Fish ID Sensitivity
Fish ID 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 ID Sensitivity is used in conjunction with Fish ID+
TM .
Fish ID+ TM must be On for Fish ID Sensitivity to affect the ability of the 300 Series TM
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)

Time Sonar (RTS®) Window for more information.)
To change the RTS® Window setting:
