Fish ID+™
Fish ID+™ uses advanced signal processing to interpret
sonar returns, and will display a Fish Symbol when very selective requirements are met.
When a fish is detected, a fish icon and its depth are displayed above the return that has
been classified as being a fish. Three different fish size icons represent the intensity of
the sonar return, and provide an indicator of relative fish size. Single beam sonar
FishFinders represent targets as orange Fish Symbols.
When Fish ID+™ is turned off, the FishFinder 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.
To turn Fish ID+™ on or off:
1. Highlight Fish ID+ on the Sonar main menu.
2. Use the LEFT or RIGHT 4-Way Cursor Control keys to turn the Fish ID+™ setting On or Off.
