DFF1 or internal TZT2BB

[Wdeertz]

I’m upgrading my NN3D to a TZT2BB. With my NN3D I had a DFF1 fish finder. The TZT2BB has a built in fish finder. Looking at the specs I think the internal and DFF1 have similar specs. Am I better to connect my triducer (525STID-MSD) directly to the TZT2BB or the DFF1?

The DFF1 has more circuits and while they both would work about the same, I would recommend keeping the DFF1 in place.

Johnny, ok thanks, will continue to use my DFF1 in my upgrade.
