Paraluman

Ing paraluman (compass o mariner's compass king Ingles) metung yang kasangkapan king pamaglayag (navigational instrument) bang abalu ing nangan o direksiun king Yatu. Atin yang pánurung (pointer) magnetized o mebatubalani a timawang tumulid king magnetic field ning Yatu, at maragul yang saup king pamaglayag. Keraklan, makamarka la king lupa ning paraluman deng mamuntukan a nangan (cardinal directions o cardinal points) ning pangulu, mauli, aslagan ampong albugan. Maragul ing paniulung a miliari king kalakal king kadayatmalatan uli ning paraluman, uling meging mas ligtas ampong mas malagua ing pamaglakbe. Maliari yang gamitan ing paraluman ba yang carculan ing heading o direksiun/nangan a pupuntalan. Nung gamitan yang kayabe ya ing metung a sextant, maliari neng ibie ing latitude, at nung maki marine chronometer, ing longitude. Uli na niti, minasensu ing pamaglayag, dapot ngening bayu-bayu pamu, miyalilan ne kareng makabayung kasangkapan, anti ing gyrocompass ampo ing Global Positioning System (GPS).

 Beware: The Brief History of the Bezard compass (1852 – 1971) on the Knowfuture site is a hoax. There is no such village in France. A Jewish family Bézard never existed. The Bezard compass was created by Johann von Bézard, an Austrian Colonel of French Huguenot origin and built by the LUFFT company in Germany whose factory was in Stuttgart. The BASF chemical company is situated on the river Rhine in Ludwigshafen. The whole story is beautiful but unfortunately untrue. Reliable information can be found on the following private sites:
