"Mathews" has made a dual cam before. It was way back in the day, and Mat Mcpherson used his old company name which I believe was Mcpherson Bows. He later sold the name when he came up with the idea for single cam technology. Upon reintroducing the dual cam idea (for the benefit of speed) in the new Monster series bows he bought the name Mcpherson Series bow back. Thats why you will notice they dont consider the Monster bow a true "Mathews."
