As a symbol [ edit ] A computer drawn compass, used to symbolize precise designing of applications. Distances can be measured on a map using compasses with two spikes, also called a dividing compass (or just "dividers"). The hinge is set in such a way that the distance between the spikes on the map represents a certain distance in reality, and by measuring how many times the compasses fit between two points on the map the distance between those points can be calculated. To put it simply, the compass is a tool which points out directions, such as North, South, East and West. These are also known as the cardinal directions.

Historians think China may have been the first civilization to develop a magnetic compass that could be used for navigation. Chinese scientists may have developed navigational compasses as early as the 11th or 12th century. Western Europeans soon followed at the end of the 12th century. This activity will put their creative and directional skills to use by making their own Compass Rose. This is the star-like figure that is found on compasses and points out the different directions. wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. To create this article, 36 people, some anonymous, worked to edit and improve it over time. The school compasses (models 550 50, 550 55, 550 60, 559 WP 00) in our product range are specifically designed for younger children. These extra-safe precision compasses have a blunt safety needle to prevent injury.You can use a steel or iron nail, horseshoe, crowbar, or other household item if you don't have a magnet. The pencil lead draws the circle on a particular paper or material. Alternatively, an ink nib or attachment with a technical pen may be used. The better quality compass, made of metal, has its piece of pencil lead specially sharpened to a "chisel edge" shape, rather than to a point.

At STAEDTLER, our product range includes a large selection of high-quality compasses. Our models are particularly sturdy, providing the ideal basis for creating precise drawings at school and in professional applications. We offer products that meet various requirements, from solid metal to sturdy plastic/metal designs. Our compasses are also available in compact sets with practical accessories. Close to the poles the particles are able to reach the atmosphere. This causes the air to light up in a display called the Aurorae . A solar compass uses the sun as a navigational tool. The most common method is to use a compass card and the angle of the shadow of the sun to indicate direction.The handle, a small knurled rod above the hinge, is usually about half an inch long. Users can grip it between their pointer finger and thumb. The screw through the hinge holds the two legs in position. The hinge can be adjusted, depending on desired stiffness; the tighter the hinge-screw, the more accurate the compass's performance. The better quality compass, made of plated metal, is able to be finely adjusted via a small, serrated wheel usually set between the legs (see the "using a compass" animation shown above) and it has a (dangerously powerful) spring encompassing the hinge. This sort of compass is often known as a "pair of Spring-Bow Compasses". A beam compass (or trammel) offers longer reach and easier adjustment than an ordinary compass. This beam compass is made largely of stainless steel and has a modern look. Very early compasses were made of a magnetized needle attached to a piece of wood or cork that floated freely in a dish of water. As the needle would settle, the marked end would point toward magnetic north.

To start with you need to know where you are on the map (point A) and where you want to go to (point B). The Carpenter's Manifesto, Jeffrey Ehrlich & Marc Mannheimer, Holt, Rhinehart & Winston, pg. 64, 1977 OS Maps Never explore without one! Stay safe, and stay active with Britain’s most accurate outdoor maps. If you’re unsure about using a compass the best thing to do is get the map of an area you know really well, where you wouldn’t usually need a map to get around. Take yourself off for a walk, using the map and a compass to navigate your way as you reach each turning. This way you shouldn’t get lost and you can compare that the direction you think you should be travelling in matches what the compass is telling you! Many compasses have a smaller scale inside the compass housing to make this easier, or use the outer scale. Most compasses only show a marker for every 2 degrees.Our precision geometry compasses are ideal for geometry class at school as well as for technical drawing. These sturdy plastic and metal or solid metal models include a spindle guide consisting of a spring-bow head and centre wheel. On some models, the lead and needle legs are hinged. We also offer practical sets that are specifically aimed at children starting school. Depending on the model, these consist of: Case with hinged lid containing 1 precision compass with lead part, universal adapter and spares box During the 12th century, Europeans created the compass rose. It enabled the creation of the eight principal winds, which includes the four cardinal directions (North, South, East, West) plus the new intercardinal directions; North-East, South-East, South-West, North-West.
