Fish ID Sensitivity
Fish ID Sensitivity adjusts the threshold of the
Fish ID+™ 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 ID Sensitivity is used in conjunction with Fish ID+™. Fish ID+™ must be On for
Fish ID Sensitivity to affect the ability of the Fishing System to identify sonar returns
as fish.
To change the Fish ID Sensitivity setting:
1. Highlight Fish ID Sensitivity on the Sonar main menu.
2. Press the LEFT or RIGHT Cursor keys to change the Fish ID Sensitivity
setting. (Low = 1, High = 10, Default = 5)
Real Time Sonar (RTS™) Window
RTS Window™ sets the RTS Window™ to either

transducer beam. See What’s on the Sonar Display for more information.
To change the RTS Window™ setting:
1. Highlight RTS Window on the Sonar main menu.
2. Press the LEFT or RIGHT Cursor keys to change the RTS Window™
setting. (Wide, Narrow, Off, Default = Narrow)
