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 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. Press the LEFT or RIGHT Cursor keys to change the Fish ID Sensitivity
setting. (Low = 1, High = 10, Default = 5)
