I think I understand your concept here...of separate left and right crystal piezoes...and also the idea to show the "DI views" of the concept left and right crystal data side by side in a split screen DI view orientation..

This would allow one to descern echoes from the left piezo separated from the echoes in the right piezo ....instead of the confusing blend DI view of all echoes in the present down-looking piezo...

This seems as it would classify the "new design" DI unit as a conventional SI unit (as verbiage dictated by separate left and right piezoes)...but with total coverage slice beams of 45°-800kHz/75°-455kHz....whereas...conventional present SI total coverage slice beams ofof 110°-800kHz/180°-455kHz...

And taking your software change idea of the separated left and right view...I think this would even be beneficial with the present DI from SI views in the conventional SI units....have the option of a split left and right piezo data view...instead of (or in addition to)...the present "blended" DI view from the echo data of both the left and right SI beams...
