Magnetic declination is the significance map is to the geographic north and south pole between radialdrawing， so the correct use of the compass positioning must be correcting declination on the map.

So the world is divided into 5 regions， each region manufacturing compass take "balancing pretreatment" to fit the area. Latitude isthe most common application in the northern hemisphere， have taken the counterweight to the guide end. Well-known manufacturers of the compass will which one applies to the 5 area specified in the specification. Balance of pre-processing by weight adjustment.
