School compass
A compass has a rotating cover with a marking device, a limb (scale), a magnetic pointer, a sighting device (scale and compass), a calculation indicator (with 0-360° graduations) and a brake.
Compass surveying is not used in places which contain iron core, power lines etc which usually attracts magnets due to their natural properties and electromagnetic properties respectively.
Compass surveying is done by using traversing. A traverse is formed by connecting the points in the plot by means of a series of straight lines.
