the front end of the direction line shows your compass bearing,
and as long as the North needle is aligned between the slit
marks, the direction line points toward your destination. You
can also take a bearing by directing the compass towards the
destination and by reading the compass bearing from the side
window. This bearing can be memorized by turning the direc-
tion ring to that bearing.
- Obtaining a bearing from a map

your point of departure to your destination. If necessary, use a
ruler to connect the two points, and hold the compass against
the ruler. Turn the direction ring until the direction slit marks
point to the magnetic North on the map. When proceeding from
map to terrain, all you have to do is keep the North needle
between the slit marks while going from point of departure to
destination.
- Setting a given bearing or direction
