Geologist’s Compass

without mirror

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.

The casing of the compass has a modern appearance and thanks to its design 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 clinometer. The declination can easily and quickly be set by the user. A small movable copper weight is fitted to the magnetic needle to compensate for inclination.

The instrument can be correctly leveled 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.

  • sapphire bearing
  • magnetic needle placed on edge
  • release and lock button for the needle
  • graduated circles can be easily adjusted
  • lockable pendulum clinometer for inclination measurements of high accuracy
  • circular bubble level for leveling
  • lateral bubble level for measurements at places that are difficult to access
  • declination and inclination can be easily set to the specific parameters of the user’s current location
