Thank you for purchasing your new Bushnell® Legend® 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 Legend binocular is fitted with eyecups (Fig. 1, 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).
Fig. 1 Eyecup in “Down” Position (for use with eyeglasses)
Fig. 2 Eyecup in “Up” Position (for use without eyeglasses)
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 “inter pupillary distance,” varies from person to person. To match your binoculars to your IPD or “eye to eye” width:
- 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.
- Grasp each side of the binocular firmly. Move the left and right sides closer together or farther apart (Fig. 3) until you see a single image with no shaded areas.

FOCUS AND DIOPTER ADJUSTMENT
- First, adjust the eyecups and IPD as described in the previous sections.
- Using the attached lens cap or your hand, cover the objective lens on the right side of the binocular.
- 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.
- Uncover the objective lens on the right side, and cover the left objective lens while continuing to view the same object.
- 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. Avoid over-turning or forcing the diopter mechanism. If you are unable to bring the object into focus for your right eye by adjusting the diopter ring, make sure the left side is still in focus (repeat steps #2-4 if necessary). The diopter adjustment essentially provides “fine focus” on one side of the binocular (right only) to allow for slight differences in the vision of your left and right eyes.
- 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 your diopter setting (position of plus and minus marks on diopter ring relative to index mark on binocular below the ring) for future reference in case the ring is moved accidentally or by another person using your binocular.

NECKSTRAP ATTACHMENT
To attach the neck strap, thread the ends of the neck strap through the strap
lug (Fig. 5) on each side of the binocular, then back through the plastic
buckle on the strap (Fig. 6). Adjust the position of the binoculars on your
chest as they hang around your neck to your preference, by changing the length
of the strap section which passes through the strap channel and buckle by an
equal amount on each side.
Tug on the binocular to make sure it is securely fastened to the strap before
letting go of it. If you prefer to use an aftermarket strap that has metal
O-rings, attach them to a plastic zip tie placed on the strap lugs rather than
installing them directly on the lug, to avoid damaging the finish on the
binocular via contact with the rings.

TRIPOD MOUNTING
To attach the binocular to a tripod or monopod, unscrew or pull off the cap
which covers the threaded socket at the far end of the center hinge (Fig. 7),
and set it aside in a safe place. Use a compatible binocular tripod adapter
accessory (90o angle bracket), such as the Bushnell #161002CM, to attach your
Legend binocular to any standard tripod in a horizontal position to provide a
stable image during prolonged viewing.
WATERPROOF / FOGPROOF
Getting caught in a heavy downpour of rain, or accidentally splashing your Legend binocular during a boating excursion won’t be a problem. The binocular is manufactured and tested to withstand water exposure up to IPX7 standards. Fog proof protection is achieved from dry Nitrogen purging that removes all internal air, which can retain moisture.
CARE OF THE OPTICS
- Your Bushnell Legend binocular will provide years of trouble-free service if it receives the normal care you would give any fine optical instrument.
- Avoid sharp impacts. Set the binocular down gently on hard surfaces.
- Tug on the strap after attaching, making sure it is securely fastened to the binocular before placing it around your neck.
- Store your binocular in a cool, dry place whenever possible.
CLEANING
- First, blow or brush away any dust or debris on the lens (using “canned air” or a soft lens brush).
- To remove dirt or finger prints, clean with the supplied soft storage bag (made of washable micro-fiber cloth), rubbing in a circular motion. Use of a coarse cloth (including paper towels) or unnecessary rubbing may scratch the lens surface and eventually cause permanent damage. The included storage bag/micro-fiber cloth is ideal for the routine cleaning of your optics. Simply breathe lightly on the lens to provide a slight amount of moisture, then gently rub the lens with the micro-fiber cloth.
- For a more thorough cleaning, photographic lens tissue and photographic lens cleaning fluid or isopropyl alcohol may be used. Always apply the fluid to the cleaning cloth – never directly on the lens.
- To prevent potential damage to the optical coatings on the binocular’s lens surfaces, never use household window cleaning liquids. Avoid using facial tissue or clothing that may have fibers which can be abrasive and hold oils or dirt.
