Structure is also provided for adjusting the transverse launch trajectory angle to compensate for variations between bows or archers. The device has a bracket which can be attached to the bow, a pair of sight mounting members adjustably affixed to the bracket and adapted for axially mounting the sight, attachment structure for pivotally mounting the first sight mounting member to the bracket, attachment structure for mounting the second sight mounting member to the bracket such that the second sight mounting member can move arcuately about the first sight mounting member, an a user operated member which drives the second sight mounting member and which employs a detent member cooperating with a catch member thus permitting the second sight mounting member to be adjusted to thirty or more different positions.
