Thank you for purchasing your new Bushnell NatureView®Binoculars.
This manual will help you optimize your viewing experience by explaining how you can adjust the binocular
to your eyes, and how to care for this instrument.
Read these instructions carefully before using your binocular.
EYE ADJUSTMENTS
How to Adjust for Distance Between Your Eyes
The distance between the eyes, called “interpupillary distance,” varies from person to person.
To achieve perfect alignment of lens to eyes, follow these simple steps:
1. Hold your binocular in the normal viewing position.
2. Grasp each barrel firmly. Move the barrels closer together or further apart until you see a single
circular field. Always re-set your binocular to this position before using it.
How to Adjust for Individual Eye Strength
As individual eyesight varies from one person to another, your Bushnell NatureView binocular has a diopter
setting feature which allows you to fine-tune the binocular to your vision. Follow the focusing instructions
on the next page.
EYECUP ADJUSTMENT
Your Bushnell NatureView binocular is fitted with twist-up eyecups designed for your comfort and to exclude
extraneous light. For users without eyeglasses, twist the eyecups up, rotating the eyecups counter-clockwise
until they lock into the fully “up” position.
If you wear glasses, make sure the eyecups are in the down position — this will bring your eyes closer to the

binocular lens, allowing you to see the full field of view. To lower the eyecups from the full “up” position,
rotate them clockwise. The eyecups may also be left at positions “in between” fully up and fully down, which
may suit some individuals better.
FOCUSING
1. Adjust the interpupillary distance by adjusting the center hinge until you see a single circular image.
2. The diopter adjustment ring is located directly below the right eyecup. Make sure the diopter adjustment
is set to “zero” for now: raised index line on the diopter ring is lined up with center arrow (or white dot,
depending on your model) on the -/+ scale. (see photo). Keep both eyes open at all times.
3. Using the attached lens cap or your hand, cover the objective (front) lens on the right side of the
binocular as you look into the eyepieces.
4. Using the center focus knob, focus on a distant object with fine detail (e.g., brick wall, tree branches,
etc) until it appears as sharp as possible on the left side.
5. Uncover the objective lens on the right side, and cover the left
objective lens while continuing to view the same object.
6. Rotate the diopter adjustment ring to bring the object into focus
in the right side of the binocular. Avoid over-turning or forcing the
diopter mechanism. If you are unable to bring the object into focus
in the right side by adjusting the diopter ring, make sure the left
side is still focused and that the center focus knob was not moved
from its original setting. The diopter adjustment only affects the
right side.
7. Your binocular should now be adjusted for your eyes. Focusing
for any distance can now be done simply by turning the center
focus knob. Make a note of the diopter setting you made (index
line position relative to the -/+ scale) for future reference.
