Binoculars are not intended for looking at the sun, or any other
intense light source. Such viewing could damage the retina and
cornea of your eyes—even to the point of causing blindness.

The Viper binocular comes with a one-piece rainguard
that covers the eyepieces. For convenience, the
rainguard can be attached to the
neckstrap where it is within easy
reach. Simply slip the neckstrap
through the attachment point on
the rainguard before connecting
the neckstrap to the binocular.
The Lens Covers
The soft case of the Viper provides protection for the
binocular when not in use. A belt
loop attachment on the back of the
case allows for an easy carry in the
field.

binocular and repeat the process for the left barrel.
The Neckstrap
1.Push a few inches of the
strap through the neckstrap
attachment point on the
binocular.
2.Loop the strap over the
attachment point, then
thread the strap through
the strap buckle.
3.Secure the end of the

through the strap loop.
IPD
5
The multi-step eyecups on the Viper 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.
Customizing the Viper

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 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 Viper binocular
by keeping the lens surfaces free of dirt, oils, and dust.
Protect Lenses While Out in the Field
Caring for the Lenses
Make use of the rainguard to protect the lenses when
not viewing. Store the Viper in its 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 Viper 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.
