Abstract: A two handed bow and a bowstring release mechanism for launching an arrow along a shooting axis includes a riser, a pair of flexible limbs mounted on the riser and a bowstring connected between the free ends of the limbs. A pair of handgrips are pivotally mounted on the riser. The bowstring release mechanism is carried by a harness adapted to be worn by the archer and includes a body member having an elongated bowstring opening for receiving the bowstring and a pair of retaining arms pivotally mounted on the body member to selectively close and open the bowstring opening. A cam and electrically operated plunger operate the retaining arms to selectively close and open the bowstring opening. A retractable arrow rest is mounted on the riser and includes a shaft engaging surface for positioning the arrow along the shooting axis when the bowstring is in its full draw position.
