SET DECLINATION
Magnetic declination or variation measures the angle between the Earth's magnetic north and true north. The declination value for any region can
be found on current geographical charts. By correcting for declination, you can achieve a more accurate compass reading.
NOTE: Magnetic north changes over time; so use only current geographical charts to obtain the declination value for any geographical region.
