Hello all. I am looking at replacing the units on the boat I just bought. I have a MK Terrova with iPilot (dont think its Link) but not sure. I am wanting to replace the front Graph and probably eventually the rear one so I can link them. I have been looking at the Humminbird Helix and Solix series. To get DI/SI upfront, the built in transducer from the terrova would not be enough correct? I would have to run a new transducer under the motor I assume if I understand it all correctly. Lastly, what combo do you recommend I go with upfront and back at the consol so they link nicely to share waypoints etc. The 360 technology is pretty nice but it is not a must for me. I would love to not have to run a new transducer under the trolling motor if at all possible.
