COMPASS OVERVIEW

A compass is a navigational instrument for finding directions on the earth. It consists of a magnetized pointer free to align itself accurately with Earth's magnetic field, which is of great assistance in navigation. The cardinal points are north, south, east and west.

Pictured below are two different types of compasses.  The compass at left is a Brunton compass used by geologists and others for many specialized mapping purposes.  On the right is a more common type of compass used for general orienteering and some mapping purposes.
