Adjust your compass for the declination of your area by the permanent method.
Take a bearing to the first site (a)— without disturbing the dial setting.
Place the compass on the map so that either side of the base plate intersects the
symbol for the chosen site (a). keep the edge of compass base plate on the symbol
and turn entire compass on the map until the compass orienting lines in the bot-
tom of the dial are parallel with the orienting lines on the map, and so that the
orienting arrow points upward on the map (North).
NOTE: Orienting arrow may be slightly off of North because of declination adjust-
ment.
Draw a line on the map along the edge of the compass, intersecting the symbol. You
are somewhere along this line. To establish your position along this line, you need
another bearing.
Take a bearing to the second site (b) and mark a line as you did with site (a). This line
will intersect the first line. Where the lines cross is your exact position.
