Here's a pic of some interference that I am getting from my 80 lb Terrova. You can see the haze created with the motor on, then back to a good image with it off, then back to the hazy interference with it on. I will be working on this issue by installing the filtered power cord and running the power cord directly to the cranking battery. I have mounted a 788 DI unit on the Terrova and it is pretty cool to watch both units working simultaneaously. Any other suggestions on this set up?
