The
Down Imaging™ models (858c HD DI,
958c HD DI)
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 (25°) beam
will be displayed.
• When set to
455 kHz
, only the
returns from the 455 kHz (16°)
narrow beam will be displayed.
The
Xtreme Depth models
(
858c HD XD, 958c HD XD)
allow 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 and Sonar Zoom 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 and the Sonar Zoom 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 and the Sonar Zoom 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.
