11.6 Calibrate the Compass

See fig. 36.
The Magnetic North Pole is different from the North
Pole on your map. All magnetic compasses, point to
the Magnetic North, but a map relates to Geographic
(Map) North. The angular difference between the
two North poles is called declination. Depending
upon where you are on the planet, you will usually
need to adjust the Compass for declination. Most
topographic maps include a small arrow to show
Magnetic North and declination information. You can
also acquire this information from:
• USA – USGS at www.store.usgs.gov
• Canada – Centre for Topographic
Information http://maps.nrcan.gc.ca
