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.

PP Filter
: The Ping-to-Ping filter will only show you the
echoes if they are still present after several consecutive pings
(2, 4 or 8). This function will provide you with a more stable
echo presentation, as spurious echoes will be suppressed.
