Abstract: A novel archery device which defines the position of the arrow rest so that upon release of the bowstring the arrow is center-shot, i.e., it will fire straight ahead with optimum flight. The device has a visible light source arrow rest adjustment fixture which is temporarily secured to existing site mounting holes on a riser portion of a strung bow and includes an aligning component. The aligning component can move both laterally and pivotally so that a light emission from the fixture can transverse the entire length of an arrow attached to the nock point/portion of the bowstring and rest on a properly positioned arrow rest so that the arrow when fired has optimum flight. The light source can be a visible light beam, a laser light beam, and the like. The fixture is simple, lightweight, portable and accurate. The fixture can be easily removed prior to shooting the arrow.
