indicator
The course pointer provides an
indication of drift (right or left)
according to the scale shown at the edge
of the compass ring. The scale refers
to the distance between dots on the
course deviation indicator. The course
line to your destination is based on your
original starting point.
Move back to the “course line to
destination” to compensate for deviation
and to get back on course. This is most
useful if you are navigating on water
or where there are no major obstacles
in your path. It also helps you avoid
hazards to either side of the course, such
as shoals or submerged rocks.

Calibrating the Compass
Calibrate the electronic compass
(Oregon 300, 400t, 400c, and 400i)
outdoors. Hold the Oregon level while
calibrating and using the compass. Do
not stand near objects that influence
magnetic fields, such as cars, buildings,
or overhead power lines.
Calibrate the compass after moving large
distances, experiencing temperature
changes greater than 20°F (11°C), or
changing the batteries.
