Navman 4432 - Manual

1-2 How the FISH 4432/4433 works The FISH 4432/4433 has two parts: - the transducer attached to the hull - the display unit. The transducer generates an ultrasonic pulse (sound that is above the hearing range of the human ear), which travels down towards the bottom at a speed of about 4800 ft/sec (1...

Power On / Auto Power Press to turn the fishfinder on. If the fishfinder is wired for auto power, it turns on automatically whenever the boat ’s ignition is turned on. This ensures that the engine hours counter and optional fuel functions are activated. A title display appears briefly. This is follo...

Scroll speed Use this to set the scroll speed on the display. There is a choice of: Very Fast , Fast , Mediu m , Slow and Pause. The depth of the water also af fects the speed of the display. Faster scroll speeds combined with a slow boat speed (typically between 2 and 6 knots) shows the most fish d...

Press MENU once or more until the Setup menu is displayed, then select Calibrate : The fuel options can be calibrated only when the optional single or twin engine kit is installed on petrol/gasoline engines. Speed* Calibration may be required because dif ferent hull shapes have dif ferent flow chara...

Temperature The factor y settings should be suf ficiently accurate for normal usage. To calibrate the temperature readout, first measure the water temperature with a thermometer known to be accurate. Use the cursor keys to display the temperature readout box, then increase or decrease the value to m...

4-1 Interpreting the display The sonar displays do not show a fixed distance travelled by the boat; rather, they display a histor y, showing what has passed below the boat during a certain period of time. The histor y of the sonar signal displayed depends on the depth of the water and the scroll spe...

Shadows Shadows are created around areas where the ultrasonic beam cannot ‘see’. These areas include hollows on the bottom or beside rocks and ledges, where the strong echoes returned of f the rocks obscure the weak echoes of the fish and may also create a double bottom trace. See following for an e...

When to use 200 kHz The 200 kHz frequency is best for seeing deep bottoms, showing detail and reducing noise. When to use 83 kHz The 83 kHz frequency is has a wider beam –good for locating features that can be examined in detail at 200kHz. Auto frequency This shows 200kHz detail on screen, but uses ...

4-3 Fish detection and display Where to find fish Underwater features like reefs, wrecks and rocky outcrops attract fish. Use the 83/200 kHz frequency display to find these features, then look for fish by passing over the feature slowly several times using the Zoom display (see section 5-2 Sonar Zoo...

Unwanted signal Gain Threshold line 4-4 Gain Gain (sensitivity) controls the amount of detail displayed on the FISH 4432/4433.
