Sensitivity & Auto Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. A low
sensitivity level (from zero to 50 percent) excludes much of the bottom
information, fish signals, and other target information.
High sensitivity levels let you see all the available information, but can
also clutter the screen with undesired signals. Typically, the best
sensitivity level shows a good solid bottom signal with Grayline and some
surface clutter.
