Enhancing the Down Imaging View
Sensitivity controls how much detail is shown on the view. 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. This menu can also be adjusted from the Down Imaging
X-Press Menu (DI Sensitivity).
Adjust the Contrast setting to accent the light and dark parts of the Down Imaging data to
provide greater definition. To intensify the strong returns, increase the contrast. To intensify
the weak returns, decrease the contrast.
Turn on sharpness and select a filter level to sharpen the edges of the Down Imaging data.
