4.1 Color Bar
The color bar shows the relation between echo intensity and echo color on the screen. The top
color (reddish brown) is the strongest color and the lower colors the weakest. The bar can be
used as a reference to estimate density of a fish school, fish species and hardness of the
bottom. The background color can be selected on the menu screen.
