Hello snips Im in the process of getting a new 32 built and I am having troubles on getting your new chirp dff1 with r509 or staying old school with r209 and dff3. I fish waters from 200ft to 3000ft. I could use some help on making a decision. either transducers will be glassed into a hull pocket. will the chirp work with a r509and preform well ? or is the 509 and dff3 a better choice ? the screens I would like to use are tz or nav 3d :sorry
