Humminbird 4089701 DI Enhance, Imaging Sensitivity, (or, DI Enhance, Increase the Imaging Sensitivity, ) controls how the sonar returns are displayed on the Down Imaging™ Views

Imaging Sensitivity

Settings: Auto, 1 to 20, where Low = 1, High = 20;

Default = 10

Imaging Sensitivity (or Down 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.
