Approaching; Catching - Furuno FSV-35S Operator's Manual

Approaching

The sonar lets you view the movement of a school of fish continuously, thus you can
approach a school confident of a good catch.
While a flock of birds hovering over the sea surface is usually a good indication of the
presence of a school of fish, the sonar can better verify the size of a school of fish.
3.12.4

Catching

While the sonar operator monitors the
sonar for other schools of fish, the crew
can scatter bait and water to attract fish
to the boat.
