pete g:
if i was going to hook up one transducer would there be any polarity concerns?

Zero999:
It depends, but my crystal ball has gone a little cloudy.

woofy:
Plastic transducer, no problem.
Metal transducer, depends:
Check the case to the pins with a multimeter. If none are connected,  no problem.
If one pin is connected, make sure it is grounded if the circuit allows or at least isolated.

pete g:
hi, thanks for responses. how would you hook up two or more in parallel?
