more powerful, sensitive and energy efficient coils.
