Mirror Compass

measurement of direction and inclination

Spiegelkompass

The Mirror Compass is based on the normal Geologist’s Compass. As an additional feature it offers the possibility to measure direction and inclination when performing topographic surveys, short traverses, or to orient oneself in open terrain.

leather case dimensions (mm) 120 x 100 x 45 mm

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.

There is a mirror on the inside of the compass cover which can be used to observe the compass needle and the graduated circle. The small lateral viewfinder can be utilized to measure direction and inclination when performing topographic surveys. It is also possible to sight landmarks in the distance that are above or under the observer’s own altitude. Furthermore, there is a cap on the lower side of the compass that can be removed to mount the instrument on a standard camera tripod.

  • sapphire bearing
  • mirror on the inside of the compass cover which can be used to observe the compass needle and the graduated circle
  • notch and bead sighter
  • small lateral viewfinder to sight landmarks in the distance that are above or under the observer’s own altitude, measurement of direction and inclination when performing topographic surveys, high targeting accuracy, sighting a landmark is not influenced by the eye’s accommodation
  • 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 spirit level for measurements at places that are difficult to access
  • metal cover to protect the cover glass and to measure inclination
  • leather case
