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.
