Abstract

A compass which is used for pedestrian activities is mounted on a base (1) of transparent material containing a magnifying lens (2) and a circular housing (5). A cylindrical compass body (6) has a diameter which corresponds with the internal diameter of the housing to allow it to be rotated. A protrusion (7) with a hole (8) receives a screw (9) which passes through a loop (16) in the U-shaped flexible clip (12). The two arms (13, 14) of the clip engage in a groove (11) in the compass body through a slot (4) which extends for 180 degs. in the housing.
