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.
