The handle on the 3” Handle Compass works in two ways. When the compass is level, an object can be viewed through the peep sights to determine its magnetic heading. When tilting the compass on its side and viewing an object through its sights, its angle of elevation or declination can be found. A weighted pendulous arm beneath the compass needle can be read from one of three scales: angle in degrees beneath the zenith (from straight up), angle in degrees of elevation or declination, and in inches per yard of slope. This compass also has a needle lift mechanism to protect the compass jewel and the pendulous arm when being transported. The compass can fit in a pocket, and measures 2?” in diameter, is ?” thick, or 2¼” tall with the handle up.
