10.2.2 Types of automatic sounder mode
Two types of automatic sounder modes are available: CRUISE and FISH.
CRUISE is for tracking the bottom, and FISH is for searching fish schools.
CRUISE uses a higher clutter rejection setting than FISH therefore it is not
recommended for fish detection – weak fish echoes may be erased by the clutter
suppression circuit.
