15.6.2 CHECK THE TREK COURSE CORRECT
• During trekking, the Watch can
keep your course correct. For
example, the correct trail starts
from point A and finishes at
point E as it is drawn on the
adjacent map.
• Mark the points (identifiable
landmarks) where the trail turns
its direction or the trail branches
its way, such as the point A, B,
C, D and E on the adjacent map.
• Find out the bearing directions of point B from point A (315°), point C
from point B (0°), point D from point C (225°), and then point E from
point D (315°).
• During the trekking, make sure that the heading direction is 315° from
point A to point B. Performing the similar checking in other sections of
the trail.
IMPORTANT:
If you are in doubt of the directions and positions of the trail, consult-
ing the park administration office before starting the trekking.
15.7 MAGNETIC DECLINATION
15.7.1 WHAT IS MAGNETIC DECLINATION
• The Magnetic North Pole which is slightly different from the True North
Pole.
• The Outdoor Sports Watch 2000, like most magnetic compass, points
to the Magnetic North Pole. On the contrary, everything measure from
a map is related to the True North Pole.
• The angular difference between Magnetic North Pole and True North
Pole is called 'magnetic declination'. Its amount (degrees and
minutes) and direction (easterly and westerly) depend on where you
are in the world.
• For serious compass user or who intends to perform accurate
navigation, compass must be adjusted for magnetic declination.
