What is a Prismatic Compass?
One of the specialty types of magnetic compasses, the prismatic compass makes use of a small capsule that is filled with oil and a magnetized dial. This combination is augmented with a battery powered illumination component that helps to provide one of the most accurate compass readings of any type. Sometimes referred to as an optical compass, the pinpoint accuracy of the device helps to make prismatic compasses ideal for a number of applications where lighting is in limited supply. As with all types of compasses, the prismatic compass makes it easy to isolate a direction from any point on the planet. The pointer within the device will align with the pull of the natural magnetic field of the earth, ensuring that the compass will make it easy to accurately determine the basic directions of north, south, east, and west. It is not unusual for the magnetic compass to be used as part of an overall navigation process, with such devices as chronometers and sextants used to further refine the
