Setting Up Sonar
Use the Sonar Setup screen to define and adjust settings universal to all sonar screens.
From the Home screen, select Sonar > Sonar Setup.
Scroll Speed—adjust the rate at which the sonar scrolls from right to left (Ultrascroll™, Fast, Medium, or Slow). If using a speed-capable transducer, select Auto to have the scroll speed automatically adjust to the water speed of your boat.
Surface Noise—show or hide the sonar returns near the surface of the water. Hide surface noise to help reduce clutter.
Depth Line—quickly reference a specific depth (Show or Hide). To set the depth of the reference line, select Show, and then press up or down on the Rocker.
A-Scope—display a vertical flasher along the right side of the
screen.
Data Bars—show or hide depth, water temperature, water speed (if your transducer is capable), battery voltage, cruising, navigation, and the compass tape (page 9).
Note: To display water temperature or water speed, the connected transducer must be capable of measuring water temperature, water speed, or both. Select Auto to display the values.
