Sensitivity
Sensitivity controls how much detail is shown on the display and will adjust the sensitivity of
all sonar frequencies. Decrease the sensitivity to eliminate the clutter from the display that
is sometimes present in murky or muddy water. When operating in very clear water or greater
depths, increase the sensitivity to see weaker returns that may be of interest.
Contrast
Adjust the Contrast setting to accent the light and dark parts of the Mosaic data to provide
greater definition.
