3D Real Vision Transducer placement (Yacht)

[watsala]

I measured the angle of the hull today in the bilges - its about 25 degrees so the twin real vision transducer should be suitable I think.

I was planning on mounting the same distance from the front of the yacht, but they might be slightly different distances from the center line. Does this matter?

They would also be on the hull slightly after of the front of the keel. Again is this ok or do they need to be forward of the keel?

Thanks again.
