How far does True North deviate from Magnetic North? — 1 Comment

  1. For anyone who still uses a compass rather than a GPS for hiking or other outdoor activities, the 1:50,000 surveyor-general maps of South Africa, as well as hiking maps for specific locations (such as the Drakensberg) derived from them, the magnetic declination is printed on the map itself. Usually it’s given as two arrows, one pointing magnetic north, the other true, so that a compass can be calibrated by adjusting the degree dial accordingly.
