Thank you Skip

I understand the willows leafs passing through weeds better, and that you like to fish hydrilla. Do you know anything about the sounds produced. One blade company produces videos where you can see the blades spin in a tank and actually listen to a recording. However they all sound the same to me and no way they could in reality. Each would have it’s signature sound. Sound waves underwater are distorted, but to a fish would be different. I want to ring the dinner bell.
