The thermal imagers were the first time met by the broad audience while watching the sci-fi action thriller Predator with Schwarzenegger. By the time, it was already clear to many that the hide-and-seek game would be much less exciting in the future.

As you probably guess, the night vision devices were developed for military purposes.  If we disregard the military and Law Enforcement purposes, then we are entering the world of low-light hunting scenarios, very well known to varmint and hog hunters.

Just a decade ago, one of the earliest challenges that hog hunter encounter was the selection of their first night-vision device (NVD). These gadgets intensify the available light thousands of times so that targets can be seen at night.

However, these days, the term “night vision” has added meaning, and outdoorsmen who are looking for a scope that will perform in low-light conditions have a choice of a night-vision device or a thermal-imaging device.

Guide To Buying Thermal Scope

If you are searching for the best thermal scope for the money you need to find functional scope and one that should be able to work perfectly well regardless of the environmental conditions and weather situations.

Before you decide on a particular model, you need to know what to look for when buying a thermal rifle scope. Here are some aspects to consider while going for the best of thermal vision scopes.

First, similar to the night vision, there are two types of thermal imaging systems on the market today.  Thermal scopes are available in clip-on and standard, standalone configuration. A dedicated rifle scope is a thermal sight featuring the reticle and all adjustments in its housing in which the system is self-sustaining.

An alternative is the “clip-on” thermal device that mounts in front of a standard daytime riflescope. With mounted clips-on thermal sighting scope, you will be using the reticle, magnification and adjustment of the day scope.  Obviously, the clip-on thermal scope is cheaper than standard thermal scopes, but also it is more flexible as it can be used hands-free like a spotter.

The second classification is based on two operational systems; the near-zero cooled and uncooled ones.

Most thermal imaging devices are designed as an un-cooled thermal imaging system, which is sturdy and cheaper, then but not as sensitive as the cooled thermal scopes.

For the average civilian user, it is essential to know that near-zero cooled or cryogenically cooled thermal imaging systems offers improved sensitivity over non-cooled devices. Still, they are more complex, more susceptible to rough handling and seems to be more costly than the former type.

Since a lot of thermal imaging riflescopes being produced are the un-cooled types, all models from our list belong to that type.


The sensor resolution of your rifle thermal scope is the most important consideration when buying a thermal imaging riflescope. A high-resolution image that appears on display should possess a crisp and precise definition of an object. With proper resolution, you will able to see not only a patch of color but the detailed shape of an animal, where you must be able to distinguish the various parts of an animal.

Contrary to some beliefs, it is far more important than the magnification, and you should purchase a thermal with as high a resolution as you can afford. Usually, an average to high-quality thermal scope should have a 640×480 screen resolution.


Thermal scopes can cover considerably greater distances compared to the daytime scope or night vision devices. Actually, the sensitivity of the thermal detector can easily detect the objects at length longer than 1,000 yards.  You will need the detection range that is longer than your hunting distance because the extra range will allow you to scout your games that are hundreds of yards away and watch as your target approach.

Along with high-end scopes having the range over 1,000 yards, there are more modest scopes with a range of 300-500 yards, but you should know that shooting beyond a few hundred yards at night is not a safe practice.


Like with the traditional daytime scope, you should opt for thermals with better optical magnification instead of digital zoom. You will get the best results combining both of these zooms. The majority of the scope top out at magnification power around 15x, but for reasonably night shots at 50-200 yards, a magnifying power of 5 times would be enough.

Refresh Rate

The refresh rate is the frequency the image will be changed per second. A higher the refresh rate means a smoother and more lifelike image when tracking the target. To avoid issues with blurriness, we recommend that you opt for a refresh rate above 30 hertz, and preferably 60Hz per second.


As opposed to the conventional daytime optics, thermal sighting scopes may offer quite a number of extras and add-ons implemented into their design. However, you shouldn’t ignore the general quality of the thermal scope for the add-ons, which are just a sideshow.

You can get thermal scopes with a meter to gauge the rifle inclination and the Geographic Positioning System, or a rangefinder. It's even very common to find thermal scopes that have WiFi which can broadcast straight-up to your smartphone or more advanced scopes also have ballistic matching technology with app support.

Who Makes The Best Thermal Scope - The Brand Worth For?

resolution thermal image

Few strong brands are offering a range of quality thermal imagers widely used by military and law enforcement personnel. Still, their products can be often seen in the hands of civilians and other commercial consumers.

FLIR Systems

One of the more prominent names in the industry and a leader in infrared technology is a Forward-Looking Infrared system (FLIR). FLIR Systems are producers of a special variant of infrared thermal sensors that the majority of thermal optics uses.

