Abstract
A bowstring release for balanced release of the bowstring of an archery bow includes a pair of movable jaw members. Each jaw member includes a pair of lower and upper engagement portions spaced from one another in the linear direction of the bowstring in its uncocked disposition. The upper and lower engagement portions of the jaw members are movable into engagement with the bowstring above and below the vertical midpoint of the bowstring. Accordingly, when the nock of the arrow is disposed at the vertical midpoint of the bowstring, the bowstring release device applies substantially equal drawing force to the bowstring above and below the nock of the arrow during cocking of the bowstring and simultaneously releases and bowstring with a balanced release.
