ABSTRACT:
A bow square for checking and adjusting the bracing height, nocking point and kisser location of an archery bow. The device is generally T-shaped and includes a scale-marked bar for bracing height measurement, and a transversely extending cross arm. The cross arm carries lineally spaced tab-like fingers for stressingly engaging opposed surfaces of a taut bow string seated in lineally spaced off-set notches. The fingers bear stressingly and resiliently against forcibly to distort the bow string passing therethrough, thereby frictionally securing the bow square in place on the bow string. The cross bar also carries a hinged scale pivotal between a functional reference position adjacent the bow string and a stand-by position retracted from the bow string.
