Geologist's Compass with Mirror, 360°, Engraved Circle Hinge & Pendulum Inclinometer

The Freiberger Compass is an all-metal, German-made geological compass 
Even in the era of satellite-based positioning systems a compass can still be a useful tool when orienting oneself in a traditional way.
Freiberger Geologist's Compasses are primarily used to measure orientation of geological structures. With the Geologist's Compass you are able to perform measurements of strike directions, dips and angles of pitch, or dipping angles of areal and linear geological elements.

Well proven, for professional use:
  • Sapphire bearing
  • Magnetic needle sharpened, upright
  • Locking of the magnet system possible
  • Easy adjustment of the pitch circles
  • Thanks to the lockable clinometer, inclination measurements with greater accuracy are possible
  • Circular level for leveling
  • Lateral tubular level for measurements in dificult to reach places
  • Declination and inclination can easily be adjusted to the locally applicable values
  • Drop measuring plate as protection of the cover glass and for measuring drop angles
  • Protective bag made of leather

Application:

The casing of the compass has a modern appearance and thanks to its desogn and size it is comfortable and easy to handle. The compass can be used for general geological studies and to measure the orientation of specific geological structures and natural mineral deposits.

It has a pendulum inclinometer. The declination can easily and quickly be set by the user and a small, movable, copper weight is fitted to the magnetic needle to compensate for inclination.


The instrument can be correctly levellled using the circular and the tubular bubble level. The compass lid is used to measure dip direction and it also protects the cover glass when the compass is not used. Lid friction movement is fully adjustable.
