ABSTRACT:
A traditional sling shot is provided with a sighting mechanism on its upper elastic strap, typically a plurality of marks spaced apart along the strap in a vertical array of horizontal rises, colorations, or channels on a strap alignment side opposite the sling shot handle when the strap is loaded and stretched back into firing position with the handle horizontal and the strap generally vertical. The marks are calibrated to represent respective distances a shot of known size and weight will travel when a respective mark is aligned between the user and a target. The rise may comprise a ring, such as an elastic ring, around the strap biased to remain in a selective position on the strap but adjustable by sliding or rolling the ring along the strap to a preferred position.
