Setup Menu/Chart
Whiteline
‘Whiteline’ controls how the unit displays information about the
bottom type (hard or soft). With the Whiteline ‘OFF’, the bottom return
will display as black and contain no information on bottom hardness. With
Whiteline ‘ON’, the bottom return will become gray scaled and can be used
to determine bottom hardness. See page 31 for more detail on this feature.
To Change the Whiteline Setting:
1. Highlight the ‘Chart’ tab on the Setup Menu.
2. Highlight the ‘Whiteline’ selection field and press ENTER.
3. Choose ‘ON’ or ‘OFF’ and press ENTER to accept the selection.
Scroll Speed
The speed that the chart scrolls from right to left can be adjusted using
the ‘Scroll Speed’ selection field. If you are sitting still, or the chart is
moving too fast slowing the scroll rate can be beneficial.
To Adjust the Scroll Speed:
1. Highlight the ‘Chart’ tab on the Setup Menu.
2. Highlight the ‘Scroll Speed’ selection field and press ENTER.
3. Choose ‘Fast’, ‘Medium’, ‘Slow’ or ‘Pause’, press ENTER to accept the
selection.

If you are using the Fishfinder 100 on the portable case battery power,
slowing the scroll rate will help to conserve your battery.
