  • facilitates direction and inclination measurements for reconnaissance
  • the measurement of minor compass traverses
  • orientation in the terrain
  • General field-geological work

The following features serve to extend the field of application:


  • Mirror on the internal surface of the dip measuring plate for observing and reading the magnetic needle and graduated circle for different targets
  • Notch and bead sights for nearly horizontal sightings in the terrain
  • Collimator sighting arrangement
    • for any inclined aiming at terrain spots
    • for the direct combination of inclination and direction measurements for topographic sighting
    • high pointing accuracy
    • thanks to the collimation principle the sighting is independent of the power of accommodation of the observer's eyes
    • easy to detach if not used
  • Ground magnetic needle placed on edge
  • Permanent locking of the magnetic system - can be released during measurement by depressing the push-button and should be used for shortening the setting time
  • Easy adjustment of the graduated circle
  • Lockable inclinometer for inclination measurements of high accuracy
  • Colour coding on circle of altitude and magnetic needle (according to Clar) - unambiguous determination of the direction of dip of geological formations
  • Circular spirit level for levelling, lateral glass tube for measurement at points of difficult access


  • Dip measuring plate
  • reading of dip angle
  • protection for the glass cover

Available with printed or engraved vertical scale
