Abstract
A recreational or outdoor compass is comprised of a base member and a vial assembly pivotally coupled to said base member. The vial assembly comprises a vial with an orienting marker and a magnetized indicator member journaled in the vial and pointing to magnetic north, the indicator member having through hole. The orienting marker has an outer contour, wherein the shape of the outer contour of the orienting marker essentially corresponds to the shape of the inner contour of the through hole, such that the outer contour of the orienting marker virtually matches the inner contour of the through hole when pointing northwards.
