I have a helix 7 and I was wondering if anyone has tried hooking to the Terrova with 1-pilot & sonar 2. How is the picture & detail?

Don't know anything about the Helix but have had 4 different finders hooked to mine. The readout was just as good with it as the stock ducer. It should work just fine.

I have the Helix 5 with just the 2D and GPS on my Terrova. I have some issues with the sonar screen display. The DF work fine with the transducer that came with it, but the sonar display with the US2 is a faded one color screen. It worked OK when I first hooked it up so I think I have an issue with the TD on the Terrova.

The Built in ducer on MK trolling motors is a 2 d sonar ducer only....will not work with DI or SI.

Thanks, Guys- I only have the Helix 7 without DI or Si. on my TM. I have 2 more units with SI & DI on the hull of boat. I appreciate your comments.

FYI- The Sonar 2 works great on my Helix 7, I am more than happy with the set up. Thanks to everyone!
