I bought a Helix 7 to pair to my new Fortrex 80 with built in transducer. I thought I was getting the Fortrex with the Mega SI, but found out it's not on the market yet, I have just the Mega DI.
I still have the transom mount transducer that is not recommended for the trolling motor, as it needs the extra shielding. Any reason I can't send the transom transducer back and trade for trolling motor transducer?
Love my Helix 7. Picture is so clear!
