How to use a Compass
- Orient a map using a compass - Place the map on a flat surface and line up the orienting lines of the compass with the grid lines on the map.
- Take a bearing - Take the straight edge of your compass and line the bottom of the ruler with your current position. Then line it up with your current position and the destination you are going. Rotate the bezel so that the orieting lines align with the map's grid line. You will now know which way you have to go using the compass.
- Difference between true North and Magnetic North
- Adjusting for declination: The differences between the two poles (North and Magnetic North) to find bearings is called 'angle of declination'.
