Side Imaging Sonar
Sensitivity
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 Side Imaging X-Press
Menu (SI Sensitivity).
Contrast
Adjust the Contrast setting to accent the light and dark parts of the Side Imaging data to
provide greater definition. To intensify the strong returns, increase the contrast. To intensify
the weak returns, decrease the contrast.
Sharpness Turn on sharpness and select a filter level to sharpen the edges of the Side Imaging data.
Contour Mode
Contour Mode controls how the water column is displayed in the Side Imaging Views. When
Contour Mode is turned off, the water column is displayed on the view. The location of a target
on the display is based on the slant range to the target.
When Contour Mode is turned on, the bottom is graphed at a constant point on the display,
regardless of changes in depth. The Side Imaging beams are divided by a vertical line. The
water column is removed from the view, which allows the display to show targets at their
linear horizontal distance. The location of a target may be easier to interpret when the water
column is removed.