The FLIR Systems are responsible for many innovative products and technologies that are used today, with most of their products being used for industrial purposes. Although the FLIR manufactures thermal imagers for a myriad of sectors including military-grade thermal imagers, their very expensive thermal weapon sights and monoculars are often used for hunting, animal research observation and outdoor activities.


Another great company offering the peak of performance in the thermal vision industry is American Technologies Network, Corp. (ATN) with headquarters in San Francisco, CA. This manufacturer of superb night vision optics and thermal imaging gear is one of the leading companies in the sector of the thermal technology offering thermal weapon scopes, monoculars and goggles.

ATN features a professional line of thermal vision, which is a fantastic choice for higher-end uses, but luckily most of their popular models come within mid-price range.

Pulsar Systems

Pulsar by Yukon Advanced Optics is on par with the other two brands in most respects since it is built on a Mil-Spec platform. Pulsar is a renowned brand with a long reputation for producing night vision scopes, but from 2012 they have turned their hands to making thermal imaging devices with great success. Pulsar thermal scopes come with an affordable price making them a favorite of many hunters and wildlife enthusiasts.

Armasight Thermal Imaging

Armasight makes good products that are not as popular as FLIR or ATN, but they are likely to become so.  Besides night vision optics, Armasight Company is offering thermal Imaging products like scopes, goggles and monoculars with the greatest price-to-performance ratio.

While Armasight focuses on supporting military and law enforcement professionals, they also produce a wide range of high-quality thermal imaging devices. Actually, the Armasight series of thermal optics are using the thermal imaging cores made by FLIR.

Thermal Scope vs Night Vision Scope vs Infrared vs FLIR

As mentioned earlier, a night-vision scope requires some ambient light or an IR illuminator to function to the optimum. After more than 70 years of existence, the night vision optics with its latest 3rd or 4th Generation units have reached the pinnacle of its development exemplifying the gold standard in the current technology.

The night vision devices require available light to amplify, but even using starlight the standard night vision scopes will produce more detailed images than those from the thermal scopes. Additionally, the night vision scopes are cheaper and more rugged than thermals.

Night-vision technology, on the other hand, has some limitations regarding external factors like weather or physical obstacles. Іnfrаrеd іmаgеrѕ оr саmеrаѕ cannot see an object through the thick bush, while the dust, smoke or fogs are obscuring the visibility, making NV device almost useless.

Contrary to night vision optics, a thermal scope needs no light to see, because the thermal imagers allow the shooter to see objects in darkness via the heat that it radiates. The thermal devices dіѕрlау tеmреrаturе іnfоrmаtіоn processed by the internal computer in the form of a thermogram.

FLIR or Forward-Looking Infrared sensors are the systems that the majority of thermal night vision rifle scopes use.  While the conventional infrared riflescopes are developed tо рісk uр раrt оf thе lіght ѕресtrum іn thе 700-1,000nm range, top-rated thermal scopes would be аblе tо work іn thе 8,000-15,000nm раrt оf thе ѕресtrum.

How To Sight In a Thermal Scope

Indeed, as an advanced piece of equipment, the thermal scopes are complicated and they are a far cry from the standard daytime riflescopes. Although very different, the thermal scopes request somewhat similar approach to the sighting process.

Being an optoelectronic device, thermal imagers haven’t turrets to make adjustments whereas the reticle is digital. That said, you would make adjustments of reticle, windage and elevation by pressing buttons.

However, the first step request from you to carefully read your manual, to understand how your thermal scope functions and how exactly you’ll be making adjustments. It will save your money and time at the range, definitely.

Now, one critical tip, you need unique reactive targets to zero in a thermal scope. These targets glow under a thermal optic, but they are pricey. Alternatively, you may use a pack of hand warmers from Walmart fixed with aluminum tape to the standard paper target or black “Shoot-N-See” adhesive dots. You can also use a small piece of aluminum foil (2" square) stapled to a wide section of plywood or cardboard. You should tilt the whole target just a bit to catch the sun, as it will help a lot.

With properly mounted and secured optics, you will need a stable shooting position such as sandbags, shooting rest or bipod.

For proper zeroing in or sighting most experienced shooters recommends a distance of no more than 50 yards.

Similar to daily scopes, sighting in starts by firing three rounds into the target and measuring the middle shot from the center. After you take a rough measurement of the vertical and horizontal distance to the bull's eye, mark the middle strike with another bit of foil.

Now make corrections in both directions by moving the crosshairs to the second piece of foil - the point of impact and shoot another string of three rounds and observe where the three rounds landed.

You should be nearly bull’s eye. If not correct.  If you are satisfied, fire one more round of three shots and recheck it.

Now, when you get your close-range zero, move back to 100 yards and check your zero with a few shots.

