To turn Fish ID+™ on or off:

ID+™ setting On or Off. (Off, On, Default = Off)
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
Sensitivity is used in conjunction with Fish ID+™. Fish ID+™ must be On for
Fish Sensitivity to affect the ability of the 900 Series™ 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
Sensitivity setting. (Low = 1, High = 10, Default = 5)
