ABSTRACT:
A cross bow has a bow prod including two symmetrical halves which are mounted on two symmetrical bow prod mounts. The bow prod mounts are pivotally mounted on a fore end portion of a cross bow stock and movably connected to a slide, the slide performs longitudinal motion, when the cross bow is being cocked, thereby turning the bow prod mounts so that when one of the mounts is turned clockwise by some angle, another one is turned counter clockwise by the same angle, so as to increase the distance between the ends of the bow prod halves to which a bow string is attached and to thereby increase a bow prod tension for shooting.
