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 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 Colorline and some surface clutter.
Automatic Sensitivity
This unit has two sensitivity modes: Automatic and Manual. In auto-
matic you can adjust sensitivity up to 100 percent but the unit will
limit your minimum setting.
In manual mode, you have complete control over sensitivity, with the
ability to set it anywhere from zero to 100 percent.
