Subject: Re: Lowrance side-imaging: Is the surface visible?

Very interesting pic. It was always my understanding that the surface is where the boat is in the image and that anything between the boat and bottom is suspended in the water column. Meaning that those floats would be 10 feet down in the water. Since that is unlikely then I would imagine that the image is actually being produced by a reflection of the ultra sound waves reflecting from the bottom to the floats and back thus showing the image 10 feet under the surface.
