[. . . ] Several fish in shallow water tend to display as randomly stacked blocks of pixels. Wave motion may result in distorted fish arches · 4-4 Gain Gain (sensitivity) controls the amount of detail displayed on the FISH 4430/4433. Understanding how to set suitable Gain settings is important for optimum performance. The Navman fishfinder has three gain modes, Cruising, Fishing and Manual. · Cruising Mode Use this mode to show only the bottom and large fish. Manual Mode The gain can be adjusted by the user to compensate for water depth and clarity. Note: The Gain mode automatically changes to Manual Gain if the gain or threshold settings are adjusted by the user. · Obtaining the best results To obtain the best detection capability for both fish and bottom we recommend the use of the Sonar A-Scope display: 1. Adjust the gain until the threshold line is just to the right of the unwanted noise. · High Gain settings may amplify the normal background noise until it appears as random pixels. Changing between Cruising, Fishing and Manual To change between Cruising, Fishing and Manual 1. Use the or cursor keys to highlight mode option, then use the cursor key then select desired option from list. Gain Threshold line Unwanted signal Adjusting Gain and Threshold settings The gain settings and the threshold settings can be adjusted independently for each frequency (83kHz and 200 kHz). Use the or cursor keys to highlight the desired setting, then use the cursor key to change it. Gain line FISH 4430/4433 Installation and Operation Manual NAVMAN 22 4-5 Range Range is the vertical depth displayed on the FISH 4430/4433. The Navman fishfinder has two range modes, Auto Range and Manual Range: · Zoom Range and Zoom Offset On the Sonar Zoom and Sonar Bottom displays, a vertical bar is shown on the far right of the display. For 100% zoom, use `full-screen zoom' display. The split display shows the sonar history on the right side and the zoom section on the left. The zoom bar on the far right shows the area that is magnified in the zoom section. See section 4-5 Range, for information about adjusting the Zoom Range and Zoom Offset. To change items, press MENU until the Options menu is shown. Data header Data header is explained in section 5-1 Sonar display. 25 NAVMAN FISH 4430/4433 Installation and Operation Manual 5-3 Sonar Bottom display To show the Sonar Bottom display, press DISP and select Sonar Tab, select Sonar Bottom and press ENT. This shows a split display, with the sonar history on the right side and the zoom section on the left. The bottom signal is shown as a flat trace in the centre of the zoom section. Showing the bottom as a flat trace can make it easy to compare the echo strengths shown in the bottom signals. This can help to identify the type of bottom and objects close to the bottom. It cannot indicate the zoom offset as this changes for each sounding displayed on the display. See section 4-5 Range, for information about adjusting the Zoom Range and Zoom Offset. Bottom lock and Split ratio are explained in section 5-2 Sonar Zoom display. 5-4 Sonar 83/200 display To show the Sonar 83/200 display, press DISP and select Sonar Tab, select Sonar 83/200 and press ENT.
