TVG: The fish schools of the same size are dis-
played in different color between in deep water
and in shallow water because of the feature of
the ultrasonic waves. TVG compensates for
propagation attenuation of the ultrasonic waves.
It does this by equalizing echo presentation so
that fish schools of the same size appear in the
same density in both shallow and deep waters.
The gain is adjusted automatically depending
on the depth. The gain is low at short distance
and getting back with increasing distance. High
provides the greatest degree of gain reduction
