Our Verdict: For everything long-range, tactical, and hunting, the D-790 scope is made for it. It’s a professional piece of gear that is on a level of its own. Unmatched performance is what the Bering Optics scope brings to the field.

Who is the Bering Optics D-790W Gen 3+ Best Suited to?

Either you want the best night vision scope for hog hunting or you’re looking for a professional scope for the workplace whether it be military or law enforcement. This is what the Bering Optics D-790W Gen 3+ was made for – serious business.

This scope has the works, so it’s no lightweight rig meant for popping off rodents. When long-range precision, long-range recognition, and unparalleled night vision performance is needed, this is one of those scopes that is well worth the cost for both a hunter and sniper.

How Does the Bering Optics D-790W Gen 3+ Perform?

This specific scope from Bering Optics is the D-790W 6.0x83 Gen 3+ night vision scope with model number BE73790HDUW. It has a high-definition optical system, an unfilmed micro channel plate (MCP), autogated tube, white phosphor screen, and manual gain. These are all features indicative of high-end quality that provides the best of the best of what Gen 3 can offer.

Not only is it made to provide ultimate night vision, but its fundamental features as a rifle scope are also just as impressive. It’s a fixed 6x scope that is well-suited to long-range performance with its ¼ MOA turrets, thought-out control placement on the scope, and a mil-dot reticle with dual color options.

Scopes of this caliber are far from cheap. They also tend to be big and heavy. This is true of the D-790 and must be expected as they are inherent drawbacks of high-end NVDs. If you need something more affordable, there are night vision scopes under $1000 that will fit the budget.

Features & Benefits

White Phosphor

There’s white phosphor, and then there’s white phosphor on a Gen 3+ tube. The D-790W is as good as it gets for Gen 3 night vision scopes with black/white imaging.  

The multi-coated lenses provide high-definition quality and high resolution of 64-72 lp/mm with a large 83 mm objective lens. Its optical quality puts it at the top as it outperforms other alternative scopes. With its HD optical system, it provides more than 20% better identification and light transmission at longer ranges.

With a white phosphor screen, detail and contrast is easily and quickly distinguished against the background allowing for fast target acquisition and identification. Many find the black/white imaging to be easier on the eyes and more natural, and the D-790W gives you that option to find out if it’s right for you.

With manual gain, you can also adjust the brightness to achieve the best balance between contrast and resolution for the conditions you’re in. Ultimate picture quality is the name of the game.

Gen 3+ Unfilmed & Autogated

Bering Optics doesn’t mess around. Their Gen 3+ scopes feature unfilmed tubes and autogating. Without the ion barrier film, electron loss is a non-issue once electrons are released by the photocathode. This results in a higher electronic signal which speaks to its excellent photocathode sensitivity.

Autogating is when the system automatically turns itself off and on consistently and rapidly. This provides constant quality imaging regardless of dynamic and sudden ambient conditions. It also helps to preserve the life of the tube making it last longer since the strain of high illumination levels are reduced.

Put these two technologies together and you have a Gen 3 scope that provides the best imaging quality possible from night vision. It will last longer over its lifetime of use and can perform in various environments for optimal performance.

Scope Features

Its scope features are just as important as its night vision performance. After all, what’s the point of seeing in the dark with a scope if you can’t shoot accurately? The Bering Optics scope is deadly precise. It has ¼ MOA adjustments, 69 MOA windage and elevation adjustment travel, and is ideal for mid-range and long-range shooting.

The D-790 features a mil-dot reticle with either red or yellow illumination. With 6x fixed magnification, your holdovers consistently accurate.

You have guaranteed zero retention with medium caliber weapons, but it can also be used with higher calibers up to .50 cal.

Long-Range Detection

There are some who claim that the D-790 can acquire detection ranges up to 2000 yards. With a full moon, we’re sure it’s possible. But with only a quarter moonlight, it can provide detection of a 6’ target at 925 yards. With cloud coverage, detection drops to 600 yards.

You can expect up to 580-yard recognition ranges in quarter moonlight and 440-yard recognition under cloud coverage. This is excellent performance and long-range detection that only top Gen 3+ scopes can provide.

Nitrogen Refillable

The scope is not only waterproof, it’s also fogproof. The scope has been nitrogen-purged to protect the optics and tube from internal fogging. It also helps to prevent the growth of mold and other contaminants from ruining the scope and ultimately performance. However, not all scopes stay nitrogen-purged forever.

In this case, the D-790 is made to be refillable with nitrogen gas when the need arises. There is a specially designed valve on the scope and a nitrogen kit that can be purchased separately. This will be a new feature to most, and it most certainly is a feature that sets it apart from its competition.

The D-790 is no small scope. It has a large aperture, is 12” long, and it weighs almost 3 lbs. There’s a price to pay for a large aperture that gathers a lot of light and that price is weight.

It shouldn’t be a problem for those who are expecting to have a heavy rig that will be set up on rests. This can be essential for long-range precision, and with the type of long-range detection the D-790 can provide, it may be perfect for your needs.

Popular Questions

How Recoil Resistant is the Bering Optics D-790 6x Gen 3+ Scope?

There has been a lot of improvement in IITs that lack an ion barrier film. To prove this point, the D-790 is far from fragile and is guaranteed to hold zero on medium caliber rifles. It can be mounted to heavier and larger rigs up to .50 cal.

What Type of Batteries does the Bering Optics D-790 Use?

The D-790 takes 2x conventional AA batteries. The first set are included in the box. The AA battery type is often preferred for its ease of availability. They can provide up to 120 hours of operation but will be affected by climate, user settings, brand quality, etc.

What Accessories are Included with the D-790 Gen 3+ Unfilmed/Autogated Scope?

The D-790W scope comes with a standard Weaver MIL-STD-1913 mount, protective carry pouch, photo adapter, objective lens cap, batteries, and user manual.

Are Bering Optics Scopes Made in the USA?

What is the Warranty on the Gen 3+ D-790 Night Vision Scope?

Bering Optics provides a limited 3-year warranty on the Gen 3+ image intensifier tube.


Price is usually the final factor in determining whether a scope is bought or not. There’s no doubt that the D-790 is an expensive option, but it’s one of those high-end scopes that is actually worth buying.

If you need life-changing results from your night vision gear, you must seek out gear that can provide life-changing results. That would be Gen 3 and higher.

The Bering Optics D-790 is not only a top-shelf product for the brand, but it’s top-shelf product for the night vision industry.

It doesn’t need exaggeration to sell itself. It performs exactly as advertised and its high-performance sells itself.
