(561, 570, and 570 DI only)
Settings: DualBeam PLUS™: 200/83 kHz, 200 kHz, 83 kHz;
Down Imaging™: 200 kHz, 455 kHz; Default = 200 kHz
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 (561, 570) allow you to choose 200/83 kHz,
200 kHz, or 83 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 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.
