ABSTRACT:
The improved draw check of the present invention includes a support plate, a device for affixing the rear surface of the support plate to the window of an archery bow adjacent the bow arrow rest, and a resilient arm secured, preferably pivotably secured, to the exposed front surface of the support plate. The arm is a single blade and includes a portion adapted to contact the outer margin of an arrow when the latter is on the arrow rest for shooting from the bow. That portion of the arm includes a leading end and a trailing end, the leading end having a part projecting toward the support a greater distance than the trailing end projects toward the support.
With this arrangement, the archer can draw an arrow (while on the bowstring) on the arrow rest back past the check's leading end, thus causing it to suddenly move toward the support, and then further back past the trailing end, causing a further sudden movement of the draw check toward the support, in both cases signaling the position of the arrow.
