Using a Compass
A compass is a small tool with a big job: it helps you make deliberate choices when the landscape looks unfamiliar, the weather changes, or your sense of direction starts to wobble. Using a compass isn’t about marching blindly toward an arrow. It’s about connecting the instrument to a map, checking what the terrain is telling you, and keeping your decisions calm and repeatable.
First, get to know the parts. A basic baseplate compass has a magnetic needle, a rotating bezel marked in degrees, direction-of-travel arrow, and orienting lines. The red end of the needle points toward magnetic north. Before taking a reading, hold the compass flat and away from anything that could interfere, such as a phone, car, metal buckle, or power line. Even a small magnetic disturbance can give you a misleading direction. Check that the needle moves freely and settles before relying on it.
Next, learn how to take a bearing from a map. Place the compass on the map with one long edge joining your current position to your destination, and point the direction-of-travel arrow toward the destination. Turn the bezel until its orienting lines run parallel with the map’s north-south grid lines, with the orienting arrow pointing north. Read the number where the direction-of-travel arrow meets the bezel. That number is your map bearing. Maps and compasses may use grid, true, or magnetic north, so check the map’s information and set or correct for local magnetic declination according to your compass instructions. Don’t guess: the difference can matter over distance.
To follow that bearing on the ground, hold the compass level in front of you. Turn your whole body until the red needle sits inside the orienting arrow—often remembered as “red in the shed.” The direction-of-travel arrow now points along your intended route. Choose a visible landmark in that direction, walk to it, then check again. This keeps you from staring at the compass while moving, drifting around obstacles, or gradually veering off course. In dense woods or poor visibility, use shorter legs and check your bearing more often.
A compass works best as part of a navigation routine, not as a substitute for one. Keep track of where you are on the map, compare the terrain with what you expect to see, and notice features such as ridgelines, streams, trails, and valleys. If the landscape doesn’t match the map, stop and reassess rather than pressing on. A bearing can guide you in the right direction, but it can’t tell you whether a cliff, river, or unsafe slope lies ahead. If you become uncertain, return to a known location if it is safe to do so, and communicate your plan before heading out whenever possible.
Practise close to home: pick a landmark, take a bearing, walk to it, then navigate back. Repeat with a map and a few different routes. The goal is not speed; it’s building a dependable habit. Using a compass alongside careful observation turns uncertainty into a series of manageable decisions—and that is a skill worth having whenever conditions start to change.
