Sonar Colors and Bottom View
As the boat moves, the unit charts the
changes in depth on the display to create
a profile of the
Bottom Contour
. The
Sonar View displays the sonar return
intensity with different colors.
Strong returns
often result from rocky or
hard bottoms (compacted sediment,
rocks, fallen trees), while
weaker returns
often result from soft bottoms (sand,
mud), vegetation, and small fish.
The colors used to represent high,
medium, to low intensity returns are
determined by the palette you choose in
the
Sonar Colors
menu option. See
Sonar
Menu Tab
to set the Sonar Colors.
