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™ 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)
