The dimensions of the compass itself are 11/8 centimeters. Made of heavy aluminum alloy

Mountain compass is designed to determine the azimuth and inclination of the line of incidence of the plane of marking of rock samples. It is used in magnetic prospecting, in geological and geographical works to determine the elements of bedding of rock layers.

The compass housing is made of aluminum alloy. The compass has high-strength protective glass. The absence of polymer materials eliminates the effect of electrification on the readings of the magnetic needle, made of 52KF-TM alloy (vicalloy). The northern end of the arrow is white, and the southern end has a copper coil to balance the vertical component of the earth's magnetic field in the northern hemisphere
