The instrument is specially designed to determine dip angle and azimuth angle of borehole. It is suitable to determine dip angle and azimuth angle at fixed points in the non-magnetic borehole, which is more than 46 mm in diameter.
It is not required to use outer power supply and cable. You can make determination only using wire rope.
