Thermal Vs. Night Vision Rifle Scope – Which one to choose for night hunting

Worldwide, the choice between night vision rifle scopes Vs. thermal rifle scopes are always a popular topic among recreational shooters and hunters. Thermal imaging scope is a more expensive technology compared to night vision devices. 

Thermal Vs. Night Vision Rifle Scope

Wondering about the difference between thermal rifles and night vision scopes? You have found the right place! This article provides a comparative analysis of the technology behind both rifle scopes and will help you make a favorable decision. But first, let’s discuss their functions!

How Does the Night Vision Device Work?

The night vision binocular first came about in WWII, introduced by the German army in 1939, and has witnessed tremendous technological advancement since then. These advancements are rated in Gen 1, 2, or 3 categories.

As the name suggests, the top rated night vision optic enables users to see in the dark. However, it is worth noting that it relies upon ambient light from the surroundings to generate an image. It does not function in complete darkness or daylight. It functions in low light conditions by amplifying ambient light in the dark. Night vision scope can use IR Illuminator to generate light In the absence of natural light. But you don’t have to worry: They are not visible light to the naked eyes, hence cannot scare away your target.

Night vision devices let you see images up to a thousand yards away, which would have been impossible to do with your naked eyes. While both have similar technology, the functionality depends on your night vision device.

The traditional night vision binoculars work by taking ambient light from the objective lens. At this stage, it is called photons. The photons are converted into electrons and amplified in the image intensifier tube; this then passes through a screen inside the scope covered in phosphor and is converted back into the light to create an object or image for the user. This image typically displays in green and black.

While the digital night vision rifle scope is the more advanced technology of the night vision scope, this electronically enhanced digital imaging system grants the viewer superior image detail and a more detailed view compared to traditional night vision devices. It works by capturing visible light through its objective lens, which then gets processed with a coupler device that transmits an image onto the LCD screen in a black and white representation.

One of the advantages of the digital night vision rifle scope is precise imaging. Unlike traditional night vision devices, you can also use them during the daytime. Now, let’s consider thermal riflescopes.

How Does Thermal Riflescope Work?

Thermal rifle scope differs from night vision devices that only operate in the dark, relying on ambient light. The more advanced thermal binoculars can function effectively day and night in most conditions except for the extreme cold. 

A thermal riflescope works by picking up the heat signatures from its object and comparing them to each other. All objects around send some infrared radiation. This radiation is picked by the thermal imaging scopes, which transform into thermal images on the screen. Again, unlike night vision devices, the best thermal scope can spot a camouflaged target or targets behind a barrier. 

While night vision optics portray its target in a higher resolution, almost rendering an actual image, the thermal images use various colors to depict their target, from black and white to varying shades of red and blue, illustrating heat from an animal or human. Many hunters favor using the thermal rifle scope as it enables them to see through tall grass, fogs, vegetation, storms, harsh weather (except extreme cold), and obstacles that could act as barriers. In addition, thermal binocular covers more distance than night vision binoculars.

So,  what are the pros and cons of thermal imaging and night vision scope? 

  • Pricing

Pricing is one of the most significant factors most hunters consider in choosing a scope. It is no surprise that thermal images being the newer and more advanced scope, are costlier. Though most favor thermal rifle scope over night vision devices, not many hunters can afford such a high price for quality best thermal scope. 

Night vision optic has been around for a while before thermal optic. It is available in various generations and models that would suit most users’ requirements and are budget-friendly.

  • Imaging 

Night vision devices offer more vivid image quality with better details, especially when you want identification of your mark, such as facial identification. Night vision optic has an edge over thermal images here, as the latter, though an excellent game detector, portrays its image representation in blobs of color. Another positive advantage of a night vision device is its capability to function in extreme cold and heat, contrary to thermal scope. 

On the other hand, thermal images are a master at detecting games in most conditions. It is more efficient in spotting targets behind barriers, camouflage, fog, smoke, vegetation, storms, fire, in still motion, and covering a longer distance. A night vision device may not be able to function under such circumstances, even to spot stationary targets.

  • Daylight 

A more detailed image is one advantage of night vision binoculars over thermal binoculars. The former are primarily ineffective in daylight, bright light conditions could damage their internal components, and their function is exclusively for nighttime use. The thermal monocular does not require such conditions to function, as it does not rely on minimal available light to operate. Specific new generation high-end night vision scopes can now perform in daylight use, but the thermal scope remains more compatible to function in dual-day use.

  • Durability

The consensus among hunters is that though both devices are reliable and durable, the night vision scope is more enduring. The night vision rifle further edges the thermal riflescope on longer battery life and is lighter to carry. 

Both devices have critical components that need looking out for to ensure their longevity, as both can withstand .30 caliber recoil. The standard for caring for them is not leaving the battery inside for a long time. In addition, cover optics with a glass filter whenever possible to avoid dirt and scratches, put lens covers on when not in use, and handle with care. 

Thermal Rifle Scope Vs. Night Scope Considerations 

Other potential factors can help you determine your choice of rifle optics, as the debate between thermal rifle scope vs night vision rifle scope ultimately comes down to them.

Your purpose, the hunting environment, and shooting conditions are vital considerations. If your concern is for personal security purposes, tactical purposes, or recreational shooting, thermal imaging is advisable for its twenty-four-hour reliability.

For hunting purposes, you must consider what environment you will be hunting in and the shooting conditions. The thermal scope is your best option for dialing in and shooting from extreme distances as it has more capacity to cover longer distances. Thermal monoculars are also more valuable if you hunt in fog, tall grass, or thick bush because they can detect and track a game from behind an obstacle, unlike night vision technology.

Nonetheless, night vision technology is a more bankable option if your hunting happens in places with colder conditions. Thermal monoculars’ ability to detect heat signatures declines under such weather. There is also the issue of regulations when deciding on the thermal rifle scope and night vision scope.

Some countries prohibit using thermal imaging devices for hunting some species. So if hunting is your purpose for deciding on a thermal imaging device, it will be wise first to research your local regulations. It is imperative to do your research on the devices available to you, know what to expect, and discover which best suits your needs. You can read a more details guide about thermal scope from Accurate Ordnance.

Final Thoughts

Whichever side of the debate you support, you’ll agree that thermal vision Vs. night vision has massively changed the hunting experience for the better. There is no question that both optics are luxury on a night hunting trip. Remember,  the thermal optics can be used to spot and track the heat of the desired game, even from an extreme distance, while you can use the night vision scope for identification. 

Besides being luxurious devices, they are essential for tactical setups and personal security. They also come in handy for nocturnal varmint and pest control.
