发明名称 Archery
摘要 To attain accuracy in the sport of archery, reference points are used. These reference points are constant and do not vary. The Inline sight gives the archer an added point of reference that increases accuracy in the horizontal dimension. This invention is unique in that the archer can be any distance from the target and always have an added reference point. The Inline sight uses a vertical line positioned between the archer's eye and the standard pin sight that is attached to the front of the bow to attain this added reference point.
