■How to read compass bearing

The compass bearing can be read from the compass.
Compass bearing reads the number written on the compass bezel.
When looking at the compass with the rubber line pointing in the direction of travel, the number indicated by the magnetic needle is the compass bearing in the direction of travel.

The figure below shows the compass as you move in various directions.
