Shellback is correct: the PMax 170 uses the same 200/83kHz DualBeam transducer that the 587ci HD unit uses.

I think that strmwalker was thinking about the DI version of this unit (587ci HD DI) and if this actually is a 587ci HD DI model than he would be correct.


So many models it’s hard to keep everything straight! Thankfully I have the voices in my head to help me…
