Magnetometer GA-52Cx Manual
Magnetometer. The magnetometer detects the magnetic field of a ferromagnetic object. It responds to the difference in the magnetic field between two sensors. It is interpreted in the field by listening to changes in frequency as emitted by a speaker on the device. Larger metallic objects can be located at depths of up to 10’ or more but total depths will depend on the size, type, shape, and orientation of objects along with the amount of interference from other objects.
