trying to set optimal GAIN value for each situation. To avoid this it is advisable to
switch to MANUAL GAIN mode and fine tune the GAIN to a fixed setting.
6.13 In very deep waters even setting the Gain to its maximum
value I cannot see the bottom what shall I do?
Try decreasing the NOISE LEVEL. If still the bottom is not visible there is nothing
you can do, the bottom echo is simply too weak to be detected.
