New basic stratum compass with clinometer to measure azimuth of dip and angle of dip in one step.
Geological Compasses / Clar Compasses
Developed by Eberhard Clar in 1954, the advantage of the modern geological compass was that – strike and dip be measured in a single step, leveraging the vertical circle for dip angle and the compass for the strike direction. It features a unique lid design that can swing 360 degrees in both directions, two axes that allow the measurement of precise horizontal and vertical angles on all bedding surfaces configurations.
It appears confusing, initially, to the novice user, as the numerics on the geological compass dial ascend anticlockwise-wise. This happens because the compass is accustomed to determining dip and dip-direction of surfaces, and plunge and plunge-direction of lines.
