I am considering the purchase of an Airmar P66-BL 600W 50/200 kHz Transom Mount Triducer for my HDS 5X sonar! I believe it is the equivalent of the B60 thru the hull model. I just cannot fathom the thought of cutting a 2 & 1/8" hole in the bottom of my boat so I am leaning toward the transom mounted version.

Are the Airmar transducers that much better than the junk that is bundled with the HDS units as a package and marketed by Lowrance/Simrad? By buying a better transducer maybe I can realize more of the potential this HDS 5X unit is supposed to provide and not have to spend the bucks for another stand alone sonar. Any thoughts on this would be greatly appreciated.
