Place your compass on the area map with the Base Plate edge connecting where you are with where you want to go.

Set the compass heading by turning the compass Dial until the “N” aligns with Magnetic North (MN) on the map.

Remove the compass from the map and hold it level in front of you with the Direction of Travel Arrow pointing straight ahead. Turn your body until the red end of the Needle is directly over the Orienting Arrow, pointing to the “N” on the dial. The Direction of Travel Arrow now points precisely to your destination. Look up, sight on a landmark and walk to it. Repeat this procedure until you reach your destination.
