The
778c HD XD
allows you to choose 200/50 kHz, 200 kHz, or 50 kHz
(Default = 200/50 kHz).
• When set to
200/50 kHz
, the returns from both beams are blended by
starting with the 50 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 50 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
50 kHz
, the returns from the 50 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 50 kHz wide beam.
