Original Freiberg geological compass, type B with mirror and inclinometer, engraved, 1 piece.

The geologist compass has a mirror on the inside of the lid. It includes a rear sight and a front sight. It is equipped with a pendulum clinometer with which you can make inclination measurements with high accuracy.
The declination value can be adjusted by means of a gear wheel. To eliminate the inclination, the needle is equipped with a sliding copper weight.
The leveling is possible by the attached circular and tubular bubble. Locking of the magnetic system is possible. The graduated circles can be easily adjusted. With drop measuring plate to protect the cover glass as for measuring drop angles.
