Contrast and Overlay options will only be active on the Adjust menu with DownScan Overlay enabled. Sensitivity Controls the level of detail shown on the display. Too much detail will clutter the screen. If Sensitivity is set too low, desired echoes may not be displayed. Colorline Separates strong sonar echoes from weak sonar echoes.
