I would guess that xducer is indeed the Tribeam that came standard with the Wide Optic ...

If your question is whether a different model head unit would work on that xducer - I would say partially (the 200kHz piezo in the Tribeam is the same as the piezo in other HB units with 200kHz 2d capability) ...

I would try to select "Dual Beam" in the transducer options Menu of any other HB head unit connected ... and select 200kHz only in the "Beam Frequency" menu to shut off any other transmit frequency ...
