ABSTRACT:
A bow tuning gauge has an elongated body and two sets of horizontal and vertical gauges attached thereto at either end. The gauge, when attached to an archery bow, enables the user to position an arrow shaft at a precise perpendicular state in relation to the bow. An arrow shaft is placed in two metal clips at the end of the horizontal gauges, which in turn are positioned by the vertical gauges. The arrow shaft is moved left and right until the arrow shaft is in proper alignment with the bow string (center shot). The vertical gauges are used to align the arrow shaft vertically across the tune hole. Once proper horizontal and vertical positions are found, the arrow shaft is slid back to bow string and the bow string may then be nocked. After center shot has been located, an arrow rest can be bolted on the bow in the optimum position, and the bow can be adjusted.
