GPS Applications
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.

Course Pointer
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.
