Im considering putting a unit up front on my boat. I currently have a Helix 9 G1N and an newer Ulterra, with network cable between them.


I'm thinking of purchasing a better unit for the helm, and move my current Helix 9 up from to use the Ulterra's built in transducer. (I do already have the adapter cable I bought erroneously when I got the trolling motor- to hook a hummingbird directly to it)


If I bought a new Helix 10/12 mega, what issues might I run into? Would these units be networkable together? I.e, could my 9 show waypoints I made on the newer helix?

Are there better options I should be considering?


Thanks in advance!
