New Terrova with I pilot, what fish finder pairs best?

hey i apologize if there is a similar thread below, i scrolled through the first few pages and didn't see one that would answer my question...

so I bought the Terrova with i pilot installed already, used it all last year but would like to replace my fish finder with one that is compatible to the motor to actually use its capabilities.... i read that only hummingbird will link with it then also read other ones will too..

looking for suggestions that wont break the bank, any info would be greatly appreciated

cheers!

I thought it was only hummingbird. This is a universal transducer so don't thing you are going to get any SC or DS. I hooked up my 785 to my ulterra this year, it works great but don't have to many functions. Maybe I just haven't figured it out yet. For depth and fishfinder it is great and has helped me jigging for whities, and eyes. Does cause interference on my lowrance I have mounted at the back of boat.
