Abstract
A string tracking apparatus for archery arrows including a arrow having a hollow tubular shaft with a point attached to one end of the shaft. A nock is attached to the other end of the shaft and fletching is disposed near the nock for stabilizing the arrow in flight. A coil of flexible line is disposed within the hollow shaft and one end of it is attached to one end of the shaft. A hook-shaped catching structure is attached to the other end of the flexible line. In one embodiment of such structure, the hook-shaped catching device is frictionally disposed around the front end of the shaft or around the front end of the point attached to the shaft. In this embodiment, when the arrow is shot through an object, such as a turkey, the hook-shaped catching device will not pass through the object although the arrow may very well pass therethrough. If it is a turkey that the arrow has passed through, then the hook-shaped catching device will be attached to the turkey and the arrow will be sticking into the ground or laying on the ground. When the turkey runs away, the string within the shaft will unwind so that the hunter can find the turkey by following the flexible line.
