The FISH 4432/4433 is a high quality, dual-
frequency sonar fishfinder that is supplied
with a dual-frequency transducer. It uses a 16
level greyscale FSTN display for easy daylight
viewing that can be dimmed for night fishing.
The bracket mounting option also allows
the fishfinder to be tilted and swivelled for
optimum viewing.

The FISH 4432/4433 can detect the bottom to
a depth of 750 feet (230 metres) depending
on the clarity of the water, the ultrasonic
frequency chosen and the type of transducer
used.

IMPORTANT NOTE ON USE. While any
fishfinder can be used as an aid to navigation,
accuracy can be limited by many factors,
including the location of the transducer. It is
the user’s responsibility to ensure the Navman
fishfinder is installed and used correctly.
