F. Using a Compass
3 Adjust for declination.
If you have an adjustable compass – Move the Orienting Arrow to the right or left by
the declination number. When you align the magnetic needle with the Orienting
Arrow, the declination is accounted for.
If you do not have an adjustable compass – Mark the declination on your compass
with a piece of tape. Align the magnetic needle with the tape mark.
Adjust the Orienting Arrow to the left or right. For example:
For a declination of 0, no adjustment is necessary.
For a declination of 9 (9 degrees East), move the Orienting Arrow (or place a
tape mark) to the right 9 degrees.
For a declination of -9 (9 degrees West), move the Orienting Arrow (or place a
tape mark) to the left 9 degrees.
