Beam Select
(DualBeam PLUS™ and QuadraBeamTM Only)
Beam Select sets which sonar returns from the transducer will be displayed on the screen.
When set to 200/83 kHz, the returns from both beams are blended by starting with the 83 kHz wide beam return, dimming it, and then overlaying it with the 200 kHz narrow beam return. The darker 200 kHz narrow beam sonar returns will stand out from the paler 83 kHz narrow beam sonar returns. The Split Sonar View continues to display the sonar returns from each beam in their respective windows. The blended information is shown in the Sonar View, Sonar Zoom View and the Big Digits View. The RTS® Window in the Sonar View will only show the returns from the 200 kHz narrow beam.
When set to 200 kHz, only the returns from the 200 kHz narrow beam will be displayed in the Sonar View, the Sonar Zoom View and the Big Digits View. The Split Sonar View will continue to display returns from both beams in their respective windows. The RTS® Window in the Sonar View will display the returns from the 200 kHz narrow beam.
When set to 83 kHz, the returns from the 83 kHz wide beam will be displayed in the Sonar View, the Sonar Zoom View and the Big Digits View. The Split Sonar View will continue to display returns from both beams in their respective windows. The RTS® Window will display the returns from the 83 kHz wide beam.
NOTE: Beam Select does not affect the Side Beam View. The Side Beam View will continue to display sonar returns from the 200 kHz narrow beam in the upper frame and returns from the 455 kHz side beams in the two lower frames irrespective of the Beam Select setting.
To use Beam Select:
1.Highlight Beam Select on the Sonar main menu.
2.Use the LEFT or RIGHT
Fish ID+TM
Fish ID+TM 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 models represent targets as Shaded Fish Symbols.
DualBeam PLUS™ sonar models 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.
QuadraBeamTM sonar models 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. In addition, targets detected in the 455 kHz side beams are represented with Hollow Fish Symbols.

When Fish ID+TM 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.
To turn Fish ID+ on or off:
1.Highlight Fish ID+ on the Sonar main menu.
