A compass is an essential tool in wilderness survival. Along with a good quality topographical map of the area you're navigating, knowing how to use a compass will ensure that you're never lost. You can learn to identify the basic components of the compass, take an accurate reading of your bearings, and start developing the necessary skills of navigation with a few simple steps.
A compass is a navigational instrument that shows directions in a frame of reference that is stationary relative to the surface of the Earth. The frame of reference defines the four cardinal directions. Intermediate directions are also defined. Usually, a diagram called a compass rose, which shows the directions , is marked on the compass. When the compass is in use, the rose is aligned with the real directions in the frame of reference, so, for example, the "N" mark on the rose really points to the north.
