Searching for the best dual tube NV goggles?
Look no further!
Whether you need gear for a hunting trip, tactical equipment for a shooting competition, or just want to feel like you’re a part of SEAL Team Six, a night vision goggle is an extremely valuable piece of equipment to have in your arsenal.
However, with so many different types available in the market, choosing the right model can be a bit difficult.
To ensure you don’t end up wasting your money, we’ve reviewed some of the best dual tube night vision goggles available today and included a comprehensive buying guide as well.
Let’s dive in!
Should You Buy a Dual Tube NV Goggle?
Dual tube night vision goggles work by amplifying the light that’s invisible to the naked eye. These optic devices usually don’t have magnification, so the visible image distance is similar to what you would be able to see with your unaided eyes.
Since dual tube models cover both eyes, they give you better depth perception than a camera or a unit with only a single eyepiece.
To put it simply, NVGs artificially improve your own natural night vision. Dual tube devices provide information to both your eyes, making them more suitable for use in 3D environments, and they also make it easier to use reflex sights.
It’s universally agreed that the best option is to shoot with both eyes open, and the same rule is applied to shooting with dual tubes.
When you’re using a pair of single-tube night vision goggles to look through a red dot, it can be a bit difficult to locate the reticle. The light reaching the red dot is reduced, making it hard for you to find your target through the optic.
However, in dual-tube models, both of your eyes are covered, providing you with more accurate information and allowing you to identify the target with the red dot floating over it.

Dual Tube Night Vision Goggles Buying Guide
What are Double Tube Night Vision Goggles – and how do they work?
Dual tube night vision goggles are simply devices that have two image intensifier tubes. They don’t have any magnification and can be head-mounted. The best thing about these optics is that they are extremely easy to use and feel incredibly natural when you’re wearing them.
These units are designed with a photocathode, a light-sensitive surface that converts photons from light into electrons. A photomultiplier (a type of photoelectric cell) then multiplies the electrons and pushes them to a phosphor screen. As the electrons hit the screen, they transform into tiny flashes of light.
Since this increases the number of photons, the screen creates a much brighter and clearer rendition of the original scene.
Dual tube night vision goggles provide ‘stereo vision,’ meaning that each eye perceives its own slightly different picture instead of both eyes sharing the same image.
Like monoculars, these units are great navigation devices that allow you to walk and hunt in the dark. Stereo vision also provides you with better depth perception and improves your navigation ability.
Different Types of Phosphorus Tubes and which one is better
There are two types of phosphorus tubes available today: the traditional green and the newer white phosphor technology. This color difference is because of the phosphor used in the image intensifier tube.
P45 phosphor screens create a black and white image, while P43 results in a green-based picture. Both phosphorus tubes enhance the light that reaches the screen, allowing users to see in low-light conditions.
Traditional models use a P-43 screen output, creating a yellow-green image that has become the trademark view of most Gen 3 night vision devices.
You can also see more shades of green with your naked eye than any other color, and some users have stated that they’re better able to adjust to the dark with green phosphorus tubes.
On the other hand, a P-45 phosphor screen yields an image with a black and white coloration. Some users state that this color enhances overall object recognition and provides a contrast sensitivity equal to the green phosphor.
They also state that it shows a brighter image than green phosphor and reduces eye fatigue, allowing comfortable and continuous use.
Despite the claimed technical advancements, some users still prefer green phosphorus tubes instead of white ones. However, there is no scientific evidence that proves that one phosphor color is better than the other.
If there is a difference in the clarity and resolution, it might be because of the night vision technology itself and not the phosphor color. Since every person’s eyesight is different, your decision ultimately comes down to your preference.
How is Dual Tube Different From Single Tube Night Vision Goggles?
Dual tube units have better depth perception than single tube models because each eye perceives a slightly different picture, allowing for a more precise judgment of distances. This helps you with navigation, whether you’re maneuvering your boat around rocks or hunting in dense undergrowth.
One of the most significant differences between single tube and dual tube night vision is their cost. Dual tube models are almost twice as expensive as single tube ones. They’re also heavier and less versatile, as both your eyes are covered with the night vision device.
One of your eyes is uncovered in single tube goggles, so it’s easier for you to read lighting conditions. However, since both of your eyes are behind the night vision in dual-tube models, it’s difficult to see colors while using them.
For instance, if you’re driving with dual-tube night vision, you won’t be able to identify the color of the lights, but you can see them with a naked eye.
Some models are incredibly rigid, so you have to flip the entire device up and out of the way if you want unaided vision. However, the latest dual tube night vision goggles, like PVS-31s, come with the flexibility of rotating one or both tubes out of the way.
What to look for in Dual Tube Night Vision Goggles
Dual tube night vision goggles usually cost a lot of money. To ensure you find a model that best suits your needs, we’ve listed some of the features you should consider before finalizing your decision:
Night vision goggles are a generational system and are divided into Gen 1, Gen 2, and Gen 3.
Gen 1 units are the most inexpensive, with a 75-yard viewing range and low resolution.
Gen 2 devices are neither too costly nor too cheap. With a 200-yard visual range, longer battery life, and light amplification, these enhanced optics are ideal for shooting, driving, and hunting.
Gen 3 models are the costliest but are similar to tactical night vision optics used by the US military special forces. They offer a 300-yard viewing range and have the best battery life.
Most people use night vision goggles for long periods, so it’s important that you consider the weight. This is particularly true for models that can be mounted on a helmet or worn on your head.
Heavier units can result in neck strain, so it’s better to look for night vision goggles that weigh less than 20 pounds. Tactical units usually have more lenses, so they have a higher weight by default.
If you’re going to use your night vision goggles for hunting or want a clear line of sight, you need to consider the size.
It’s better to avoid very large models, as they’ll prevent you from properly using sights on rifles. Also, make sure you consider units that you can retract and move up and out of the way when not in use, so you can use other objects easily and safely.
If you’re planning on using dual tube night vision goggles in extremely dark places, the gain is a key feature.
Gain basically refers to the ability of a pair of goggles to compensate for the varying light levels at night optically. A unit with better gain offers a better viewing experience and a crisper, clearer, and more detailed picture, even in low light conditions.
This feature is particularly useful in areas where the light conditions change constantly.
Dual tube night vision goggles are generally designed for active or outdoor use. But it’s important to remember that cheaper units usually perform poorly.
It’s better to go for a model with a durable aluminum body instead of a plastic one, as it will last a long time. Similarly, opt for glass lenses instead of other cheaper lens alternatives.
If you’re worried about the weight of your dual tube night vision goggles, select a unit with an integral illuminator. Since this is a separate light source, you’ll be able to read the text in dark areas, even when you’re not using the goggles.
Whether you’re planning a hunt in the marshlands or camping in wet and muddy areas, it’s crucial to consider the weatherproof rating of your night vision goggles. If you’re going to work in places with frequent bad weather, it’s better to upgrade to a costlier water-resistant model.
