Abstract
A combined target sight and range finder with a bulls-eye pin and slotted sight plate that receives an adjustable “belly bar” is disclosed. A “set-in” procedure is used to establish a set-in distance and to generate a scale of various target sizes. The “set-in” procedure involves adjusting such that the bulls-eye pin is consistently aimed at the bulls-eye of a target, yet hits the target at a distance above the target. The archer moves progressively farther away from the target until a “set-in” distance at which aiming at the bulls-eye produces shots that hit the bulls-eye is reached. Various targets are presented at the set-in distance, and the belly bar is positioned such that the bulls-eye pin and belly bar frame each target. The belly bar can then later quickly be placed in its slot at the position corresponding to the target size, thereby accounting for the distance between the shooter and the target.
