If you know your current location on the map and want to travel to another mapped location:

  • Lay out the map on a flat surface and remove any metal objects from the area.
  • Place the flat edge of the compass (the side parallel to the direction-of-travel arrow) along the line between the two points. Be sure the direction-of-travel arrow points toward your destination.
  • Orient the map to north.
  • Without moving the compass, rotate the azimuth ring until the orienting arrow (indicated by N) and the orienting lines point northward on the map, as indicated by the map's north arrow or vertical lines.
  • Turn the map and compass together until the magnetic needle lines up with the orienting arrow.
  • Correct for east or west declination.
    • Rotate the azimuth ring left or right using the direction and the number of degrees given on the map.
    • Do not rotate the compass itself. It's okay if the magnetic needle does not line up with the orienting arrow.
  • Find where the degree marking around the azimuth ring lines up with the direction-of-travel arrow. That's the bearing to your destination.

Using a Compass To Travel Along a Known Bearing

  • Hold the compass level, and rotate the azimuth ring until the specified bearing (such as 240°) lines up with the direction-of-travel arrow.
  • Turn the compass, not the azimuth ring, until the orienting arrow lines up with the north end (usually red) of the magnetic needle.
  • Follow the direction-of-travel arrow toward your destination.
  • Periodically, recheck your bearing. Also, recheck your location on a map.
