Budget Thermal Scopes Buying Guide

budget thermal scope

Before buying a thermal scope, you need to assess your needs. Not all hunters have similar needs, and hence not every thermal scope suits everyone. To get the most suited thermal scope for your use, you should consider the following things.

Working Conditions

The first thing to consider is the conditions in which you would visit the field. If you prefer going out in the middle of the night when there’s complete darkness, it is best to invest in a scope with a sensitive sensor.

The 384x288 is a good start as it can detect thermal signatures and present visuals even in complete darkness. Those who prefer to hunt during the day can invest in a sensor that has good heat detection but needs light to function properly.

Weather conditions also play an important role in determining the functioning of your scope. If you hunt in areas where rainfall is frequent, you cannot work with a rifle scope that is sensitive to water.

Similarly, invest in processors and sensors that can function in the presence of smoke and fog for enhanced usability.

Weight of Your Gear

Hunters often carry a lot of gear with them, especially if they plan on spending more than 24 hours out in the field. Some even carry more than one rifle. In such cases, the weight of the gear becomes quite heavy and difficult to bear.

The weight of the thermal scopes also varies. You can find scopes ranging from 1 pound to up to 15 pounds. Before buying a scope, make sure it is suitable enough for you to carry.

If you don’t mind carrying some additional weight, you can invest in heavier models; however, for beginners, it is best to go for a lightweight option. Lightweight models are easier to handle.

Expertise Level

Thermal scopes are easy-to-use and easy-to-comprehend optic devices. Still, some models benefit professionals more than they do beginners. Therefore, it is crucial to ensure that the scope you buy matches your expertise level.

Easy mounting, illuminated reticle, and quick zeroing are features appreciated by all levels of users. However, there are additional features like ballistics control, built-in rangefinder, rifle profiles, etc., that truly bring the convenience of use for beginners.

Such features eliminate the need to carry additional gear such as a separate rangefinder and increase the accuracy of shots for learners.

Why Should You Choose a Budget Thermal Scope Over an Expensive One?

best budget thermal scope

People generally think that a budget thermal scope lacks quality and performance. This is not true.

After some market research, you can find options that perform well and, at the same time, are pocket-friendly. All of our discussed options are available under $2,000 and carry the necessary features of a good-quality thermal scope.

There is no difference in the working principles of a budget thermal scope and a high-priced thermal scope.

You should choose a budget-friendly scope, especially if you are a beginner. Hunting is a rough sport that involves spending hours in the field. People new to using thermal scopes might not be able to take very good care of the first model they buy.

Therefore, to become accustomed to the working and maintenance a thermal scope requires, it is best to practice with a budget thermal scope.

Thermal scopes take quite some operational beating when used under harsh weather conditions like rain and snow. If you want to protect your high-end thermal scopes from the possible damages of harsh weather or a tough field, you should buy a budget thermal scope.

When the weather is not favorable, you can use a cheaper thermal scope rather than putting the higher-end scope at the risk of damage.

Lastly, if you have an old-fashioned rifle, pairing it with a high-end thermal scope won’t yield much benefit. It would be unwise to buy an expensive thermal scope without getting to use it to its full potential.

Therefore, for older ammunition, it is advised to buy a budget thermal scope and upgrade to a higher-end one when you invest in a newer rifle.

Even though budget thermal riflescopes are much more affordable, they still carry plenty of additional features. As seen above, all our picks have additional features like ballistics control, robust sensors, video recording, etc.

What to Look for When Buying a Budget Thermal Scope

A few basic features make or break a good budget thermal scope. They also determine the suitability of the scope for different needs. Below we take a look at these features so that you know what to look for when buying a budget thermal scope.

The Resolutions

You need to consider two different resolutions in a thermal scope. One of these is the resolution of the sensor, and the other is the resolution of the scope lens.

The resolution of the sensor determines how well the scope would be able to detect heat signature. Meanwhile, the resolution of the lens is concerned with the overall clarity of the image.

Ideally, the resolution of the scope should be higher than the resolution of the sensor for a clearer and precise image. Most thermal scopes do have a higher scope resolution.

A sensor resolution of 384x288 is quite good in budget thermal scopes. The clearest HD quality video recording resolution is 1080p and is supported by most thermal scopes.

