colored bars, each bar 30 seconds in time. It is useful for estimating elapsed
time.

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.
