Setting up the diamondback scope

In this Vortex Optics review, we will outline for you all the features of the two most common Vortex Optics Diamondback Spotting Scopes; 20-60×60 and 20-60×80. Both scopes feature exact same specifications apart from the slight difference in the objective lens diameter. We will also review some of the closely competing models so you have several options to choose from.


Heading out for some sporting, hunting, or camping? Want something that will capture all your target in finer detail? Vortex Optics Diamondback Spotting Scope could be what you are looking for.

This scope is endowed with generous optics that comes from its widened objective lens, multicoated lenses, and the high-quality glass used. This scope doesn’t sacrifice anything in pursuit of giving you image clarity.

With a wider objective lens, the Diamondback can help you spot tiny, fast-moving objects with much ease. Resolution and contrast are taken care of by the top-quality glass used. The adjustment knobs are also strategically placed and have a clicking mechanism to signify a shift in settings.

Although some people prefer the straight body scopes due to their speedy target acquisition, angular ones too are advantageous in certain situations. This design enables low mounting which results in stability of the scope in windy conditions. Angled design also allows the use of lighter and portable tripods.

Weather elements, dust, and debris can coat on the lens and interior of a scope leading to limited optics. To do away with that, Diamondback is equipped with an O-ring seal to keep out dust, debris, and moisture. Nitrogen is also present in the scope rendering it fog and waterproof.

Vortex Diamond black doesn’t lock out those who wear glasses. Although not impressive, the eye relief works fairly better under low power. Remember even under low power, this spotting scope still delivers stunning images. Also, the adjustable eyecups can be twisted up or down for comfortable viewing without the need to remove your glasses.

We have already pointed out that this scope’s clarity is superb. However, the scope is a beginner’s model, clarity gets muddled under higher magnification. This should be expected and it certainly doesn’t bother many people since from 20 to even 50X, you can still obtain well-detailed images.

Diamondback’s design goes far in ensuring the device is safe from any conditions by protecting some of its delicate parts like lenses from harm. ArmorTek technology which consists of the ultra-hard scratch-proof coating is applied on the lenses to ensure they remain in a good condition for long.

Optical ability

Besides weight, waterproofing ability, and design, most enthusiastic outdoor individuals will consider a scope with the best optics even if the other factors do not align with their expectations. You would rather use a slightly heavier scope with exceptional quality imaging rather than a paperweight item that displays shaky images, right?

First, Diamondback scopes have wider objective lenses between 60 and 80mm to permit adequate light into the scope. Dielectric Prism and XR Anti-Reflective lens coatings also contribute to the light gathering ability of the scope thus making it optically powerful.
