Just watched the video. They really didn't test the sonic system. They did a brief mention, when they compared the growth on the keel (which does not benefit from the system) and the hull. The keel had barnacles and the hull did not...so a favorable comment.

KRYG,I feel may have made a valid point about them working with an aluminum hull. I had always heard they didn't work but chances are most of that input came from glass or wooden hull owners. If one thinks about it, it makes sense.

If it worked great we would have read much more about this system...

Hi Cadence,

Thanks for your comments - My understanding after some research, store bought Ultrasonic units of different brands they can't live up to their claims. It seems their frequency are not effective - As you know in my earlier post I had a custom build unit in NZ by an electronic engineer. If you read the installation manual, he provides a there is a specific way to install them on Glass boats. I have no idea if it works or not?

However, in my case this year I saved slipping fees and antifouling cost which more than paid for the Ultrasonic unit which cost NZ $700 for my boat. The designer on his website confirms Aluminium and steel hulls are the best conductor for Ultrasonic transmission.
