Ground balancing using a ferrite means that less soil needs to be covered during the initial ground balance period.
To achieve optimum ground balance, the Minelab GPZ 7000 requires as much different data about the ground as possible, especially variations in the 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 balance.
