How to use a map and compass
To use a map and compass, lay the compass edge on the map from where you are to where you want to go, turn the dial until its lines match the map's north lines, then hold the compass flat and turn your body until the needle sits inside the outline arrow. Walk where the direction arrow points, picking landmarks along the line. Adjust for declination printed on the map.

How to do it
- Carry a paper map of the area and a baseplate compass, and check the declination printed on the map's margin.
- Find where you are by matching landmarks such as peaks, lakes, trail junctions or bends in a river.
- Place the compass edge on the map from your position to your destination, with the direction arrow pointing where you want to go.
- Turn the dial until the lines inside it run parallel to the map's north lines, with its north toward the top of the map.
- Apply the declination by turning the dial by the amount and direction the map gives.
- Hold the compass flat at your waist and turn your whole body until the red needle sits inside the outline arrow.
- Look up along the direction arrow, pick a landmark on that line, walk to it, and repeat.
- Check your position on the map at each trail junction or landmark.
Common mistakes
- Holding the compass near a car, phone or metal, which pulls the needle.
- Ignoring declination on a long walk.
- Walking while staring at the needle instead of at landmarks.
- Leaving the map in the pack until you are already lost.
