Evidence suggests that the magnetic compass was invented in China between 221 and 206 B.C. The earliest compasses were not used for navigation, but for fortune-telling. Chinese compasses became navigational orienteering devices between 1040 and 1044 A.D. and were used as maritime navigational devices by 1117 A.D.
A thumb compass is a type of compass commonly used in orienteering, a sport in which map reading and terrain association are paramount. Consequently, most thumb compasses have minimal or no degree markings at all, and are normally used only to orient the map to magnetic north.he magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since about 206 BC), and later adopted for navigation by the Song Dynasty Chinese during the 11th century. The use of a compass is recorded in Western Europe and in Persia around the early 13th century.
