FISH 4100 Installation and Operation Manual NAVMAN

1 Introduction

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

This manual describes the installation and operation procedures for the FISH 4100 and FISH 4150. The manual generally refers to both products as the NAVMAN fishfinder. The product name is used only when describing features specific to that particular fishfinder.

The NAVMAN Fishfinder

The FISH 4100 is an ultrasonic fishfinder. 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 4100 measures the water depth, battery voltage and engine hours.

The FISH 4150 also measures the water temperature, the boat speed and has two distance logs (Trip Log and T otal Log).

An installed NAVMAN fishfinder has two p arts:

- 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 fishfinder 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, as 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 or 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 new proprietary SBN Technology for sonar processing to improve signal enhancement, bottom recognition and noise rejection. SBN T echnology 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 often be mistaken by fishfinders for true returns. Using SBN Technology, the NAVMAN fishfinder 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 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 profile of the bottom. Use the NAVMAN fishfinder to assist navigation by following the depth contours marked on charts.

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

How to find fish

Underwater features like reefs, wrecks and rocky outcrops attract fish. Use the NAVMAN fishfinder 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.

For deep-sea fishing with the FISH 4150, a rapid change in temperature may indicate the edge of a warm or cold current. The temperature difference can form a barrier which the fish may not swim through. Search for fish on either side of the barrier.

Cleaning and maintenance

The NAVMAN fishfinder 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 NAVMAN fishfinder can either be removed from the installation bracket and stored in a safe, dry, cool place such as the NA VMAN carry bag, or left on the installation bracket and securely covered. An optional sun cover, that also prevents key depressions when in place, is available from NAVMAN dealers.

Alarms automatically re-enable

The TOO SHALLOW, TOO DEEP and LOW BATTERY alarms automatically re-enable when the value moves outside the alarm trigger setting.

The TEMP VALUE alarm automatically re-enables when the temperature is more than 0.45°F (0.25°C) above or below the alarm trigger setting.

The TEMP RATE alarm automatically re-enables when the rate of temperature change falls below the trigger setting by more than 0.2°F (0.1°C) per minute.

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 4-4).

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

Range

Range is the depth of water displayed vertically. 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.

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

Changing the Gain Mode

Gain (sensitivity) controls the amount of detail displayed on the screen. The NAVMAN 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 fishfinder are obtained in Manual Gain but practice and experience are required to understand how to adjust the gain correctly .

T o change between Auto Gain and Manual Gain, hold

or -. The Gain mode will be displayed briefly at

is shown

Fish detection and display

The fish symbol option can be customized, or switched off altogether so that the echoes are not converted to fish symbols on the screen. Section 4-4 explains how to do this. The differences between Fish symbol on and off are:

Fish Symbol ON

Using NAVMAN’s SBN sonar technology the fishfinder analyses all return signals and eliminates most false signals and clutter so that remaining targets are most likely fish. Depending on the strength of the remaining signals, they are displayed as either small, medium or large fish symbols

- with or without depth. Whilst the SBN processing is very sophisticated it is not foolproof and there will be times when the unit will not be able to differentiate between large air bubbles, rubbish containing air, fishing floats etc. and genuine fish returns.

Fish Symbol OFF

For experienced users this will always provide the best information as every sonar return signal is displayed, whether it is surface clutter, a thermocline or a fish.

3-3 HISTORY screen interpretation

Fish Arches

In ideal conditions and with Fish Symbols turned OFF , a fish passing through the cone-shaped ultrasonic pulse is displayed on the screen as a fish arch:

As the fish enters the weak edge of the sonar cone it generates a weak return signal that turns on the first pixel on the fishfinder screen. As the boat moves closer to the fish the distance between the transducer and the fish reduces and the return signal is displayed at progressively shallower depths, producing the start of an arch. When the fish is directly beneath the transducer and in the middle of the beam then the

NAVMAN FISH 4100 Installation and Operation Manual

returned signal is even stronger so the arch becomes thicker. As the fish passes out of the cone the reverse happens with a progressively weaker and deeper return.

In reality there are many reasons why fish arches can’t be seen. For example:

· Poor transducer installation - please refer to the Transducer Inst allation Guide.

· If the boat is anchored then fish will tend to show on the display as horizontal lines as they swim into and out of the transducer sonar beam. Slow speeds in deeper water give best fish arch returns.

· Range is important. It will be much easier to see fish arches when using NAVMAN’ s split screen zoom mode to concentrate on a particular section of water rather than just displaying everything from the surface to the bottom. Zooming increases screen resolution and is necessary for good fish arches.

· It is almost impossible to get fish arches in shallow water as the transducer sonar beam is very narrow near the surface and fish do not stay within the beam long enough to display an arch. Several fish in shallow water tend to display as randomly stacked blocks of pixels.
