Fish Sensitivity
Fish Sensitivity adjusts the threshold of the Fish ID+
TM
detection
algorithms. Selecting a higher setting allows weaker returns to be displayed as fish. This is useful for
identifying smaller fish species or baitfish. Selecting a lower setting displays fewer fish from weak
sonar returns. This is helpful when seeking larger species of fish. Fish Sensitivity is used in conjunction
with Fish ID+
TM
. Fish ID+
TM
must be On for Fish Sensitivity to affect the ability of the Matrix Fishing
System to identify sonar returns as fish.
To change the Fish Sensitivity setting:
1. Highlight Fish Sensitivity on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish Sensitivity setting.
(Low = 1, High = 10, Default = 5)
Real Time Sonar (RTS®) Window
RTS® Window sets the RTS® Window to either Wide or Narrow, or
turns it off in the Sonar View. The RTS® Window always updates at the fastest rate possible and
only displays returns that are within the transducer beam. (See Real Time Sonar (RTS®) Window for
more information.)
To change the RTS® Window setting:
1. Highlight RTS Window on the Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the RTS® Window setting.
(Wide, Narrow, Off, Default = Wide)
83 kHz Sensitivity
(Advanced)
83 kHz Sensitivity changes the sensitivity of the 83 kHz beam. Increasing the 83 kHz Sensitivity
will display additional weak returns and decreasing the 83 kHz Sensitivity will display fewer weak
returns. The 83 kHz Sensitivity menu choice is only available when User Mode is set to Advanced
(see Setup Menu Tab: User Mode).
To set the 83 kHz Sensitivity:
1. Make sure you are in Advanced User Mode, then highlight 83 kHz Sensitivity on the Sonar
main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to set the 83 kHz Sensitivity. (-10 to +10,
Default = 0)
