MFD12 and DFF3 Transducer frequency selection?


New member
Hi all,

Have been trying to change the frequency of my broadband transducer without luck.

If anyone can help, please advise how to change the transducer frequency on my current setup.

Head unit: MFD12

Sounder: DFF3

Transducer: CA82B-35R (selectable frequency range from 65-110 KHz)

Have been trying to change this but cannot find the option in any menu…
I can see this option on a 295 setup(mates) but not on my MFD12, thanks in advance for any guidance. :?
What model are you running as your second transducer?
Do you have the CA82B-35R connected to the LF or HF connection?
