I'm getting a wagon wheel effect on my 360. Ive only had it a few months and haven't been able to really dial it in. Theres no oil leaking out of the unit so I'll assume its from interference. I have two Helix 10 SI Gen 1 units with the bow unit I am directly connected to. Do I need to turn the sonar off on the Helix 10 at the bow that its directly connected to or turn the console unit sonar off?
