Compass History
People knew about magnet and how it affected iron 600 years before it was used for the first time as a compass. Even then it was not used for navigation but for geomancy. 900 years later it was used in astronomy and for orientation and for same purposes is used still.
Compass Facts
Compasses differ according to purpose, complexity, materials and some solutions that were used to solve some problems that could appear during their use. They also changed during the history, from the moment they were invented.
Compass Making
A simple as it is, there is a skill in how to use compass, especially when it is used with other tools and instruments, and knowledge in how it works. As compass was perfected, its use became more complex.

Instrument used for navigation and orientation
This article is about the direction finding instrument used in navigation. For other uses, see Compass (disambiguation).
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers.
Compasses often show angles in degrees: north corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearings which are commonly stated in degrees. If local variation between magnetic north and true north is known, then direction of magnetic north also gives direction of true north.
Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the ChineseHan dynasty (since c. 206 BC),[1][2] and later adopted for navigation by the Song dynasty Chinese during the 11th century.[3][4][5] The first usage of a compass recorded in Western Europe and the Islamic worl
