Congratulations on your purchase of a Diamondback
binocular—a great value for any outdoor experience.
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.
Caution:
The
Binocular Series
D IAMONDBACK
The bright images you’ll see with a Diamondback
binocular are the result of fully multi-coated optics,
working to increase light transmission throughout the
optical system. Phase correction, a coating on the prism
surfaces, further improves the color fidelity, quality, and
contrast for sharp imaging that is especially noticeable
under low light conditions.

The Diamondbacks are rugged roof prism binoculars.
The waterproof, dust proof, and internally fogproof
design features an internal focusing mechanism, o-rings
at all open points, and argon gas purging.
Rugged Design
Adjustable
Eyecup
The Diamondback binocular comes with two tethered
objective lens covers and 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 custom-molded case of the Diamondback provides
protection for the
binocular when not
in use. For an easy
carry in the field,
clip the woven
nylon neckstrap
onto the case.

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
strap by slipping it
through the strap loop.
IPD
The eyecups on a Diamondback 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, tapered
to fit the contour of the eye, 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 Diamondback 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 and tethered objective lens
covers to protect the lenses when not viewing. Store the
Diamondback in its custom-molded 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 lenses of smudges, fingerprints, or eyelash
oil.
Fog the lenses with your own breath and wipe
with the non-abrasive lens cloth included with the
Diamondback 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.
