12.2 Setting declination value
To ensure correct compass readings, set an accurate declination value.
Paper maps point to true north. Compasses, however, point to magnetic
north – a region above the Earth where the Earth’s magnetic fields pull.
Because magnetic North and true North are not at the same location, you
must set the declination on your compass. The angle in between magnetic
and true north is your declination.
The declination value appears on most maps. The location of magnetic north
changes yearly, so the most accurate and up-to-date declination value can
be obtained from the internet (for example www.magnetic-
declination.com).
