A compass is a simple, yet essential tool for navigation. It consists of a magnetized needle that is suspended on a pivot point, allowing it to rotate and align with Earth's magnetic field. This helps you determine which direction is north, south, east, or west. Compasses come in various styles and sizes, from pocket-sized versions that you can take on the go, to larger military-grade compasses with additional features like rotating bezels and luminous markings. Whether you're hiking through the wilderness, sailing on the open water, or just trying to find your way around town, a compass is an indispensable tool that can help you stay on course.
