Sonar Menu Tab
When
Fish ID+™ is turned off
, the Fishing System shows only the raw sonar
returns on the display. These returns will often result in “arches“ forming on the
display, indicating potential targets. Due to the transducer beam angle, the
distance to a fish decreases as the fish moves into the beam, and then
increases as it moves out again, creating a Fish Arch when this distance change
is shown on the display. Boat speed, chart speed, and the position of the fish
within the sonar beam greatly affect the shape of the arch.
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.
