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 Fishing System to identify
sonar returns as fish.
