A compass is a navigational instrument for determining direction relative to the Earth's magnetic poles. It consists of a magnetized pointer (usually marked on the North end) free to align itself with Earth's magnetic field. The compass greatly improved the safety and efficiency of travel, especially ocean travel. A compass can be used to calculate heading, used with a sextant to calculate latitude, and with a marine chronometer to calculate longitude. It thus provides a much improved navigational capability that has only been recently supplanted by modern devices such as the Global Positioning System (GPS).
These high quality reproduction Compasses are replicas of the original Compasses used by mariners over the ages to guide and navigate them over the Oceans of the world. The are made of finest Brass. The NauticaL compass make an exciting nautical gift and executive presents to anyone who loves the sea. The term "compasss" denotes a wide range of instruments for drawing, measurement, and proportional calculation, to track routes on sea-charts. Compasses with curved points, called gunner's compasses, was used to measure mouths of cannons, cannon balls. Sophisticated surveying compasses that combined a magnetic compass, a windrose, and optical sights are used for surveying and for drawing topographic maps. |
