Auto range In auto range, the system automatically displays the whole range from the water surface to the bottom. Auto is the preferred setting for fish finding. Select the range option and then the auto option in the menu. Frequencies Two frequencies are supported. 800 kHz provides the sharpest image without sacrificing range. While 455 kHz can be used in deeper waters, or for expanded range capabilities. Contrast Determines the brightness ratio between light and dark areas of the screen. Ú Note: We recommend that you use the auto contrast option. Palettes Used for selecting the image's color palette. Advanced options Surface clarity Wave action, boat wakes and temperature inversions can cause onscreen clutter near the surface.
