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 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 additional detail).

RTS® Window (Wide)

RTS® Window (Narrow)

RTS® Window (Off)

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 [Default = Off for Matrix 10])

83 kHz Sensitivity

(Advanced: DualBeam PLUS™and QuadraBeamTM Only)

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)

455 kHz Balance

(Advanced: QuadraBeamTM Only)

455 kHz Balance adjusts the sensitivity of the 455 kHz beam. Increasing the sensitivity will display additional weak returns and decreasing the sensitivity will display fewer weak returns. The 455 kHz Balance menu choice is available when User Mode is set to Advanced (see Setup Menu Tab: User Mode).

To change the 455 kHz Balance setting:

1.Make sure you are in Advanced User Mode, then highlight 455 kHz Balance on the Sonar Main Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 455 kHz Balance. (-10 to +10, Default = 0)
