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 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 the
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, the Sonar Zoom View, the 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, the Sonar Zoom View, the 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.
