NAVMAN Fishfinder User Manual
Operation
Introduction
The FISH400 and FISH440 use sonar
technology to display lake or seabed contours
and to detect fish. The system consists of an
LCD display unit and a depth transducer
positioned in the water. The model FISH440 is
also supplied with integrated boat speed and
water temperature sensors.
The LCD screen is menu driven for ease of use.
The automatic detection can locate and display
the position of fish with three different size fish
symbols. This feature can be disabled so that
the LCD will display only the raw electronic
signals. Experienced users can use this mode
to extract even more information about the water
and seabed conditions.
Note

temperature data (depth only in the
