This Crossfire II riflescope features an image focus/parallax adjustment
which provides maximum image sharpness and eliminates parallax
error.
Using image focus/parallax correction:
Be sure the reticle is correctly focused (see Reticle Focus on page 4).
• Rotate the adjustable objective until numbers match the distance you
are shooting. Align yardage number to the indicator arrow on scope
body.
• Check for proper setting by looking through the scope to verify image
sharpness and, at the same time, look for reticle shift while moving
your head back and forth. The setting is correct if there is no apparent
movement between the reticle and target while your head is moving back
and forth. If there is apparent movement, adjust the focus knob slightly
until the movement is eliminated.
• When properly set, the target image should be sharp and crisp.

What is Parallax?
Parallax is a phenomenon that results when the target image
does not quite fall on the same optical plane as the reticle
within the scope. When the shooter’s eye is not precisely
centered in the eyepiece, there can be apparent movement of
the target in relation to the reticle, which can cause a small
shift in the point of aim. Parallax error is most problematic
for precision shooters using high magnification.
Match the shooting yardage to indicator
dot. 50 yard setting shown.
