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. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish
ID Sensitivity setting. (Low = 1, High = 10, Default = 5)
Real Time Sonar (RTS®) Window

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 = Narrow)
