ABSTRACT:
A bow sight particularly suited for use on bows wherein the draw rating and hence arrow trajectory may be varied. A base of the sight has a forward extension on which is pivotally mounted a carrier having a sighting post. The base extension also supports a bridge having an inclined surface provided with elevation indices visible to the archer during aiming of the bow. The base extension and the carrier jointly provide stop means to retain the carrier and its sighting post in a selected elevation setting. A stop element is positionable within one of a series of recesses in the base extension corresponding to the bow draw rating. The stop element is sequentially engageable with a multitude of radially grooves formed in the carrier. Vertical adjustment of the carrier is through an arc the magnitude of which arc and the distance between carrier elevational settings being determined by the distance of the stop element from the carrier pivotal axis.
