Select Beams
The instructions in this section are only applicable if the selected sonar source includes more than one beam.
The beams selected in this menu affect all units that are sharing the sonar source. For example, if you select the blended
83/200 kHz beams for one control head, and you select the single 83 kHz beam on another control head, the control head with the
single 83 kHz selection will receive blended information.
