Vortex Diamondback Binocular
Review

Best value binocular

"Just tell me the best binocular for the money," our friend Linda asked us. She had just caught the birding fever, and she was enthusiastic.

She'd borrowed a binocular from the local nature center to go on a bird hike, and she knew right away that she needed one of her very own. She wasn't ready to fork over a major chunk of her savings for a high-end binocular, but she wanted something good.

"Is there something like that?"

Turns out there is.

It's the Vortex Diamondback HD — a high-quality binocular, with the best warranty a person could imagine. For around $200, its a binocular that performs more like binoculars in the $400-plus price class.

HD optics

The image is crisp, with good contrast, which makes it easy to see detail. The “HD” in the name refers to glass elements with low dispersion, which means they reduce the scattering of light that occurs when light passes through glass.

Careful design of the curvature and arrangement of the lenses also controls distortion. All of this reduces chromatic aberration and improves edge-to-edge clarity. High-quality coatings and well-engineered lens layout also enhance sharpness and maintain color fidelity.

Field of view

A wide field of view contributes mightily to the success and satisfaction of using binoculars. The wider the field of view, the more completely we are immersed in the visual experience.

With a view that is 393 feet wide at 1000 yards, the Diamondback has a wider field of view than most binoculars in this relatively inexpensive price range. This is one of the surprising qualities of the Diamondback. All of the other binoculars in the chart below cost more than the Diamondback but have a narrower field of view.

Best warranty in the business

Vortex offers an amazing warranty. Their VIP warranty, they call it. It is no less than an unlimited, lifetime warranty, fully transferable. Here it is in Vortex's own words:

VIP stands for a Very Important Promise to you, our customer. We will repair or replace your Vortex® product in the event it becomes damaged or defective—at no charge to you. If we cannot repair your product, we will replace it with a product in perfect working order of equal or better physical condition.

You see, it doesn't matter how it happened, whose fault it was or where you purchased it. If you ever have a problem, no matter the cause, we promise to take care of you. You can count on the VIP Warranty for all Vortex Optics riflescopes, prism scopes, red dots, rangefinders, binoculars, spotting scopes, tripods and monoculars. NO RECEIPT NEEDED.

Note from Birdwatching Dot Com... We have been selling Vortex binoculars to our customers for over 25 years, and we have found Vortex true to their word. They always, always, always come through and fix or replace a binocular that has experienced a mishap. They do it for free.

This warranty is one of the reasons that schools and youth groups often invest in a class set of Diamondbacks. They're protected if one gets dropped!

 We feel very good when we sell a Vortex, because we know that our customer will be taken care of.

Other sizes of Diamondbacks

There is a whole family of Diamondbacks, from quite small to quite large.

If you're not sure which Diamondback to order, you can't go wrong with the 8x42. It's the standard and the sweet spot.    

For lighter weight, look at the 8x32 or 8x28.

For maximum brightness in dark conditions, you might consider the 10x50 or 12x50. These, however, are heavier than the 8x42.

If you want more magnification and your hand is very steady, you might want the 10x42.
