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.
DualBeam PLUS™ sonar models represent targets detected in the 200 kHz narrow beam as orange fish symbols, and represent targets detected in the 83 kHz wide beam as blue fish symbols.
