Fish ID Sensitivity. Humminbird 500

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 Fishfinder 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)
