Thanks for all the help on the post guys!! I believe I will go with the TotalScan transducer on the trolling motor. Not overly worried about having side imaging on the trolling motor due to the fact that you have to be going a certain speed for it to work correctly. I'm used to hummingbird having an all in one transducer for my previous hummingbird 997. I am also under the impression that with the Gen3, the hub is not required to network between the two units due to wireless connection? Feel free to correct me if i am wrong.
