How to Select a Display

Your fish finder has six display modes. These modes are single frequency, dual fre-
quency, bottom zoom, bottom lock, A-scope, and bottom discrimination.
7.3.1

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
