: This setting controls the amplification of the received
echoes.
•
Pulse form
: The standard pulse form is
FM Auto
. If you
experience a lot of reverberation from the bottom, decrease
the pulse length. In good water conditions while searching for
scattered fish, you may well use setting
CW Long
.
•
TX Power
: This button switches the transmission power on
or off.
•
Frequency
: On the SH40 you can alter the sonar’s transmission
frequency. This is very useful if you have other vessels in the
vicinity. Remember that lower frequencies will increase the
range of your sonar, but also give you a wider beam.
•
TVG
: Time Varied Gain. This function will automatically
adjust the gain in the sonar to compensate for geometric
spread and absorption.
•
RCG
: Reverberation Controlled Gain. This function will
automatically remove unwanted reverberation from the
bottom or from the sea surface. It may however also remove
scattered fish.
