Down Imaging® Beam Width controls the width of the beam (side to side) for
the Down Imaging® View and sets the amount of information shown on the
display.
To see only the data directly under your boat, select Narrow. Medium reveals
more information, while Wide displays the maximum information available from
the Down Imaging® beam width.
Ice Fishing Mode controls how information is displayed in the Circular Flasher
View. When Ice Fishing Mode is off, the Circular Flasher View displays Real
Time Sonar (RTS™) data in a traditional flasher format.
When Ice Fishing Mode is on, the Circular Flasher View displays the data in
flasher format with additional features including Zoom and Depth Cursor. Also,
the fishfinder's sensitivity settings are adjusted automatically to accommodate
ice fishing conditions. These settings will apply to the other Sonar Views until
you turn off the Ice Fishing Mode. See Views: Circular Flasher View for more
information.
