Given that the bronze through-hull Structure Scan transducer is $1200+, I’m not surprised that you would try the skimmer. Just remember that you’re going to have to be sailing flat (or motoring) in order for it to work with any degree of reliability, or even be underwater at all, given heeling; and there may be enough turbulence off the transom that it won’t read well, unless you’re just barely making way.
Also, at the transom, you’ll bee seeing what the bow already passed, rather than what’s below it.
