Instructions
Sight in your VX-3 scope with the adjustment dials on the top and right side of the scope. One click on the dial moves the scope's projected point-of-impact 1/4 inch (along the applicable axis) on a target of 100 meters. The purpose of sighting in your scope is to align the projected point-of-impact (the intersection of the crosshairs) with the actual point-of-impact (where the bullet hits the target). The top dial adjusts the vertical axis and the right hand side dial the horizontal axis.
Set the scope magnification as desired by rotating the variable power ring, adjacent to eyepiece, and by aligning the desired power setting with the dot on the top of the scope.
Adjust for parallax correction (if your model is so equipped) by setting the scope to the range to target. Parallax is the illusion of target movement often encountered while engaging targets at long ranges at high magnification. On VX-3 scopes, the parallax adjustments are made either on the objective lens (at the end of the scope) or on a dial located on the left hand side of the scope.
