i have a question to ask for a man? that's new into fishfinders

[olduckhunter]

he has 2 hummingbirds. one is a 521 and one is a 535 i believe. he wants to know if the transducers will interchange from one to the other. i never got past the flasher stage of finders so i didn't know what to tell him.

[olduckhunter]

no one have an answer for the man? hummingbird greg? anyone? seems like a simple question.

Be patient oldduckhunter...

Greg is the authority on these series of units and which parts are interchangeable...

Greg will probably check in Monday....(he always quips that his wife keeps him busy with honeydo's on weekends....)

You may want to check the model number there olduckhunter as we have not made a model 521, but as long as there is no “DI” or “SI” in the model name the transducers should exchange.

[olduckhunter]

i was wrong i think he said the other was a 561. i'll ask him if there is a di or si. if not thank you for your answer.

[Humminbird_Greg]

561 and 535 use the same transducer. Completely interchangeable as long as that was not a 561 DI model.

[olduckhunter]

thanks a lot.
