Fish ID+™

Settings: Off, On; Default = On

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 ofrelative fish size.

DualBeam sonar models represent t argets d etected in the 20 0 kH z narro w beam as Shaded Fish Symbols and tar gets detected in the 83 kHz wide beam as Hollow Fish Symbols.

When Fish ID+™ is t urned o ff, t he Fishfin der shows o nly the r aw son ar returns on the display. These returns will often result in “arches“ forming on the display, indicating potential targets. D ue t o t he t ransducer b eam angle, the distance to a f ish decreas es 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.