Most hunters usually zeroing their thermal scopes to 100 yards or so which is all you need at night

How Do Thermal Scopes Work

The thermal scopes are easily on the top of the food chain when it comes to night vision optics and they are likely the most advanced equipment you will ever buy for hunting. Most of the processes inside the thermal scope are complicated with too many scientific expressions and phrases, so will try to the describe functioning of thermal-imaging devices (thermals) in a plain and straightforward way.

In fact, this technology uses the third type of infrared light, called thermal IR, which is created by living creatures in the form of thermal radiation. Since the thermal imager consists of detectors and lenses when the invisible thermal IR hit the thermal optic the computer in your device establish a graph of the heat values and converts them into the viewfinder display of the scope. This heat-graph, also known as a thermogram, is projected into the scope's display almost immediately making it looks like it is happening in real-time.

Where night vision amplifies existing light, thermal scopes rely on the heat generated by objects. If there is a temperature difference, the thermal device will measure the difference between the heat given off by a target and the amount of heat in the surrounding area.  In simple words, the thermal scope delivers a visual representation of the infrared energy as anybody temperature is hotter than its cold, dark surroundings.

Frequently Asked Questions

What is the best thermal scope for hunting?

What is the best thermal scope for hunting?

Unfortunately, the best thermal scopes for hunting are not cheap and you cannot afford two or more units for different hunting scenarios, like will you do with traditional daytime scopes. If you want to conquer the night, you should invest in a thermal scope which is the ultimate choice for hunters on feral hogs and predators.

The top tier optics for thermal hunting scope should have a proper magnification appropriate for the range of field that you'll be hunting in because you might have to shoot your prey from a more extended range than usual.

A top-quality thermal scope for hunting needs sufficient detection range ability, to make it more likely for you to find a game to hunt down.

Although the thermal scopes are the best when you need to hunt in the pitch dark, thermal sight equipment can be just as effective and helpful during the day, so you should shift between night and day modes quite seamlessly.

Finally, the thеrmаl іmаgіng рrоduсtѕ intended for the hunting should be able to keep up with a few bumps and falls without breaking or malfunctioning.

What is the best thermal scope for coyote hunting?

Thermal Imaging is the best option for predator hunting because every night time hunter knows that coyotes and similar species can "see" IR light from the night vision scope.

Since the most quality thermal scopes are quite large and heavy, you should look for a most compact and lightweight thermal scope. You need thermal imager with higher resolution to positive identifies coyote at longer ranges. As the typical ranges for night predators hunting are up to 200 yards, you'll want something with at least 4x-6x magnification.

Can you see deer horns with the thermal scope?

The answer is a definite yes. Though the antlers don't carry a large amount of heat, a thermal imager will take a small change in temperature between the antlers and the background. Compared to the night vision, the thermal scope image is not as sharp, so you won't be able to see a lot of details or to determine the size of antlers.

Can thermal scopes be used in daylight?

Since the thermal imaging devices rely on the heat that is radiated from an object and not on any light levels, they can be used equally well day and night.

Even though a thermal scope is mainly designed as an overnight vision, it is compatible with both the daytime and nighttime use. If temperatures are hotter than the object you are observing, most thermal scopes will pick differences in heat rather than the hottest object out there. However, it will work better at night because of the pronounced variation between the temperature of the background environment and that of the target.

Can thermal scopes see through walls?

No, thermal scopes cannot see through the walls of glass, nor even can identify people through leaves and the branches of trees.

This is movie-land nonsense because the walls are generally thick enough and insulated to block any infrared radiation from the other side.

How long does a thermal scope last?

The thermal scopes and cameras that can now be bought easily by the average civilian shooter may last for years if properly maintained. As with many optoelectronic devices, it mainly depends on the brand, on how often you use it, and how well you maintain your scope.  While for most consumer class thermal scopes, you can reasonably expect to last as long as 5 to 8 years, the military-grade thermal weapon sights are using thermal cores made by FLIR who offers a 10-year warranty.

What's the difference between thermal and infrared?

Thermal-imaging devices look at the invisible heat produced by living things and translate that into a shaded image, which is presented to the viewer. This type of infrared light, in this case, is called a thermal IR.

In contrast to the Near IR and MID IR light, the Thermal IR is the farthest on the IR spectrum from visible light. A digital and classic night vision systems rely on the shorter wavelengths type of IR that travel slower compared to the invisible thermal IR light.

As for the advantages, Thermal scopes shows living targets better at the further range and can be used in daylight. On the other hand, night vision devices are far more affordable and available and under suitable light show terrain better.


Thermal іmаgіng рrоduсtѕ are not widespread like standard night vision devices not only they are a newer technology, but because of their price. Some of the best thermal scopes can cost you some $19,000, but with a growing offer, you can expect to pay less than a $5,000 bill to get a decent thermal scope.

Definitely, purchasing a thermal scope is a significant investment for most civilians, so you should be cautious of cheap thermal scope and those that are unproven.
