Hi,
Yes, as far as I know that's possible. But I can't see the point in doing it since most things will be less good and efficiently displayed than with the standard transducer setting. The QuadraBeam transducer is a simpler transducer than the sideimaging transducers are. The only thing that might be better is the ability to indicate fish in the "sidebeams" with the QuadraBeam transducer. The algorithm for this probably doesn't work with a sideimaging transducer because of the very much narrower beam.
