Basic OperatiOn
Adjust the eyecups
The eyecups on the Viper®compact binocular twist up and
down so any viewer can see the full field and enjoy comfortable
viewing—with or without eyeglasses.
When not using eyeglasses or
sunglasses, keep the eyecups fully
extended. For the best viewing
when viewing through eyeglasses,
twist eyecups down.
Adjust 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 so that you see a single image that is
free of shading.
Objective Lens
Please read the entire manual before using your new optic.

inward or outward to line your
eyes up with ocular lenses.

Properly focus the binocular
For the best views, follow this two-step process to properly adjust
the center focus and diopter. Choose an object that is about 20
yards away from you and stay in the same spot until you have
adjusted the binocular for your eyes.
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 wheel.

Carry Case
The Viper’s protective case provides safe storage between viewing
sessions. The carry strap is already attached to the case.
Lens Covers
The Viper comes with a rainguard for the ocular lenses and
tethered objective lens covers. Use these covers to protect the
lenses whenever you are not viewing.
Neckstrap
Securely attach your binocular to the binocular strap:
1. Thread the end of the
strap from the bottom
and up through the strap
attachment loop.
Note: Please do not thread a metal ring directly onto the strap attachment
loop when attaching rings or clips for other after-market equipment. Instead,
use nylon zip ties according to the manufacturer’s instructions.
2. Hold the buckle
and thread the end
of the strap through
the buckle.
3. Adjust the overall
length and pull the strap
webbing tight so it is
secure within the buckle.

Lens Care
Maintain the optical brilliance by keeping lens surfaces free of
dirt, oils, and dust.
Protect lenses while out in the field
Use the provided cover to protect the lenses. If the optics are
exposed to moisture, keep the cover off and allow the optics to dry
out completely before putting in the case for storage.
Keep lenses clean
In order to enjoy the best views through your Viper binocular,
take time to regularly clean the exterior lenses:
1. Remove any dust or grit from lenses before wiping. Use
a can of pressurized air, soft camel hair brush, or an acrylic
optical brush.
2. Clear lenses of smudges, fingerprints, or eyelash oil. Fog
the lenses with your own breath, then use a non-abrasive lens
cloth to clean the lenses.
Note: Use lens cleaning fluid and
optical paper to clean lenses. Never
use facial tissue, heavy cotton, or
flannel clothing on lenses—these
materials can scratch the surface of
a lens.
Caution: 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.
