Learn to read a compass properly ,and we'll always know which way to go.
1.
Hold the base plate compass flat in front of your chest so that the compass needle floats freely and points to magnetic north. (The only thing a compass needle can do is point to magnetic north.)

2.
Rotate the entire compass housing until the needle sits within the orienting arrow stenciled onto the base of the compass housing. (Usually the orienting arrow is red.) The zero degree mark on the compass housing and the north end of the needle should be aligned - they now point to magnetic north.

3.
Keep the orienting arrow and the compass needle pointing north. Twist the base plate until the direction-of-travel line points exactly at the distant landmark you wish to move toward. Double-check to make sure everything is still properly aligned.

4.
Note the exact number of degrees marked on the compass dial where the direction-of-travel line intersects the compass dial. That number of degrees is the direction to the distant landmark.
