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 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)
