Find your starting (point A) and ending (point B) location on your map.
Place the rulered long edge of the compass base plate on your map between point A and point B. The directional arrow at the top of the base plate should be pointing towards point B.
Rotate the compass dial so that its north and south markings line up with the north and south grid lines on the map.
Adjust the compass dial to account for the declination of the area as listed on your map. For example, if your map lists the declination of the area as 3 degrees east, you would adjust the compass dial so that the north marking on it is three degrees east of the map's north grid line. Declination is the angle in degrees between magnetic north (the north the compass needle points to) and true north (the north indicated on the map).
Remove the compass from the map and place it in the palm of your hand. The directional arrow located at the top of the compass base plate should be facing towards the tips of your fingers.
Rotate your body until the red part of the compass needle is aligned with the north marking on the compass dial.
Walk in the direction of the directional arrow on the compass.
