How to use the XTR II Riflescope
Eyepiece Focusing
The eyepiece can be focused so that the reticle appears
sharp and black. Adjusting the focus is quick and easy
to do, just follow this procedure:
1. Point the scope at the sky or a plain wall and take a
quick glance through the scope. If the reticle appears
sharp and black, no further adjustment is necessary.
2. If the reticle does not appear sharp and black, take
quick glances through the scope while rotating the
focus ring until the reticle pattern is sharp and black.
NOTE: Do not look through the eyepiece as you turn
the focus ring. Your eyes will adjust to the out-of-focus
condition.
Parallax/Focus Adjustment
– Parallax adjustment is not available on 1x-5x
and 1.5x8x models –
Parallax is the apparent movement of the reticle in
relation to the target when the eye is not directly in
line behind the center of the scope. Images from
different distances focus in front of or behind the
scope’s reticle. Parallax is more noticeable with higher
magnification scopes.
To use the parallax/focus adjustment, rotate the knob
on the left side of the adjustment turret until the
numeral corresponding to the known target distance
lines up with the reference mark. If the distance is
unknown, rotate the adjustment knob until the target
image is sharply focused.
When the scope is set parallax-free for the distance
you are viewing, you should be able to move your eye
side-to-side or up and down without seeing the reticle
move appreciably in relation to the target.
