FISH 4432/4433 Installation and Operation Manual5

1 Introduction

Congratulations on choosing a Navman fish-finder. For maximum benefit, please read this manual carefully before installation and use.

This manual describes how to install and set up the FISH 4432/4433 and the associated dual-frequency transom transducer. (If a through hull transducer is used, refer to the Installation Instructions supplied with that transducer.)

This manual also explains how to operate the FISH 4432/4433 effectively and provides troubleshooting information and performance tips.

1-1 Benefits of the FISH 4432/4433

The FISH 4432/4 433 is a high quality, dualfrequency sonar fishf inder 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 dual frequenc y capability enables the FISH 4432/4433 to operate and display:

• At a high frequency of 200 kHz.

• At a low frequency of 83 kHz.

• Both frequencies side-by-side on a split display.

• Both frequencies combined together into a single display.

This capability, combined with a variable power output of up to 250 watts, ensures that the FISH 4432/4433 operates effectively in shallow and deep water.

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.

The Navman fishfinder can be used to find fish, to locate features on the bottom such as reefs or wrecks and to help recognize favourite fishing spots from the bottom profile.

The Navman fishfinder can also assist with navigation by providing depth information to

It is vital to the performance of the fishf inder that the transducer is installed in the best location. Please follow the installation instructions very carefully.

help identify the depth contours marked on charts. The FISH 4 432/4433 is par ticularly suited to work with the TRACKER 5430/5380.

The two instruments can be connected together using either NavBus or NMEA, so they can share data. (only applies to FISH 4433)

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

With the optional fuel kit, the FISH 4433 also becomes a sophisticated and easy-to- use fuel computer.

All of the Navman 4000 Series f ishfinders use new proprietary SBN-II Technology for sonar processing to improve Signal enhancement, Bottom recognition and Noise rejection.

SBN-II Technology uses digital adaptive filter algorithms to enhance all returned signals. At the same time, SBN-II Technology uses active noise control to reject interference, which can often be mistaken by fishf inders for true returns.

Using SBN-II Technology, the Navman fishf inder analyses the reflections from each pulse, filters false returns and displays what is in the water under the boat. See section 4-1 Interpreting the display, for more information.

1-2 How the FISH 4432/4433 works

The FISH 4432/4 433 has two par ts:

- 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 (1463 m/sec), spreading out into a cone shape.

When the pulse meets an objec t, such as a fish or the bottom, it is partly reflected back up towards the boat as an echo. The depth of the object or bot tom is calculated by the FISH 4432/4433 by measuring the time taken between sending a pulse and receiving the echo. When an echo has been returned, the next pulse is sent.

The FISH 4432/4 433 converts each echo into an electronic signal, displayed as a vertical

Scroll speed

Use this to set the scroll speed on the display. There is a choice of: Very Fast, Fast, Medium, 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 detail. Medium or Slow scroll speeds result in sonar information being displayed over a longer period, but with less detail. See Section 4-1 Interpreting the display, for more information.

Fish symbols

These appear only in the main sonar displays. Fish symbols can be shown in three ways:

• As a fish symbol (Sy m bol).

• As a fish symbol with the depth

(Sym bol+ dept h). The depth is shown beside the fish symbol.

• As a depth (Depth). The depth is shown above where the fish was detected

• Switched off (Off) so that echoes are not converted to f ish symbols but are displayed directly.

Warnin g

Navman fuel kits are only suitable for petrol/ gasoline engines. Fuel consumption can change drasticall y depending upon the boat loading and the sea conditions. Always carry adequate f uel for the journey, plus a reserve.

FISH 4432/4433 Installation and Operation Manual 12

Tan k ful l

Select Tank full each time the fuel tank(s) are completely refilled. When asked Are you sure? select Yes. Otherwise, the reading on the Fuel display (see section 5-6 Fuel Display) and the Low Fuel Alarm (see section 3 -5 Setup > Alarms) are meaningless.

Set remaining

Before doing a partial refill of the tank or removing fuel manually from the tank (for example, by siphoning it off):

1. No te the Remaining reading on the Fuel display.

2. Note how much fuel is added or removed.

3. Calculate how much fuel is now in the tank.

4. Select Set remaining and update the reading.

NAVMAN

It is essential to do this whenever some fuel is added or removed. Otherwise, the reading on the Fuel display (see section 5-6 Fuel Display) and the Low Fuel Alarm (see section 3-5 Setup > Alarms) are meaningless.

Clear used

Select Clear used to set Use d (the amount of fuel used) to zero. Do this to start measuring the amount of fuel used over a certain time or distance. When asked A re you sure? select Yes.

Tank size

Enter the capacity of the fuel tank.

Flow filter

Most engines do not draw fuel from the tank at a steady rate. To give a stable fuel flow reading, the fishfinder calculates the flow value(s) by taking several measurements and averaging them. Use the Flow filter to set the period over which the fuel flow is averaged.

The Flow filter can be set from 0 to 30 seconds. Use the lowest value which gives a stable flow. Usually a value of 5 to 10 seconds will give a satisfactory result for two-stroke carburettor engines. Fuel injec ted or four-stroke engines may require a larger value.

3-4 Setup > Logs

Press MENU one or more times until the Setup menu is displayed, then selec t Logs:

This setting affects the Fuel flow and Fuel economy reading on the Fuel display (see section 5-6 Fuel display) but it does not affec t the Fuel used reading.
