Fish ID Sensitivity
Settings: Low = 1, High = 10; Default = 5
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.
