Showing the A-Scope The A-Scope is a vertical flasher along the right side of the screen that shows instantaneously the range to targets along a scale. From the Home screen, select Sonar > Sonar Setup > A-Scope > on. Setting Pic Advance The picture advance setting allows the sonar picture to advance faster by drawing more than one column of data on the screen for each column of sounder data received. This is especially helpful when you are using the sounder in deep water, because the sonar signal takes longer to travel to the water bottom and back to the transducer. The 1/1 setting draws one column of information on the screen per sounder return. The 2/1 setting draws two columns of information on the screen per sounder return, and so on for the 4/1 and 8/1 settings. 1. From the Home screen, select Sonar > Sonar Setup > Pic. Advance. 2. Select a picture advance setting. Showing Overlay Numbers You must have a water-speed sensor or a speed-capable transducer to show water-speed information, and you must have a water-temperature sensor or a temperature-capable transducer to show water-temperature information. You can set water temperature, unit voltage, water speed (if your transducer is capable), and navigation information to appear automatically on the Sonar screens. The navigation information always includes GPS speed and GPS heading, and includes bearing and off-course information while navigating. 1.
