Sensitivity & Auto Sensitivity

The sensitivity controls the ability of the unit to pick up echoes. Sensi- tivity can be adjusted, because water conditions vary greatly. 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 this detail, but it can also clutter the screen with many undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Grayline and some surface clutter.
