In the world of advanced thermal optics, the ATN Thor LT Thermal Rifle Scope came as a budget-friendly model for beginners and entry-level shooters.

However, that does not mean serious tactical shooters and advanced hunters cannot benefit from using it. Check out the detailed review here.

Yes, it lacks some noteworthy advanced features, but the quality and performance sets it in line with some of the best thermal scopes currently available.

It is equipped with a 1280 × 720p HD display and a 160 × 120p thermal sensor. Both of these allow you to focus on the smallest detail with awesome clarity.

best thermal scope under

The TS25-384 model in AGM’s Secutor range is a compact and lightweight unit designed for close-range work.

Although it lacks the bells and whistles of higher-end thermal scopes, it does not need them to attract buyers if truth be told.

With its numerous color palettes, zeroing profiles, and stadia metric rangefinder, it can outperform almost any thermal scope, especially when it is used within its capabilities.

When we say it lacks digital features. We are not talking about the essential ones. Instead, they are extras that most experts consider unnecessary. But when it comes to essential features, this Secutor does not disappoint.

The device is a standalone scope. You may think otherwise because of its size and weight, but let us tell you that you can comfortably use it without the aid of another optic or device.

It has multiple reticle options for better aiming points, supports both optical and digital zoom, and a simple zeroing process for five different profiles with five zeros for each.

AGM is known for producing some of the best mounts in the world. They are designed to be robust and can fit well in both Picatinny and Weaver rails.

Their Secutor TS25-384 comes with a dual-lever mount that features a quick-release design. It holds the scope securely to the rail and also allows for quick installation and removal.

Thermal Scopes Under $4000: Buying Guide

best thermal scope under 4000

Thermal scopes are something you should not buy instinctively. There are actually tons of models available in the market, each designed for specific applications.

For example, thermal scopes for competitive sports are great at capturing the target in motion. While for hunting purposes, there are thermal scopes that provide hunters with an edge.

So, it’s important you do your research before heading out because the conflicting opinions and information are quite overwhelming and are too much to process.

That’s why we have compiled a comprehensive buying guide to help you pick up a good thermal scope under $4000. Have a look:

Brand

A thermal scope is a hefty investment, so you really can’t throw your money without proper research. When you take the time out to look up some reliable brands, the following names will certainly pop up:

ATN

ATN is a top name when it comes to thermal scopes. It has been around for a while and has managed to make its mark in the highly competitive market.

ATN Thermal scopes are advanced pieces of equipment that are useful for competitive and hunting applications.

FLIR

FLIR is undoubtedly a leader in designing and developing thermal equipment. Its product line-up also includes some quality night vision equipment.

It has a diverse portfolio of both technologies. This is why its products are highly sought-after by the government, commercial, and industrial sectors.

Pulsar

Pulsar gained immense popularity for its Night Optic and Electro-Optic devices that are widely used for hunting and animal research applications.

Its thermal imaging products are also top of the line. The thermal scopes it manufactures are specifically directed for both civilian and military markets.

Trijicon

Trijicon is the producer of high-end thermal scopes. This brand is well-known for its premium thermal and regular riflescopes. All its products are very durable, high quality, and long-lasting.

AGM

AGM is another notable brand that specializes in state-of-the-art night vision and thermal imaging systems. Law enforcement agencies and hunting and wildlife enthusiasts are both drawn towards its superior products.

The brand’s product line-up includes some of the best clip-on thermal scopes. So, if you want a quality product with reliable performance, go for AGM thermal scopes.

Price

Thermal scopes are undoubtedly more expensive than digital night vision scopes. You’ll be hard-pressed to find a quality product for less than a few grand. And the more features you want, the higher the price will go.

Some manufacturers have down-priced their thermal scopes so you can find a good product at an affordable price. If you want a premium feature-rich unit, know that it will set you back a significant amount.

You can also choose to rent one. Check out our guide about renting or owning thermal imaging devices here.

