Compass with improved declination adjustment

摘要

A recreational or outdoor compass (1) is comprised of a base member (2) and a vial assembly (3) pivotally coupled to said base member. The vial assembly comprises a vial (4) and a magnetized indicator member(5) pivotally journaled in the vial and pointing to magnetic north. The vial assembly is further comprised of an azimuth ring indirectly or directly frictionally coupled to the vial and a transparent disc member (7) permanently aligned with the azimuth ring (6) and arranged below the vial. Moreover, the vial assembly comprises a retention means (8) permanently aligned with the azimuth ring, such that holding of the retention means (8) allows to rotate the vial separately from the azimuth ring (6) by exceeding the frictional force.
