Auto Gain - Garmin Fishfinder 160C Owner's Manual

Whiteline
The Whiteline setting controls how the unit displays information
about the bottom type (hard or soft). With Whiteline off, the bottom
return displays as a solid color. With Whiteline on, the strongest
area of bottom return becomes white and can be used to determine
bottom hardness. A hard bottom returns a stronger signal and
displays a thicker bottom layer. A soft bottom returns a weaker
signal and displays a thinner bottom layer.

Auto Gain

The Auto Gain setting controls the sensitivity of
the receiver when in the gain option is set to Auto.
Auto Gain has three settings; High, Medium,

the FF160C more aggressive when adjusting gain
automatically. High auto gain may lead to excessive clutter on the
screen.
