How to Select a Display

Your fish finder has six display modes. These modes are single frequency, dual fre-
quency, marker zoom, bottom zoom, bottom lock, and A-scope.
7.2.1

Single Frequency Display

The single frequency display shows either the low-frequency or high-frequency picture
on all the screen. Select a frequency according to your purpose.
• A low frequency gives a wide detection area. Use the low frequency for general
search and to find bottom conditions.
• A high frequency gives better resolution. Use the high frequency to inspect a school
of fish.
How to select a single-frequency display
Push the RotoKey to show the soft controls. Use
the RotoKey to select [LF (Low Frequency)] or
[HF (High Frequency)].
Note: For the FCV-1150, this function is inopera-
tive when the FCV-1150's NavNet menu is set for
Gain/Mode. The message shown below appears.
Use the RotoKey to click the OK button.