Weight

The weight of a thermal scope is also an important consideration when buying a unit for yourself. A heavier thermal scope is not only difficult to carry, but it is also likely to reduce the balance and accuracy of your rifle. So be sure to weigh your chosen product before you finalize your purchase.

Features to Look at When Buying a Thermal scope

best thermal scope under 4000

As with any accessory you purchase for your firearm, thermal scopes also require plenty of research before you can decide on a certain unit.

Trust us, if you set out without acquiring some prior knowledge, it will be the most stressful purchase you have ever made.

To help you out, we have compiled a list of features that you should look at when buying a thermal scope. Knowing these will help you make a better choice for the thermal scope you will pair with your rifle.

Resolution

The first feature you need to look out for is the resolution. First, you should understand that the resolution of the scope and sensor are two different things.

The resolution of the scope should always be higher than the resolution of the sensor. The more the difference, the precise the image you will get. A thermal sight with the same sensor and scope resolution will not produce a clear image.

Detection Range

The second most important feature to look at when buying a thermal scope is its detection range. This refers to the minimum distance at which you can obtain a clear image of your target.

Some models can produce clear images for distances as long as 4000 yards. But these high-end models carry a hefty price tag.

You can also find some cheaper variations with a detection range of around 1000 yards. It is a great idea to start with a shorter-range scope before moving on to longer-range units. That’s what most professional hunters recommend.

Magnification

Magnification is the thermal scope’s ability to zoom in on your target. Each thermal scope available on the market comes with details and specifications that will tell you about its magnification capabilities.

One thing you should keep in mind is that the scope’s ability to magnify the image directly affects its resolution. The more you zoom in; the clarity of the image might drop.

Refresh Rate

The amount of time a thermal scope takes to refresh its image is called its refresh rate. Since they generate a digitally produced image, there is a slight delay in refreshing the information input they receive into the image you are seeing.

As a general rule of thumb, the higher the refresh rate, the clearer and more accurate image a thermal scope will produce.

Look for a model with a 30 to 60 Hz refresh rate. Remember, the refresh rate tends to drain the battery fast, but you get an accurate and clear image as a result.

Reticle Pattern

In thermal scopes, you get to choose between different reticle patterns. The most preferred types are either a four-line crosshair pattern or a single dot reticle pattern.

While both of these have their merits for the user, you should choose one according to your personal preference.

We believe that crosshair reticles are better for hunting at night, while single dot reticles are great for accuracy and precision.

Lens Diameter

The lenses used in constructing a thermal scope play a significant role in what it displays. If you want a wide field of vision, go for a scope with a larger lens diameter.

The wider the diameter of the lens, the more area it will capture. So if you want to cover a larger area, go for a thermal scope with a larger diameter.

Battery

Perhaps the most basic consideration in any thermal scope is its battery life. An ideal unit should last about eight hours of runtime on a single full charge.

Anything less than that is unacceptable because even a short hunting trip takes about this much time to be successful.

Look for a device with long battery runtime, and take care not to overcharge it as it can greatly reduce its life.

Warranty

There is no doubt that a thermal scope is a hefty investment. Surely, you won’t want to spend such a significant amount without any form of reassurance. Since you will take it with you in challenging circumstances, it has to be sturdy and reliable.

The chances of it getting damaged are huge, so you have to make sure it comes with comprehensive warranty coverage. This is in case your thermal scope malfunctions or fails to deliver what was promised.

Final Verdict: Which is the Best Thermal Scope Under $4000 and Why

After carefully testing and inspecting each unit, we declare ATN Thor 4 Thermal Rifle Scope as our top pick for its reliable performance and long battery life.

Pulsar Thermion Thermal Riflescope XM50 closely follows it with its long detection range and high magnification.

Lastly, Pulsar Core RXQ30V Thermal Rifle Scope is our budget pick for its quality performance and affordable price.
