Boss.... good idea. One transducer is enough. Btw.... I can't really say Semper Fi..... cause I am not a Marine. Just an old retired Navy Guy..... Best of luck with your transducers.
They very likely will bother each other. You could mount one on a pole off the front of toon and pull it up when under way. It may still bother but it would be less likely. I have a transducer on my trolling motor and one on the bracket at the back of the tube and they don't bother each other.
