Minelab Ferrite GPZ 7000 Metal Detector Ground Balance Accessory XP ORX This coil is made forMinelab Ferrite GPZ 7000 Metal Detector Ground Balance Accessory To achieve optimum ground balance, the GPZ 7000 requires as much different data about the ground as possible, especially variations in soil mineralization. Ground balancing using a ferrite means that less soil needs to be covered during the initial ground balance period because the ferrite artificially adds very useful data to assist in achieving an accurate ground balance.
