Cross hair adjuster for archery bow
摘要:
A sight scope for an archery bow is provided which consists of a telescopic tubular housing having a first segment mounted to a handle of the archery bow, so that a viewing end of the first segment can be positioned in front of an eye of an archer, with a second segment of the archery bow being adjustable thereto. A cross hair is carried within the first segment of the telescopic tubular housing. A structure is for adjusting the height of the cross hair with respect to the adjusted length between the first and second segments of the telescopic tubular housing, so that the archer can focus on a target to try to hit the target with an arrow.
