Vortex Diamondback 10×42: A Top-of-the-line Binocular at a Reasonable Price

Whether you’re a hunter who wants to spot that elusive buck, a stargazing enthusiast who watches heavenly bodies and planets, a birdwatcher who doesn’t want to miss out on the scenic beauty, or a photographer who wants to take professional shots from a distance, you need a pocket-friendly binocular with superior optics. 

Vortex Diamondback 10×42 is one such glassing tool you need to give serious consideration if your budget is somewhat small.

And if you are a fan of Diamondback Classic, a lighter, more compact binocular with a better chassis and bridge will captivate you, for sure. 

These features enable you to glass, observe, stargaze or bird for longer periods before your arms wear out and your eyes strain. Even if that were the case, a tripod would help – and, fortunately, the instrument is compatible with one. At a decent price, you benefit from crystal clear and rich images with minimal chromatic aberration.

It doesn’t matter whether it’s raining or snowing, lenses are weatherproof. You can move through variable temperatures without worrying about the fogging up of the optics. 

Hence, before you go outdoors or make a purchase, let’s get to learn more about this amazing binocular.

Vortex Diamondback 10x42 – First Impressions

At first glance, the binocular comes off as stylish and esthetically pleasing. But looks can be deceiving – the product is tough, on the contrary. 

With a high tolerance against harsh weather and terrain conditions, you can be sure your beauty will survive to serve you another day. 

Blanketing the whole chassis is a rubber armor to decrease wear and tear in dusty, snowy or rainy conditions. In connection to that, when your hands become cold or wet, you still retain a full grip of both barrels, which are rugged with a rubbery finish to prevent accidental slips and drops that can damage the instrument. 

Even if you drop the binocular from a height, say, roof of a building, the damage is minimal.

Specification at a Glance

  • What does 10×42 mean? It means that magnification power is 10× and the diameter (or size) of the objective lenses (optics nearer the object) is 42 mm. Hence, you’ll be able to see an object that’s 10 times larger than what your eye perceives at a particular distance. 
  • Eye relief is 15 mm. That means 15 mm is the maximum distance you need to position your eye from the ocular lenses (optics nearer the eye) to see the image clearly.
  • Exit pupil is 4.2 mm.
  • At a distance of 1000 yards, you’ll see a field, which is 330 feet wide. And so, at 100 yards, the field of view should be 33 feet (do math for other distances).
  • The widest angle the field of view can cover equivalent to the linear distance is 6.3 degrees.
  • Close focus is 6.7 feet.
  • Consider the distance between your pupils. People’s head sizes; hence, interpupillary distances vary. Fortunately, you can use the diopter to adjust the distance to suit your head size. The minimum and maximum adjustments are 55 and 75 mm, respectively.
  • The instrument weighs 21.4-ounces, and is 5.1 inches wide and 5.8 inches high.

Important Features

  • Several layers of coating cover all the lenses completely to maximize light transfer. Thus, in low light conditions, images remain clear and bright. Moreover, these coatings prevent sun’s glares and reflections, which irritate eyes.
  • Prisms within both barrels have a covering of several layers of dielectric coatings to prevent light waves from falling out of phase. What results is an image with truecolor.
  • The manufacturer removed oxygen and replaced it with a heavier-than-nitrogen gas known as argon. As said, when temperatures vary, even slightly when it isn’t raining or snowing, the interior of both barrels remain clean and fog-free.
  • O-ring seals around the lenses, diopters and adjustment buttons prevent foreign objects (like debris, dust and moisture) from penetrating the inside; hence, damaging the prisms.
  • Rubber covering around the chassis provides a rubbery feel, which is essential to prevent loss of grip that can result to accidental drops.
  • Eyecups allow you to adjust viewing to suit your eyesight. No need to wear spectacles if you’re long- or short-sighted
  • There’s a diopter on the right to enable you to adjust the interpapillary distance to suit your head size.
  • Awesomely, especially if you’re a photographer, you can mount your binocular on a tripod or a car window to prevent shaking of your hands for steady images.

Vortex Diamondback 10x42 – Field Test Results

As said, Vortex built the binocular to be tough (and so, built to last) but esthetically pleasing. No instrument combines these two attributes excellently than the Diamondback binocular. 

Drop it from the roof of your house and the rugged, rubbery armor absorbs most of the shock and damage upon hitting the ground.

Adding to the damage resistance is the lightweight magnesium material making up the chassis (Vortex replaced polycarbonate with magnesium – and polycarbonate is tough, as well). 

Furthermore, you can be sure your binocular will survive a hard knock. 

And, oh, not to mention, in case you damage your Diamondback 10×42, Vortex’s lifetime warranty allows you to replace or repair it. No deal can get more awesome than that.

What Makes the Vortex Diamondback 10x42 Unique?

Other than being built by a company who specializes in optics, the Diamondback 10×42 is a one-in-a-million product. No instrument, thus far, has exhibited two attributes, which are somehow opposing each other – beauty and toughness. 

More captivating about Vortex’s ingenuous innovation is its ability to meet your high-end requirements at a surprisingly lower price than competitors in the same price range. 

Definitely a big bang on your buck, the binocular is one such tool a serious glassing enthusiast should possess. And the optics specialist is generous to give you a lifetime warranty. What more can you ask?

Vortex Diamondback 10x42 Strength

  • Vortex is generous to give you a lifetime warranty. That’s a deal that’s difficult to come across now that you have the benefit of knowing it.
  • Excellent optics at a reasonable price. You can enjoy high-end optics at half the price: dielectric prisms and lenses, which are fully covered with multiple layers to enable low-light glassing.
  • Beautiful but tough. The sleek, rubbery and velvety appearance is nice to look and feel. Other than compactness and lightness, owing to magnesium makeup, the instrument is resistant to wear and tear in harsh conditions, which often characterize hunting or birdwatching expeditions.

Vortex Diamondback 10x42 Limitation

  • No product is perfect. Products will always remain work in progress and they’ll only get better.
  • Closed bridge design makes for difficulty in holding the barrels with a single hand.
  • While compatible with tripod adapters, there’s a problem – buying a separate accessory.

Final Thoughts

As a serious, curious and enthusiastic birder or hunter, you’re missing out greatly if you haven’t yet laid your hands on this beautiful but tough piece. 

A manufacturer who specializes in optics is generous to give you a lifetime warranty (you can be sure to replace and repair your instrument when it breaks down). 

Anyway, Vortex built it to last, so it’s unlikely you may seek the warranty, unless you subject it unnecessarily harsh conditions, as in field tests (deliberate dropping, knocking and wetting). 

Otherwise, under normal field conditions of hunting or birdwatching, your binocular will survive to serve you another day.
