Beam Select

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. 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.

To use Beam Select:

1.Highlight Beam Select on the Sonar main menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to select either the 200 kHz beam, the 83 kHz beam or the 200/83 kHz beam. (200/83 kHz, 200 kHz, 83 kHz, Default = 83 kHz)

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.

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 Shaded Fish Symbols.

200 kHz, Narrow Beam

83 kHz, Wide Beam Blue Fish Symbols

Orange Fish Symbols

(DualBeam PLUS™ Only)

When Fish ID+™ is turned off, the Matrix™ 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)
