Magnetic Declination
The Magnetic sensor in the compass is attracted by the magnetism of the Earth
and therefore always points to the constantly shifting Magnetic North. There is
another “North Pole.” True North is static and located geographically about 800
miles north of the magnetic pole. Maps and directions usually are based on True
North. Magnetic declination is the angle between True North and Magnetic
North. The amount of
declination at any given point
depends on the location of
that point on the continent.
Where True and Magnetic
North are in the same
direction, the declination is zero.
At any point west of that line, your
compass needle will point east of True
North. This is called "Easterly
Declination." At any point east of that
zero line, your compass needle will
point west of True North. This is called
"Westerly Declination."
NOTE: The watch displays Westerly Declination as a negative number.
