Altimeter Page - Garmin Astro 220 Owner's Manual

The course pointer indicates your course of travel from
your original location and the distance off course.
Move to the center line to get back on course. This is
most efficient 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.
