BASIC OPERATION
Adjust the Eyecups
The eyecups on the Diamondback®HD 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 wearing glasses,
twist eyecups down.
Adjust the Interpupillary Distance
The interpupillary distance (IPD) is the distance between
the center of your left and right pupils. Match the IPD of
your eyes and your binocular by rotating the barrels in or
out until you see a single image free of shading.

Properly Focus the Binocular
For the best reults, follow this two-step process to properly
adjust the center focus and diopter. Choose an object about
20 yards away 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.

LENS CARE
Maintain the optical brilliance of your binocular by keeping
lens surfaces free of dirt, oils, and dust.
Protect Lenses While Out in the Field
Make use of the provided eyepiece and tethered objective
lens covers to protect the lenses when not viewing. If the
optics are exposed to moisture, keep the caps off and allow
the optics to dry out completely before putting them in the
case for storage.
Keep Lenses Clean
In order to enjoy the best views through your 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.
