IPD
The eyecups on the Crossfire binocular twist up and
down so any viewer can take advantage of the long eye
relief and enjoy comfortable, full-field viewing.
With eyeglasses or sunglasses,
retract the eyecups.
Without eyeglasses or sunglasses,
extend the eyecups.
Adjusting the Eyecups.
The twist-up eyecups are built on a solid frame and
covered with rubber.
Adjusting the Interpupillary Distance.
The interpupillary distance (IPD) is the distance
between the centers of the left and right eye pupils.
Match the IPD of your eyes
to that of the binocular by
rotating the binocular barrels
inward or outward until you
see a single image that is free of
shading.

Focusing the Binocular.
Choose an object that is about 20 yards away from you
and follow this two-step process to properly adjust
the focus. Be sure to stay in the same spot until you
have adjusted both the center focus and diopter.
1.Adjust the center focus – Start by closing your right
eye or covering the right objective lens with your hand.
Focus your left eye on the
object and adjust the center
focus wheel until the image is
in focus. Leave the center focus
in this position as you adjust the
diopter.
2.Adjust the diopter – Start by closing your left eye
or covering the left objective lens with your hand. Look
through your right eye and
adjust the diopter (ring found
on the right eyepiece) until the
object is in focus. Make note of
this diopter setting in case you
need to set it again.
From this point on, you will only need to use the center focus dial.

Maintain the optical brilliance of the Crossfire binocular
by keeping the lens surfaces free of dirt, dust, and oils.
Protect Lenses While Out in the Field.
Caring for the Lenses
Make use of the rainguard and tethered objective lens
covers to protect the lenses when not viewing. Store the
Crossfire in its custom carry case.
Keep Lenses Clean.
Along with normal use comes the need to clean the
binocular lenses. Follow these guidelines for cleaning:
1.Remove any dust or grit from lenses before wiping.
Use a can of pressurized air or soft camel hair brush
(acrylic optical brushes also work well).
2.Clear lens of smudges, fingerprints, or eyelash
oil.
Fog the lenses with your own breath and wipe with
the non-abrasive lens cloth included with the Crossfire
binocular.
Cleaning fluid and optical paper can also be used. However, you
should never use facial tissue, heavy cotton, or flannel clothing
on lenses—these materials can scratch the lens surfaces.
