Am I correct in saying that the only way to get 3kW CHIRP is with a TZT3 display and a DI-FFAMP?
I'm looking to add in the future a 3kW R599LM transducer.
Yes, you’re correct. If you're looking to add a High Power CHIRP transducer, 3KW R599LM, you will need the DI-FFAMP. The DI-FFAMP is only compatible to direct connect and use with a TZT3 display (TZT12F/TZT16F/TZT19F).
