Furuno CSH-23F/24F manual Tracking, Approaching

Tracking

If you are visually tracking a fish school which characteristi- cally leaps and dives regularly, or a school with a flock of birds hovering over it, the school will scatter once the vessel ap- proaches, thus you will lose sight of the school. The CSH-23F/ 24F provides continuous pictures of underwater conditions, so you can always know where a fish school is. For tracking the schools which leap and dive often the vertical scanning mode is especially effective.

Approaching

•The sonar lets you view fish school movement continuously, thus you can approach a school confident of a good catch.

•While a flock of birds hovering over the sea surface is usu- ally a good indication of the presence of a fish school, the sonar can better verify fish school size.
