83 kHz Sensitivity 

(Advanced: Dual Beam PLUS

TM 

and QuadraBeam

TM 

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: QuadraBeam

TM

Only)

455 kHz Balance

adjusts the sensitivity of the 455kHz beam.  Increasing the

sensitivity will display additional weak returns and decreasing the sensitivity will
display fewer weak returns.  The 455kHz 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 455kHz 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)

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).

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])
