Just wanted to say that I also mounted the side scan transducer reversed under the hull on our catamaran. It works extremely well. I had to cut a piece out of the trailer bunk for clearance, but the scan quality is the best I've seen on any installation.
Yes I think the return quality is far better in this location. Interesting the right hand channel has a better return and I think it has something to do with the larger surface area on that side. It would be an interesting test to mount the transducer as a skimmer with an aluminium plate backing. I suspect it reduces the surface interference when the returns hit it.
The angle of the hull on the right reflects more of the returning sound waves onto the face of the transducer. On the left side, you don't get that extra boost.
I'd guess that the difference is most pronounced at the outside of the right channel's range? It probably is much brighter as you get into the 100-200 foot range. But closer underneath the boat, the returns are just about identical, aren't they?
