Any suggestions on what transducer is best for offshore for a 7612xsv?

garmin gt51M

I just put the thru hull model on my boat. I have a transom mount version I’m about to send back if you are interested. (out of stock everywhere right now)
From what i understand Garmin had to stop making the gt51m due to some patent issue. Now they offer the CV model transducer that is missing the down element.
