FasTrack bar graph 37 Sonar chart display options (from left) split zoom (all models) and split frequency (SeaFinder 320DF only). Digital data sonar chart display option. You can customize how the Sonar Page pictures and other data are displayed in many ways. We'll discuss all of those features and options in Section 4, but to show you how easy the sonar unit is to operate, see the following 10-step quick reference that will cover most fish finding situations. The quick reference describes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory. Your unit automatically displays digital depth and surface water temperature in the corner of the screen. The auto settings will track the bottom, displaying it in the lower portion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water. As you're watching the sonar returns, you can change the display by: Zoom in to enlarge the chart for more detail: press ZIN. Press MENU|ENT and the Sensitivity Menu will appear on the left of your screen. Boosting sensitivity will show more information on your screen, which may cause clutter. Reducing sensitivity will filter out some information, but could omit important images. We recommend adjusting sensitivity until the background is lightly "peppered" -- that is, scattered dots appear, but individual objects (like fish arches or bottom structure) can be easily picked out of the background. Stop the boat and get your lure or bait into the water at the depth indicated on the sonar chart. Gauge the fish depth by visually comparing the fish arches with the depth scale on the right side of the screen, or get a more accurate measure with the Depth Cursor. If you are drifting at a very low speed or anchored, you are not moving fast enough for a fish to return the tell-tale fish arch signal. As you drift over a fish, or as a fish swims through the transducer's signal cone, the fish echo will appear as a straight line suspended between the surface and the bottom.
