1. Construction of Vortex Diamondback 10×42

The Vortex Diamondback 10×42 binoculars have a lightweight roof prism design. Besides, the body is made up of a robust polycarbonate material that is shockproof. As you would expect from any quality binoculars these days, the binoculars’ body is cased in a rubber armour coating.

Rubber coating has become so popular on practically all binoculars due to its numerous advantages. It protects the binoculars from scratches and bumps and acts as a superb sound absorber. You may be wondering why this function is so crucial to you?

Sometimes we accidentally strike our binoculars against our watch or rangefinder, which makes a sound. This sound will alert the birds or any other animals you are after, so you’ll have to go home in despair. Therefore rubber coatings absorb such sounds, and you have more chances of a successful hunt.

Moreover, it provides a good grip to avoid them slipping off your hands in wet weather.

2. Waterproof and Fog-proof Binoculars

Diamondback binoculars are completely waterproof and may be used in any weather. The placement of O-ring seals, which prevents even little water drips, is the science underlying this feature. This not only makes it waterproof but it also protects from dust and debris.

Most manufacturers use nitrogen gas for fog proofing, but Vortex has filled this piece with argon gas. Nitrogen gas works fine, but when comparatively, argon gas works more effectively.

As a result, your binoculars won’t fog up with the change in temperature.

3. Eyecups/Eye relief – Vortex Diamondback 10×42

Most users don’t care about eyecups, but they make a difference. The eyecups on these binoculars feature a twist-up mechanism, making viewing comfortable. Moreover, they offer a 16mm eye relief long enough for any user.

Eyeglass wearers mainly consider eye relief, whereas non-eye glass wearers ignore it. But we would suggest buying a binoculars with a long eye relief as you may have to use glasses in years to come.

4. Focusing – Vortex Diamondback 10×42 Binoculars

The focusing system in a binocular gives you more control over your binoculars. Some binos have a separate focus system for each barrel, making it difficult to focus both alike.

However, Vortex Diamondback 10×42 binoculars come with a central focus knob that adjusts focus for both barrels. The wheel is rugged, has an excellent grip,  and is smooth to adjust.

Some binoculars also have an extra focusing locking diopter on one of the barrels, primarily the right one. It is for those people who have differences in vision between their eyes.

First, they set the focus for one eye with the central focus wheel. Next, they adjust the focus for the other eye with the help of the diopter.

Thankfully, the vortex diamondback also has a right eye-locking diopter which can be helpful if you have differences in vision.

5. Optical System of Vortex Diamondback

This vortex model uses a lot of high-end components, which are further coated to produce quality.

6. Lens or Prism Coatings

The roof prisms on these binoculars are made of the popular Bak-4 glass instead of the cheap Bak-7 glass. This shows that the binoculars have been well made, ensuring quality in every possible way.

These prisms have been submitted to phase correction coatings. Such coatings keep light in their correct phases and provide high-resolution images that have better contrast.

Thanks to these, you won’t see any color fringing even when looking at areas of high contrast.

You may have noticed in the description that these binoculars are fully multi-coated. By completely multi-coated, they imply that all surfaces have received several coats, which aids in light transmission.

Therefore, these binoculars provide bright images and work perfectly in low-light conditions making them one of the best low-light binoculars. All the optical components perform one job, I-e, to provide quality which is in the form of exceptional clarity and razor-sharp images.

7. Field of View – Vortex Diamondback 10×42 Binoculars

Field of view is significant, especially when you are observing a bird taking its flight. The field of view these binoculars offer is 345ft at 1000 yards. Now maybe you need more than this, but for 10×42 binoculars, this is decent and wide enough. Yes, some binoculars even offer a 400ft field of view, but they cost you. Whereas, these are the best binoculars under $300.

8. Close Focusing Distance

A good close focusing distance in binoculars would be 6 feet or anything under it. Surprisingly, these binoculars offer the least possible close focusing distance, which is 5 feet.

If you have an interest in viewing butterflies and insects, then there can’t be a better option than these.

9. Vortex Vip Warranty

Vortex will fix any problem or deficiency that comes up in your binoculars. A lot of manufacturers offer warranties against their binoculars, but they are for some time.

However, Vortex offers a lifetime warranty for these binoculars, and the plus point is that the warranty can also be transferred to another user. Making them the best hunting binoculars.


The Vortex Diamondback 10×42 is a quality binocular with multiple high-end features. These binoculars deliver exceptional images that are clear and sharp. Their field of view makes them stand out from all other binoculars in this price range. It is affordable compared to its counterparts and offers the best blend of performance. If you are looking for a prime binocular that’ll last for a lifetime, then this is it.
