Nav aids are displayed on the
as colored circles. Most of these aids are
buoys, lights, lighthouses, and daybea-
cons, which typically are maintained by
the U.S. Coast Guard. Nav aids warn you of
hidden dangers, such as underwater
hazards, and to help you safely navigate
specific waterways and channels.
When you move the cursor onto a nav aid,
the 6000i displays a description in the info
bar at the bottom of the screen, along with
the distance and bearing from your vessel
to the nav aid.
Buoys
Buoys are the most common type of nav
aid found along the coast and on your
charts. The 6000i shows green and red
channel marker buoys as green and red
circles, respectively.
Approach buoys are shown as circles with
black on the upper half and white on the
lower half.
Sound buoys (featuring an audible signal,
such as a bell, gong, or whistle) are identi-
fied by a description in the info bar.
