Sonar Settings – Main Menu System
Less frequently-adjusted menus are grouped into the Main Menu System. Press the MENU key twice to access the
Main Menu System.
Fish ID+
TM
uses advanced signal processing to interpret sonar returns and display a Fish Symbol when very selective
requirements are met. A number above the fish icon indicates the depth of the fish. Three different fish size icons
show the intensity of the sonar return, and provide an indicator of relative fish size. When Fish ID+ is turned off, the
Matrix shows only the unprocessed sonar returns on the display. These returns will often result in "arches" forming
on the display, indicating potential targets.
Fish Sensitivity
adjusts the thresholds of the fish detection algorithms, thus enhancing your unit’s ability to
identify sonar returns as fish icons. Selecting a higher setting allows smaller returns to be displayed as fish icons
and will increase the number of fish icons that appear on the display. This is useful for identifying smaller fish
species or baitfish. Selecting a lower setting displays fewer fish icons by eliminating many small sonar returns.
This is helpful when seeking larger species of fish.
Bottom View
selects the method to display bottom and structure on the display.
WhiteLine®
highlights the strongest sonar returns from the bottom
to make a distinctive outline of the bottom contour, structure and fish.
Structure ID®
presents the graphical representation of the bottom and
structure sonar returns using only grayscale to indicate the signal strength.
Bottom Black
displays all pixels below the bottom contour as black,
regardless of signal strength.
RTS Window
turns the RTS window on or off in the Sonar View.

Fish ID Alarm
