4. Declination correction
The meridian lines on a map indicate the direction
toward true north while your compass needle indicates
the direction toward magnetic north. The angle
between these two directions is called magnetic
declination.
Before navigating you should check your local magnetic
declination from a trusted source, such as a recent map
or the NOAA website. If the magnetic declination is
more than a few degrees, you must compensate for it
when navigating.
1. Turn the compass over and extend housing.
2. Turn capsule until screw-head is visible.
3. Insert the metal key into the adjustment screw.
4. Turn the key until the declination indicator is the
correct number of degrees east or west of 0°.
5. Sight a bearing
A bearing is the angle between direction to north and
the direction to a target. This can be used for example
in communicating directions with others or when
finding your location.
1. Open the mirror and hold the compass at eye level
so that you can read the capsule from the reflection.
2. Align the target with the sighting notch or hole,
keeping the center line on the mirror in line with
the center of the capsule.
3. Hold the compass steady and turn the capsule until
the orienting arrow and needle are aligned.
NOTE: Compensate for declination. See section 5.
4. If the numerical bearing is needed, read it from the
bearing index.
6. Finding your location
You can sight two or more objects and use
triangulation to accurately determine where you are.
