Fish 4430/4431 Installation and Operation Manual

1 Introduction

Congratulations on choosing a NAVMAN fishfinder. For maximum benef it, please read this manual carefully before installation and use.

This manual describes the installation and operation procedures for the FISH 4430/4431.

The NAVMAN Fishf inder

The FISH 4430/4431 is an ultrasonic fishfinder with four levels of greyscale. It provides powerful software and a large, high-resolution screen with a zoom facility and a choice of fish symbols. As well as detecting fish, the FISH 4430/4431 measures the water depth, battery voltage, engine hours and water temperature.

The Fish 4431 also measures boat speed and has two distance logs ( Trip Log and Total Log).

An installed FISH 4430/4431 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, spreading out into a cone shape. When the pulse meets an object, such as a fish or the bottom, some of the pulse is reflected back up towards the boat and is received by the transducer. The depth of an object can be calculated by measuring the time between sending the pulse and receiving its echo. The NAVMAN FISH 4430/4431 will detect the bottom down to 600 feet (180 metres), depending on the clarity of the water and the type of transducer used.

The strength of an echo can vary for a number of reasons. Larger fish usually return stronger echoes, and so do fish in the middle of the cone, where the pulse is strongest. Reasons for weak echoes include the fish or object being in deep water, turbid water or in the edge of the cone where the pulse is weakest. Turbid water scatters the ultrasonic pulse and is difficult to ‘see’ through. Turbidity can be caused by air in the water (e.g. from another boat’s wake) or by mud in the water.

Important

It is vital to the performance of the fishfinder that the transducer is installed in the best location. Please follow the instructions in the Transducer Installation manual very carefully.

All of the NAVMAN 4000 Series fishfinders use proprietary SBN Technology for sonar processing to improve signal enhancement, bottom recognition and noise rejection. SBN Technology uses the latest in digital adaptive filter algorithms to enhance all returned signals. At the same time, SBN Technology uses active noise control to reject interference, which can of ten be mistaken by fishfinders for true returns. Using SBN Technology, the FISH 4430/4 431 analyses the reflections from each pulse, filters false returns, and displays what is in the water under the boat.

The distinctions between the four levels of shading help the user to better interpret what is in the water and what type of bottom is under the boat.

Assisting with navigation

The FISH 4430/4431 can be used to f ind fish, to locate features on the bottom such as reefs or wrecks, and to help recognise favourite fishing spots from the profile of the bottom. Use the NAVMAN fishfinder to assist navigation by following the depth contours marked on charts.

IMPORTANT NOTE ON USE. While any fishfinder can be used as an aid to navigation, accuracy can be inf luenced by many factors including the location of the transducer. It is the user’s responsibility to ensure that the FISH 4430/4431 is installed and used correc tly.

How to find fish

Underwater features like reefs, wrecks and ro cky outcrops at tract fish. Use the FISH 4430/4431 to find these features, then look for fish by passing over the feature slowly several times using the ZOOM screen (see section 3-4). Where there is a current, the fish will often be found downstream of the feature.

Fish 4430/4431 Installation and Operation Manual

For deep-sea fishing with the FISH 4430/4431, a rapid change in temperature may indicate the edge of a warm or cold current. The temperature difference can form a barrier, and the fish may not swim through this. Search for fish on either side of the barrier.

Cleaning and maintenance

The FISH 4430/4431 should be cleaned with a damp cloth or mild detergent. Avoid abrasive cleaners and petrol or other solvents. Always cover or remove a transom-mounted

transducer when repainting the hull. If painting over a through hull transducer with antifouling paint then use only one coat of paint. When repainting the transducer, remove previous coats of antifouling paint by sanding it lightly.

When not in use, the FISH 4430/4431 can either be removed from the installation bracket and stored in a safe, dry, cool place such as the NAVMAN carry bag, or left on the installation bracket and securely covered with the optional sun cover.

Alarms

The HISTORY screen does not show a fixed distance travelled by the boat; rather, it displays what has passed below the boat during a cer tain period of time. The actual display depends upon the boat speed and the depth of the water.

As the boat travels through shallow water, the echoes have less distance to travel between the objec ts and the boat. This means that the HISTORY screen display moves across the screen more quickly than when the boat is travelling in deep water. In deep water, the echoes take longer to travel between the objects and the boat, producing a display that moves across the screen more slowly.

Note 1: Different fish symbols can be selected (see section 4-3).

Note 2: The depth of bottom can be adjusted for keel offset (see section 4-7).

Selected depth range (0 to 150’)

Range

Range is the depth of water displayed ver tically. The NAVMAN fishfinder has two range modes, Auto Range and Manual Range:

· In Auto Range, the fishfinder adjusts the depth range automatically so that the bottom is always shown in the lower part of the screen. The use of Auto Range is recommended.

· In Manual Range, the fishfinder shows only a selected depth range. In areas of rapidly changing bottom depth, such as the sea floor around pinnacles, it can be useful to prevent the screen from rescaling to always show the bottom. If the bottom is deeper than the specified depth range, it will not be shown on the display screen.

To change the range mode, (see section 3-8).

Changing the Gain Mode

Gain (sensitivity) controls the amount of detail displayed on the screen. The fishfinder has two gain modes, Auto Gain and Manual Gain :

· In Auto Gain, the gain is automatically adjusted to compensate for water depth and clarity. The use of Auto Gain is strongly recommended when learning to use a fishfinder, or when travelling at speed.

· In Manual Gain, the user can adjust the gain to compensate for water depth and clarity. Manual settings range from 1 to 9. High settings may amplify normal background noise until it appears as random pixels on the screen. The ideal setting produces only a small number of random pixels. Normally the best results with a f ishfinder are obtained in Manual Gain but prac tice and experience are required to understand how to adjust the gain correctly.

To change between Auto Gain and Manual Gain, hold displayed briefly at the bottom of the screen.

When in Manual Gain the gain symbol shown at the top of the display, followed by the gain level. Press + to increase the gain level or press - to decrease the gain level.
