Application to Bonito and Tuna Fishing

Tracking of bonito and tuna presents a special challenge to the

sonar operator: He must try to keep them within the sonar beam,

a formidable task considering their high speed and penchant for

leaping and diving. The CSH-23F/24F, however, with its wide

vertical scanning beam, makes this task easier.

Searching

Neither the naked eye nor binoculars can continually track fish

schools which make lightning quick runs between the surface

and midwater. A sonar, however, provides a continuous view of

several hundred meters of sea area around the boat, both at the

surface and below it.
