Garmin Fishfinder 100 Blue Owner's Manual

NOTE: When the frequency is set to 'Dual,' the appearance

of the ﬁ sh symbols will change. Fish returns from the center

of the beam will be black, but the ﬁ sh returns from the edges

of the beam will be clear.

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. The degree of

gray-scale can be used to determine bottom hardness. See page 33 for more

details on this feature.

To change the Whiteline Setting:

1. Highlight the 'Chart' tab on the Setup Menu.

2. Highlight the 'Whiteline' selection ﬁ eld and press ENTER.

3. Choose 'On' or 'Off' and press ENTER to accept the selection.

Scroll Speed

You can adjust the speed that the chart scrolls from right to left by

using the 'Scroll Speed' selection ﬁ eld. If you are sitting still or the chart is

moving too fast, slowing the scroll rate can be beneﬁ cial.

To adjust the Scroll Speed:

1. Highlight the 'Chart' tab on the Setup Menu.

2. Highlight the 'Scroll Speed' selection ﬁ eld and press ENTER.

3. Choose 'Fast,' 'Medium,' 'Slow' or 'Pause,' then press ENTER to accept

the selection.
