Cancel Navigation
(only when Navigating)

Imaging Sensitivity
Settings: Auto, 1 to 20, where Low = 1, High = 20;
Default = 10
Imaging Sensitivity controls how the sonar returns are displayed on the
Down Imaging™ Views.
Increase the Imaging Sensitivity to reveal weaker returns that may be of
interest, especially in very clear water or greater depths. A high imaging
sensitivity setting shows more sonar returns from small baitfish and suspended
debris in the water; however if the sensitivity is adjusted too high, the display
may become too cluttered.
Decrease the Imaging Sensitivity to eliminate the clutter from the display that
is sometimes present in murky or muddy water. If the sensitivity is adjusted too
low, the display may not show many sonar returns that could be fish.
DI Enhance
Settings: Press the RIGHT Cursor key.
DI Enhance allows you to adjust your Down Imaging™ View in the following
categories: Sensitivity, Contrast, and Sharpness.
Whether you’re searching the Down 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. DI Enhance can also be used during
Recording Playback (see Views: Snapshot and Recording View).
