Patent abstract
A magnetic compass is provided which features a stationary central pointer which extends outwards to the inside of a rim displaying graduated angular indicia, said rim being integral with a pivoting disc which is magnetically coupled. The central pointer assumes the graphic shape of a craft, such as a ship's hull, the stationary disposition of which offers a more intuitive realization of the directional heading of a vessel with respect to the cardinal axes of a compass.
