Applications and Feature
It is mainly used for borehole magnetic prospecting. It is applicable for the measurements of horizontal components (X, Y) and vertical component (Z) of the magnetic field in the borehole greater than φ46mm. In addition, it is used as the high-precision teleclinometer without magnetic hole or away from the magnetic well.
