Owner’s Manual
Congratulations on your purchase of a pair of precision-crafted binoculars.
Please take a few moments to familiarize yourself with the contents of this manual. By following
a few simple procedures and providing minimal care, you will find that your new binoculars will
give you many years of superb viewing.

How to use your binoculars:
Your binoculars are premium-quality optical instruments designed to provide many years of
reliable service. To customize your binoculars for the highest level of performance, we
recommend that you make the following simple adjustments.
Interpupillary distance:
Interpupillary distance is the distance from the center of your left
eye to the center of your right eye. The distance between the
centers of the two eyepieces of your binoculars should be the
same. You can adjust this distance by squeezing the two
binocular lens barrels together or by pulling them apart.
1) Make this adjustment while you are looking through your binoculars at a subject that is more
than 100 feet away.
2) Focus the eyepieces until you can clearly see your chosen subject. Do not be concerned if
your focus is less than perfect. The next procedure will optimize your focus.
3) If the eyepieces are too far apart, you will see two distinct image circles. Squeeze the lens
barrels together until the two image circles merge into one circle.
4) If the eyepieces are too close together, the two image circles will overlap. Slowly move the two
lens barrels apart until the two image circles appear as one.
The binoculars have either a center focus wheel or eyepieces that can be adjusted individually to
obtain the best focus.
Center focus wheels adjust both eyepieces at the same time. The wheel is located between the
barrels. To adjust the focus, aim the binoculars at a distant object and turn the wheel until the
image is clear and sharp in the left eyepiece. To focus the right eyepiece, follow the steps below.
Diopter Adjustment:
Since one eye is usually slightly stronger than the other, your center focus
binoculars feature the Diopter Adjustment to compensate for this
1) During daylight, view a subject from at least 100 feet away.
2) Close your right eye, but refrain from squinting.
3) Turn the center focusing wheel of your binoculars until you have a clear view of your subject.
4) Close your left eye and open your right eye. Do not readjust the center focusing wheel. Instead,
gently rotate the eyepiece first in one direction and then in the other until the subject appears
sharply in focus.
5) Now open both eyes. You should have a clear view of your subject and your eyes should not
feel strained.
For future use, you will have to adjust the center focusing wheel only to observe subjects,
regardless of distance.
NOTE: The right eyepiece has a scale with a plus sign, a minus sign, and a zero. Note that the
position of the indicator mark against this scale is your own personal setting. Use this as a
reference point if you need to realign your binoculars after somebody else has used them.
Binoculars that do not have a center focus wheel have eyepieces that focus individually. To focus
the right eyepiece, close your left eye and turn the right eyepiece until the image is sharp. Then
close your right eye and focus the left eyepiece in the same manner. Adjust as needed until you
have a perfectly focused image. Objects at varying distances will need to be refocused using the
proceeding technique.
Binocular features:
Fold-down rubber eyecups:
The binoculars have soft rubber eyecups to protect eyeglass lenses from being scratched and to
reduce the amount of distracting bright light reaching your eyes. If sunglasses or eyeglasses
hinder your view, simply fold down the rims of the rubber eyecups. Return the rubber eyecups to
their normal position when finished to reduce stress on the rubber compound and to prevent the
rubber from cracking. On the other models the eyecups are extended or retracted by twisting
Optical lens multi-coatings:
The lenses and prisms of your binoculars have been treated with the finest quality coatings for
better performance. The front lenses of many binoculars (the objective lenses) have been coated
with as many as 12 layers of compounds that filter out unwanted ultraviolet and infrared rays,
increase light transmission, reduce out-of-phase light rays, and enhance color purity and contrast.
These quality coatings may give the lenses of your binoculars a distinctive green hue.
Care of your binoculars:
1) Always treat your binoculars with care.
2) If any of the lens surfaces need cleaning, breathe on the lens and gently wipe with the cleaning
cloth included with your binoculars. If extensive cleaning is needed, use camera lens cleaning
tissues and lens cleaning fluid. Never use cleaning cloths or liquids designed for eyeglass lenses.
They may damage the coatings on your binocular lenses.
3) Always store your binoculars in their protective case or pouch.
4) Protect the lenses by using the lens caps when not in use.
5) Keep your binoculars secure by using the supplied neck straps or cords whenever possible.
6) Shock-resistant binoculars are carefully constructed to withstand rough treatment, however,
this does not mean that they should be intentionally abused.
WARNING! CHOKING HAZARD – Small parts. Not suitable for
children under 3 years.
