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.
Alarm Settings - Main Menu Alarm Tab
Various audible alarms can be triggered in the Matrix unit based on these menu settings. When an alarm is triggered,
it can be silenced by pressing the EXIT key.
Depth Alarm sounds when the digital depth becomes equal or less than the menu setting.
Fish ID Alarm sounds when the Fish ID+ feature displays fish symbols that correspond to the menu setting.
Battery Alarm sounds when the input battery voltage is equal to or less than the menu setting.
Alarm Tone selects the pitch of the alarm sound to improve audibility. As the menu is adjusted a brief tone will be
produced so that you can select the tone that you can hear best.
