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 (1158c) and Side Imaging® models (1198c SI) 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 and the 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 83 kHz, the returns from the 83 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 83 kHz wide beam.
Down Imaging™ models (1158c 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.
Xtreme Depth models (1158c 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.
