Si Enhance - Humminbird HELIX 5 SI GPS Operation Manual

SI Enhance allows you to adjust your Side Imaging View in four categories: Sensitivity, Contrast,
Sharpness, and Contour Mode.
Whether you're searching the Side Imaging data for fish or certain bottom contour, the most
effective settings will vary with the situation. The display will update as you adjust each category.
SI Enhance can also be used during Recording Playback (see Views: Snapshot and Recording
View).
• Sensitivity: Controls how much detail is shown on the display. When operating in very
clear water or greater depths, increased sensitivity shows weaker returns that may be of
interest. Decreasing the sensitivity eliminates the clutter from the display that
is sometimes present in murky or muddy water. (1 to 20, where Low = 1, High = 20,
Default = 10)
NOTE: The Sensitivity can be adjusted from the SI Enhance dialog box or the Side Imaging X-Press
Menu. The Sensitivity setting is provided here so that you can easily adjust the Side Imaging data with
the other settings. See Side Imaging X-Press Menu: SI Sensitivity for more information.
• Contrast: Accents the light and dark parts of the Side Imaging data to provide greater
definition. (1 to 20, Default = 10)
• Sharpness: Filters the view and sharpens the edges of the Side Imaging data. (Off, Low
(L), Medium (M), High (H), Default = Off)
• Contour Mode: Controls how the water column is displayed in the Side Imaging Views.
In the normal display with the Contour Mode 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. (Off, On; Default = Off)
NOTE: If both SI Range Lines and Contour Mode are turned on, the SI Range Lines will remain
on the display, but the individual range numbers are not available (see Sonar Menu Tab: SI
Range Lines).
