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.
