Beam Select
Settings: Various, see below.
Beam Select sets which sonar returns from the transducer will be displayed on the screen. The
available beam frequencies are determined by your Humminbird model.
DualBeam PLUS models (HELIX SONAR GPS) allow you to choose 200/83 kHz, 200 kHz, or 83
kHz (Default = 200 kHz).
• 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 wide 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 and Circular Flasher 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, Sonar Zoom View, Big Digits View, and the Circular Flasher 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, Sonar Zoom View, Big Digits View, and the Circular Flasher 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.
Down Imaging models (HELIX DI GPS) allow you to choose
200 kHz or 455 kHz for conical sonar coverage in the
traditional sonar views.
• When set to 200 kHz, only the returns from the 200 kHz
(28°) beam will be displayed.
• When set to 455 kHz, only the returns from the 455 kHz
(16°) narrow beam will be displayed.
