Adjusting The Color Intensity; Sonar Setup - Garmin GPSMAP 12x3 Owner's Manual

Adjusting the Color Intensity

You can adjust the intensity of colors and highlight areas of interest on the sonar screen by adjusting the color
gain for traditional transducers or the contrast for some transducers. This setting works best after you have
adjusted the level of detail shown on the screen using the gain or brightness settings.
If you want to highlight smaller fish targets or create a higher intensity display of a target, you can increase
the color gain or contrast setting. This causes a loss in the differentiation of the high intensity returns at the
bottom. If you want to reduce the intensity of the return, you can reduce the color gain or contrast.
