On the Water

Understanding the Chart

Whiteline

The Fishfinder 100 can help you to determine if the bottom is hard or

soft. When the sonar soundwaves are reflected back by the bottom, a hard

bottom will return a stronger signal than a soft bottom. The stronger

bottom return, the wider the bottom layer is displayed. The unit uses the

whiteline function to make this bottom layer information easier to

distinguish.

When viewing the display without Whiteline active, the bottom return

is black. While you can make some determination of the bottom type, the

black return makes this more difficult. With the whiteline active the

bottom return appears layered in shades of gray and black and makes

determining the bottom type easier and more reliable. Example 3 shows

the bottom return with and without the whiteline activated.

Whiteline can also help you to determine the

type of bottom structure that is displayed on

chart. By determining the hardness of the

structure you can make a better informed

decision on the type of structure.

Structure is hard,

probably a rock or stump

Structure is soft,

probably a mud pile
