GPS Applications
Using the Course Pointer or the Bearing
Pointer
The bearing pointer indicates the direction to your
destination, and the course pointer indicates your
relationship to a course line leading to the destination.
The bearing pointer points to the destination, regardless
of the direction you are moving. If the bearing pointer
is pointing in your direction of travel, you are traveling
directly toward your destination. If the bearing pointer
points any other direction, turn toward that direction until
the bearing pointer is pointing ahead.

Bearing Pointer

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.
