Title: Navigating with a Compass and Topographic Map


1
Navigating with a Compass and Topographic Map

Begin by laying your laminated topographic map on
a flat, non-metallic surface that does not
interfere with your magnetic needle of your
compass.

13
Place your compass on the map so that the center
of the magnetic needle is directly over the
intersection of your line and the orienting line.
14
At the same time, position the compass so your
marker line and direction of travel line are over
the line drawn on map.
15
Also, spin the bezel dial so the orienting lines
are parallel to the orienting line(s) on the map.

TURN THE MAP (and compass) so that the north end
of the magnetic needle is inside the orientating
arrow of the compass.

Using that bearing, find an object in the
distance that is in that bearing. Walk to that
object.
24
When you reach this object, find another object
in the distance at that bearing. Walk to it.

Continue repeating this procedure until you reach
your destination.
