Xuqeru Premium Binoculars for Monovision Users 10x42 ED

---

A diopter adjustment compensates for differences between your eyes.
Most binoculars have one diopter ring (usually on the right eyepiece) plus a center focus wheel.

Dual diopter adjustment means each eyepiece has its own  diopter ring, which doubles the amount of accommodation available.

The benefits of dual-diopters is:

• Better for people with unequal vision or monovision (one eye for distance, one for near)
• Reduces eye strain and improves perceived sharpness and depth

The Xuqeru Optics binocular is designed for exactly this situation, with dual-diopter adjustment that most optics companies simply do not provide at any cost.

These conventional single-diopter adjustment designs have an accommodation range between +-2d or +-4d. Xuqeru gives you TWO adjustment rings, each +-4d, for a total range of +-8d.

The procedure is similar to single-diopter systems.

1. Looking through the left eye, use the center focus wheel to bring a distant object into focus.

2. Looking through the right eye, use the right diopter ring to bring the right eye into focus. YOU MAY BE DONE AT THIS POINT. IF NOT, CONTINUE:

3. If the adjustment ring stops before focus is achieved, use the center focus to adjust the right eye. 

4. Looking through the left eye, use the left diopter ring to bring the left eye into focus.

Xuqeru binoculars are IPX7 rated. This is accomplished with quality materials and especial attention to the seals and O-rings.

From the IEC (International Electrotechnical Commission), "IPX7 means the product has been tested for water immersion protection under the IEC 60529 IP rating system. Specifically, it means the enclosure can withstand temporary immersion in fresh water up to 1 meter deep for 30 minutes without harmful water ingress. "

Nitrogen fog-proof optics are optical devices (like binoculars, scopes, or camera lenses) that are sealed and filled with dry nitrogen gas to prevent internal fogging.

How it works:

• The optic is purged of humid air and filled with dry nitrogen.
• It’s then sealed with O-rings to keep moisture out.
• Because nitrogen contains no water vapor, there’s nothing inside to condense on the lenses.

The eye cups on these binoculars are a twist-up design. This mechanism does not change the focus, but is used to help set the distance between the lens and your eye (known as "eye relief"). Each side can be adjusted independently with detents at High-Mid-Low positions. Most eyeglass wearers prefer the "down" or Low position, while Mid or High/Extended is more common for use without eyeglasses.

The body of the binoculars is hinged at the center. Changing the angle of this hinge also changes the distance between the ocular lenses (the eyepieces you look through) and is how you adjust the binoculars for the distance between your eyes.

Binoculars are helpful in many outdoors activities such as hunting, scouting, sightseeing, whale watching, wildlife viewing, birdwatching, stargazing and more. We know fishermen who use binoculars to survey what lures and colors other fishermen are using and copying/avoiding their technique depending on their success (or failure!) Spectators at sporting events such as football, baseball, soccer, polo, golf, racing and more may also find binoculars helpful to bring distant action up close.

The minimum focus distance is 1.5m/4.92'. See the instruction manual for more detailed specs.

We have included a microfiber lens cleaning cloth that is suitable for gently cleaning the lenses without leaving lint behind. You may wish to moisten the cloth with clean water or any lens cleaning fluid available at photo/camera retailers, especially if you have persistent raindrops or fingerprints. It is important to check for any debris such as dirt or sand on the lens as well as the cloth before cleaning. DO NOT RUB THE LENS IF THERE IS DIRT, SAND OR OTHER DEBRIS ON THE LENS OR CLOTH. Remov
