Thank you for purchasing your new Bushnell® Forge™ 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 the instructions carefully before using your binocular.
NEVER LOOK DIRECTLY AT THE SUN WITH YOUR BINOCULAR,
AS IT MAY CAUSE SERIOUS DAMAGE TO YOUR EYES
EYECUP ADJUSTMENT
Your Bushnell Forge binocular is fitted with eyecups
(Fig. 1, next page)
that provide a comfortable view of the full image
and help to exclude extraneous light. For use without eyeglasses or sunglasses, twist up the eyecups
(Fig. 2)
. This will place
your eyes farther from the binocular’s ocular lenses, at the correct eye relief distance, allowing you to see the full field of
view.
IPD (INTERPUPILLARY DISTANCE) ADJUSTMENT
The spacing between the pupils of your eyes, called “interpupillary distance,” varies from person to person. To match your
binoculars to your IPD or “eye to eye” width:
1. Point them at a white wall or blank area of the sky. Hold the binoculars and view through them as you normally would.
Don’t worry about focus yet.
2. Grasp each side of the binocular firmly. Move the left and right sides closer together or farther apart
(Fig. 3, next
page)
until you see a single image with no shaded areas.
FOCUS AND DIOPTER ADJUSTMENT
1. First, adjust the eyecups and IPD as described in the previous sections.
2. Using the attached lens cap or your hand, cover the objective lens on the right side
of the binocular.
3. 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 when viewed through
the left side of the binocular.
4. Uncover the objective lens on the right side, and cover the left objective lens while
continuing to view the same object.
5. Rotate the diopter adjustment ring located directly below the right eyecup
(Fig. 4)
,
NOT the center focus knob
to bring the object into focus in the right side of the
binocular.
Be sure to unlock the diopter ring
first by pulling it up
(see Fig. 4, 10x30
model does not have a locking diopter ring)
. Avoid over-turning or forcing the
diopter mechanism. If you are unable to bring the object into focus for your right