Magnification Power

budget thermal scope

To zoom in on objects from afar, the magnification power of the scope plays a huge role. It determines the extent to which you can zoom or magnify the image. Magnification power is measured in ‘times,’ which is represented by an x.

Low or close-range scopes have a magnification power of around 2x-4x, whereas medium-range scopes feature a magnification power of 4x-6x. 8x or above magnification is available in long-range rifle scopes.

Another thing concerning the magnification power is the focus. Your scope should be able to magnify the field of view without losing the focus point. A stepped magnification control works best as it does not require the user to take their eyes off the target when adjusting the magnification.

Detection Range

Often overlooked, the detection range is a very important feature that determines your success on the hunting field. It determines the distance to which the scope can see clearly.

It can go as high as 4,000 yards in high-end long-distance scopes; however, the value is quite limited in budget thermal scopes. Usually, a detection range of 1,000 yards is available in budget thermal scopes.

However, when paired with the right rifle, the magnification and detection range work together to provide a long-distance view.

Refresh Rate

The refresh rate determines how quickly the image you see is processed. A slow refresh rate would take longer to process and display the image. This might result in delaying the information output.

Therefore, the faster the refresh rate, the better. In budget thermal scopes, a refresh rate of around 50Hz works well.

Reticle Pattern

budget thermal scope

The crosshair or dot reticle patterns are a user’s personal preference. Both these reticle types are available in budget thermal scopes. The two types are the most common; however, many other types of reticle patterns are seen in thermal scopes.

Generally, crosshair reticles provide greater ease of use during nighttime. The four crosshairs make it easier to find a target spot on the prey. The dot reticle increases accuracy and provides a pinpoint reference for shooting the target.


Thermal scopes are made up of many different parts. These parts can malfunction, and without a warranty, your investment in the scope is lost. Therefore, it is always advisable to purchase warranty-supported thermal scopes.

The warranties available depend upon the sellers and manufacturers. You can find thermal scopes with a warranty on selective parts or the whole product.

Ideally, you should buy a thermal scope with a warranty covering all of its parts; however, if a longer warranty for the main parts is available, go for that.

Battery Life

Arguably one of the most important features in a thermal scope is its battery life. The run time of the battery determines how much time you would spend on the field. Hunters who plan day-long or weekend trips should invest in a thermal scope with a battery life of at least 15 hours.

Another useful tip is to buy extra batteries so that you can replace exhausted batteries with new ones for an uninterrupted hunting experience. Similarly, packing a battery adapter that is connectable to the batteries can also help them recharge quickly on the go.

Video and Audio Recording

Most modern thermal scopes support audio and video recording. Some even allow live streaming and viewing the video on smart devices. For hunters who want to record their trip for viewing later, this feature is quite useful. Built-in recording saves the trouble of carrying additional gear.

If you want to record a video every time you fire your rifle, you should get thermal scopes that come with recoil-activated video recording. Make sure that the SD card used to store this media is securely placed in its slot.

Using large-storage SD cards saves the trouble of buying new SD cards frequently or emptying the SD card after every trip. A 64GB SD card is a popular choice in this regard.

Mounting Rail

The type of mounting rail affects the speed as it determines how quickly you install the scope on a rifle. The right choice of mounting rail is especially important for those who want to use one thermal scope on multiple rifles.

Switching the scope between rifles should be done quickly and efficiently. Hence, it is important to get a mounting rail that is easy to remove and install quickly. A Picatinny or Weaver mounting rail is ideal in this regard.

Limitations of Using a Budget Thermal Scope

best budget thermal scope

Budget thermal scopes make night-time hunting quite easy at an affordable price. They make the experience available to greater masses. However, they have limited capacity. Below we discuss the limitations of using a budget thermal scope.

Limited detection range

Budget thermal scopes do not have a long detection range. Usually, the range falls under a thousand yards. While this is enough for most short to medium-range uses, it might pose limitations for long-range use.

Inability to look through glass

Thermal scopes cannot detect heat signatures through the glass. Therefore, the hunter needs to be in an open area to use them, and no glass should block the view.

Final Verdict: Which is the Best Budget Thermal Scope and Why

We believe that the ATN ThOR-HD 384 is the best budget thermal scope from amongst our discussed options. For a very good price, you get high resolutions, a ballistics calculator, and a rangefinder. The scope also supports all sorts of media recording, making it a great purchase.
