Abstract: A bow sight is disclosed that provides vertical adjustability by movement of a finger of an archer's hand that is holding the bow in a shooting position. The bow sight comprises an elongated housing mountable adjacent a front edge of a bow with an elongated vertical screw member held rotatably by the housing. A sight carriage, with a horizontal sighting element extending therefrom, moves with the screw member as the screw member rotates in response to rotation of a knob at the lower end of the screw member.
