Depth Line-adds a horizontal depth line across the screen that is used to measure the depth of underwater objects. The depth of the line appears in a box on the right side of the line. Press up or down on the ROCKER to move the line on the Sonar Page. Noise Reject-helps filter unwanted noise from the Sonar Page. The Noise Reject can be turned Off, set to Normal (automatically adjusts for optimum viewing) or to a fixed 1-100% setting. When setting the Noise Reject, remember that a higher noise rejection setting is less likely to show fish or structures. Resizing the Split Screen You can adjust the way the split screen is shown. This option is only available when a zoom scale other than No Zoom is selected. To resize the Sonar Page split screen: 1. From the Sonar Page split screen, press Menu. 2. Using the ROCKER, highlight Size Split, and press Enter. 3. Move the horizontal double-arrow left or right using the ROCKER until the vertical width line shows, then press Enter. 4. If you want to cancel this operation, press Quit or press Menu, highlight Stop Resizing, and press Enter. Setting up and Using Sonar > Using the Sonar Page Using the Pointer on the Sonar Page You can show the pointer (arrow) to reference sonar items and mark underwater waypoints. This makes it easier to find and use an object such as a stump for a future fishing location. When using this feature, the Sonar Page pauses. The depth continues to update while the screen pauses, but the unit does not show any new sonar data until the Sonar Page resumes scrolling. To mark an underwater waypoint: 1. From the Sonar Page, press Menu, highlight Show Pointer, and press Enter. 2. Use the ROCKER to move the pointer to the location you want to mark. Press Enter. The New Map Waypoint Page appears. 3. To change the name, symbol, or depth, highlight the appropriate field and press Enter. Make your changes, and press Enter when done. 4. When finished, highlight OK, and press Enter. 5. To return to the standard Sonar Page, press Quit; or press Menu, highlight Hide Pointer, and press Enter. GPSMAP 496 Owner's Manual 123
