Abstract
A compass assembly, a system and a method of using the compass assembly are provided. The compass assembly has a removable marking device attached to one of the legs. The other leg contains a retractable sleeve having a spring and engaging pin therein. In use, pressure is applied to the leg having the sleeve thereby pushing the engaging pin through a hole in the retractable sleeve thereby anchoring the compass and providing a point around which the compass may be spun. The marking device attached to the other leg of the compass may be removed to be changed, replaced or refilled. A marking device with various writing media, such as multiple colors or lead may be attached to the leg. Separate components of the compass may be distinctly colored to provide an instructional aid for using the compass.
