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 Shaded Fish Symbols.

Dual beam sonar FishFinders represent targets detected in the 200 kHz narrow beam as Shaded Fish Symbols, and represent targets detected in the 83 kHz wide beam as Hollow Fish Symbols with their associated depths. The sonar return for the Hollow Fish Symbols will not be shown.

200 kHz, Narrow Beam

83 kHz, Wide Beam

Shaded Fish Symbols

Hollow Fish Symbols (Dual Beam units only)

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.

Transducer Cone and Fish Arches

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. (Off, On, Default = Off)
