Item
Fish Alarm Sets the fish alarm sensitivity; that is,
Level the minimum echo strength which will
trigger the fish alarms.
Transmission Turns TX power on/off.
TVG TVG (Time Varied Gain) compensates
(HF,LF) 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. In addition, it reduces
surface noise. Note that if the TVG
level is set too high short range
echoes may not be displayed.
