3children, I have looked at the cams, I know how Darton gets the patents. It isn't because he designs them I promise you.
It is the same cam system used on the Air Raid. Though the look different with different cut outs and a slightly different shape they function exactly the same way. They are both binary cams with a split yolk attached to the pay out lobes to equalize cam lean.
Bowtech, Elite, Mathews, Darton, Martin, Parker, and a host of other manufacturers make dual cam bows. Whether they are the original dual cam designs with split yolks attached to the limb tips or a binary cam on one type or another.
