Geologist's Compass
· General field-geological work
· Special structural-geological,deposit-tectonic, and engineering-geological rockmechanical work
· Can be used for route surveying, for the survey of natural and artificial openings above and below ground
· For staking out and dimensioning holes
· For the transfer of geological data into maps and plans
· Rockwork as well as moderate-accuracy surveying
· 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 - for each measuring technique and for setting declination values of any magnitude
· 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
