Compass navigation is a method of finding direction using a compass, which is a simple tool that points toward magnetic north. The compass consists of a magnetized needle that aligns itself with the Earth's magnetic field, allowing users to determine their orientation. By knowing the cardinal directions—north, south, east, and west—navigators can chart a course and find their way in unfamiliar terrain. To use a compass effectively, one must hold it level and rotate the housing until the orienting arrow aligns with the magnetic needle. This process helps in reading the bearing, which indicates the direction to travel. Compass navigation is essential for outdoor activities like hiking, sailing, and orienteering, where GPS devices may not be reliable.
