Here's what Prodigy has to say about the Px3:
The PX-3 is an overstable, beaded putter that will help players throw accurate, consistent shots. It resists turning over at high speeds and glides forward before a predictable overstable finish kicks in at the end of its flight. The PX-3 has a larger bead than the PA-3 and is useful for both throwing and putting.
