I am running hummingbirds a gen 1 on bow gen 2 on console..i have them hooked directly to battery and not the trolling motor battery either. I also have added ground wire to skeg along with a round thing from hb...lol can't think of what it's called. I have a motorguide x5 trolling motor which I like. I still get interference on both units while using trolling motor. Question I have is if I switched to a minnkota would that solve the problem or is it just the nature of humminbirds?....thanks for any input as I'm at my wits end...
