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 4430/4431. The NAVMAN Fishfinder 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.
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.
Power off To turn the fishfinder off, hold . A countdown box appears. Continue to hold for three seconds until the fishfinder turns off. Note: If the unit is wired for Auto Power (see section 5-4) the fishfinder can only be turned off when the boat’s ignition is turned off. Language selection To check which language is currently selected, press to display the MAIN MENU. Follow these steps to change the language: 1. Power off the unit. 2. While the unit is off, hold down the key. 3.
SONAR screen (see section 3-5) Displays the strength and depth of the echoes returned from each ultrasonic pulse. The depth range is displayed in the lower right corner. This screen is a powerful aid, ideal for showing the bottom hardness and the fish species. This screen can also be used to adjust the display shading on the HISTORY and ZOOM screens. NAVIGATE screen (see section 3-6) Prominently displays the water depth as a digital readout. The corresponding bottom trace is also shown.
3-2 HISTORY screen operation Range Select MAIN MENU - HISTORY to display the HISTORY screen. The HISTORY screen displays the most recent echoes on the right of the screen and the oldest echoes on the left. These eventually disappear off the screen. 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.
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 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 following picture shows the HISTORY screen with the fish symbols turned off: Single fish The strength of the returned echo varies with several factors, such as: · The size of the fish, school of fish or other object. · The depth of the fish or object. · The location of the fish or object. The area covered by the ultrasonic beam is approximately cone-shaped and echoes are strongest in the middle. · The clarity of water. Particles or air in the water reduce the strength of the returned echo.
Shadows Shadows are areas where the ultrasonic beam cannot ‘see’. These include hollows on the bottom or beside rocks and ledges where the strong echo returned off the rock obscures the weaker echo of the fish. When looking for small objects including fish, users should consider that there are places where fishfinders cannot ‘see’. Shadow - where objects are hidden in the bottom echo. These fish will be hidden in the bottom echo. NAVMAN fishfinders display the most recent events on the right of the screen.
Stationary boat 1 minute ago Now Time When a boat is stationary, all bottom echoes will come from the same small area of bottom. This will produce a flat bottom trace on the screen. The appearance of the HISTORY and ZOOM screens can be changed to suit individual preferences. Note: Times indicated are for illustration only. 3-4 ZOOM screen Select MAIN MENU - ZOOM to display the ZOOM screen. The ZOOM screen is split into two parts.
3-5 SONAR screen Select MAIN MENU - SONAR to display the SONAR screen. This is a powerful feature and with some experience, this screen can be used to identify both the type of bottom and the fish species. On the Sonar Echo section on the right side, the strength of an echo at a particular depth is shown by a horizontal line at that depth. A strong echo produces a long line, whereas a weak echo produces a short line. Below the echoes the screen shows the Shading Bar.
Manual Gain When Manual Gain is selected, increasing the gain setting will result in more detail being shown on the fishfinder display. Decreasing the gain will reduce detail being shown. See ‘Changing the Gain Mode’ in section 3-2 for more information on changing Gain settings. Gain setting These echoes will be shown in grey on the Fish History section. These strong echoes will be shown in black on the Fish History section.
3-7 DATA screen Select MAIN MENU - DATA to display the DATA screen: Temperature Temperature Graph Battery Log Engine hours Speed Enabled alarms Depth A graph displays the surface water temperature for the last 40 minutes and is updated every 30 seconds. The current water temperature is displayed above the graph and is updated every second. The temperature can be displayed in °F (Fahrenheit) or °C (Celsius).
4 SETUP menu Select MAIN MENU - SETUP to display the SETUP menu: Use the SETUP menu to customize settings to suit the boat and individual preferences, as follows: · Specify the trigger settings for the alarms (see section 4-1). · Choose the units for depth, temperature, speed and fuel (see section 4-2). · Turn the key beep on or off. · Choose the fish symbol (see section 4-3). · Choose the contrast level (see section 4-4).
4-1 ALARMS menu Select MAIN MENU - SETUP - ALARMS to display the available alarms. Press or to highlight an option. Alarms can be enabled to automatically detect certain conditions, such as the water being too shallow. Trigger settings can be defined to suit the boat and individual preferences. The beeper cycle is different for some alarms.
Flashing Light and/or External Beeper If a secondary alarm indicator is required, a flashing light and/or external beeper can be installed. These can be positioned anywhere suitable on the boat. For installation advice see section 5-4. Enabling Alarms and Changing Trigger Values Press or to highlight an alarm, then press to select it. To enable or disable an Alarm, press to switch between ON and OFF. To set the trigger value for an Alarm, press or to increase or decrease the trigger value.
4-3 FISH SYMBOL Select MAIN MENU - SETUP - FISH SYMBOL to display the fish symbol options for the screen displays. There are three options. Press · to select: OFF · · Echoes which are not recognised as fish are displayed as dots on the screen. Displays any echoes returned that match the profile of a fish as a fish symbol in one of three sizes as above. The depth of the fish is shown to the left of the symbol. Echoes which are not recognised as fish are displayed as dots on the screen.
4-6 LOG menu (FISH 4431 ONLY) Select MAIN MENU - SETUP - LOG to display the available options. Press or to highlight an option: LOG Selects which log is displayed on the DATA screen, TOTAL or TRIP. ZERO TRIP LOG Resetting the trip log will return the trip log value to zero. The trip log is retained in the fishfinder memory so it retains the distance value if the fishfinder is switched off during a trip. Therefore, the trip log needs to be reset manually each time the user wishes to log a trip.
Use Keel Offset either when the transducer is located below the water surface but a display of total water depth is required, or when depth of water below the boat’s keel is required. Transducer Water surface Positive value Depth of transducer Negative value Note: Boat illustrated uses a through hull transducer Enter positive values to display depth as measured from a point above the transducer (e.g. water surface). Enter negative values to display depth as measured from a point below the transducer (e.
4-9 Resetting to Factory Defaults Important: This option resets all of the following settings and resets them to the manufacturer’s default settings. Speed and distance are related. For example, if knots are chosen as the speed units, then distance is always measured in nautical miles. To reset the fishfinder to the manufacturer’s default settings, power off the fishfinder. Then hold and power on while holding it. The message “RESET TO FACTORY DEFAULTS?” appears. Press to select YES or NO.
