Clinometer Handle Compass is a bringing forth of an antique Clinometer compass. The Handle Compass gets its name from its "handle" shaped sight, which literally serves two purposes: With the compass level, an object can be viewed by the peep sights to judge its magnetic heading. When tilting the compass on its side and viewing an object through the sights, its angle of altitude or declination can be found. A weighted unconvincing arm beneath the compass needle can be make out from one of three scales: Angle in degrees beneath the zenith (from straight up), angle in degrees of elevation or tilting and in inches per yard of slope. The compass has a needle lift mechanism to defend the compass jewel and the undecided arm when being transported.
