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.
Selectinga 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)
