Each map has North on it and grid lines that also show North, East, South, West.
If you want to travel from A to B:
- Align the edge of your compass along the line that connects A and B.
- Turn the bearing so that it points toward North parallel to the grid lines. Name this angle
- Add magnetic variation if applicable.
- Hand your compass before you and turn your body for angle until the magnetic needle with N on the arrow is aligned with the arrow that is drawn in the bearing.
- There you go.
