Beam
The Beam setting allows the selection of a Narrow Beam or Wide
Beam for the transducer. A narrow beam provides higher detail
structure returns of a smaller bottom area. The wide beam shows a
larger fish return area with poorer detail of non-bottom structure.
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 , and Low . Increasing the
Auto Gain setting makes the Fishfinder 160C more
aggressive when adjusting gain automatically.
High auto gain may lead to excessive clutter on the
screen.
