The RGC (Reverberation Controlled Gain) regulates the receiver
gain individual for each of the 64 receiving beams. As shown in
the menu, the RCG function has four settings. In WEAK and
MEDIUM selection, signals with small variations, like propeller
noise, surface and bottom reverberations will be removed, while
signals with fast variations, like target echoes or bottom echoes
will not be removed. In STRONG, a special filter removes the
bottom, while echoes on the bottom will be presented. Note that
scattered fish can be perceived as reverberation, so therefore the
RCGshouldbeusedwithcareifscatteredschoolsaretobe
detected.
