The ATN ThOR 4 384 1.25-5x Thermal Smart HD Rifle Scope is packed full of features typically found on thermal scopes costing much more. The 384 resolution provides good image clarity. Three color palettes (Black Hot, White Hot, and Color) make this thermal scope useful day or night in many poor weather or environmental conditions.

It is fairly easy to use with a spin-to-zoom wheel and tactile buttons so you can operate it without taking your eyes off the target. Mounting on most rails is simple with the included 30mm rings giving you 90mm eye relief. An L-shape ring is also included if you need extra eye relief for certain setups.

The most useful features for hunting are the ballistic calculator, rangefinder, and programmable mil dot reticle which all work together to help you get the shot. 

This Wi-Fi enabled scope allows you to simultaneously record high resolution video and live stream using your phone or tablet. When a shot is fired and your scope experiences recoil, Recoil Activated Video (RAV) automatically records video prior to the shot being taken and some time after. This feature isn’t perfect as some air guns may not provide enough recoil for RAV to be activated.

Bluetooth allows other ATN smart accessories to communicate with your scope, furthering its usefulness. This pick has the longest battery life of all of the options we tested. On the other hand, it’s also the largest, so expect a scope loaded with all of these features to add a bit of heft.

Eleven temperature imaging palettes make this versatile enough to use day or night in nearly any weather or environmental conditions. This waterproof, shockproof thermal imaging scope was made to withstand harsh conditions and even prevents internal fogging.

The control panel is intuitive and user friendly making this one of the easiest scopes to operate. A remote control allows you to make adjustments with little movement off your weapon. Information on the profile, palette, reticle, etc. is continuously displayed so you don’t have to click through settings. This was a game changer when making split second decisions in the field. The most recently selected reticle option is even saved for the next time you use it. Set up is simple and multiple profiles can be saved for use with different rifles and cartridges.

The adjustable, quick-release mount uses a lever-cam clamping device that fits any Picatinny, MIL-STD-1913, or Weaver weapon rail.  Plus, an additional Picatinny/Weaver side rail allows for the installation of optional accessories like an HD Video Recorder, Wi-Fi, extended battery packs, etc. Depending on how you plan to use the Secutor, an extended battery pack may be a good idea, as the battery life is only 5 hours.

A stadiametric rangefinder and recoil resistance rounds out the features of this solid choice. Even with all of the features, it is relatively lightweight at just 1.4 lb. Although it lacks the video recording features of our top pick, the quality of this option makes it a good choice if you have the budget for it.

Things to Consider

things to consider

Pricing 

Thermal rifle scopes have a broad price range starting around $1,000 and going upwards of $10,000. Resolution is a primary driver of price point, especially in lower priced models. Even if your budget is tight, we don’t recommend settling for a cheap thermal rifle scope with low resolution, because it makes identification very difficult. It may not seem like a big deal until you are in the field struggling to identify the fuzzy heat signature on your screen.

If you need a thermal scope around $1000, we recommend the little brothers of some of our top picks, like the AGM Rattler TS25-256.

As you research, you’ll find several thermal scopes below $2000. You may also try a clip-on thermal riflescope which are often less expensive because they are designed to work with a rifle scope you already own.

One-Shot Zero 

A thermal scope with the One-Shot Zero feature means you can take a shot, adjust your reticle, and your next shot should be zeroed in.

Power Consumption

The importance of battery life will vary depending on how you plan to you use your thermal scope. If you are going to be away from a power source and in the field for an extended period of time, you may not be happy having to change out batteries a few hours in.

Most scopes will either have a built-in battery that plusg in to a power source to charge or they will use rechargeable batteries. An external battery pack can generally be used with most models which can significantly extend battery life. The downside is that it also adds weight.

Some scopes have power-saving features like auto-shutoff timers or standby modes to help conserve power.

power consumption

Weight 

Thermal scopes are generally lightweight and compact, but added features increase the weight and footprint. Less expensive scopes may be heavier because they don’t make use of more expensive, lighter weight components.

Related Posts:

Durability 

While weight is an essential factor, so is durability. Options that are recoil resistant and shockproof are built to withstand normal jolts that are inherent in shooting. Another factor important in its durability is waterproof/ weatherproof ratings.

Ballistic Calculator 

It is also suggested that you buy a thermal scope that offers a ballistic calculator to help you find your targets easier. It will convert environmental data and target information into a trajectory correction to help you more accurately hit your target.

IR Technology

Thermal technology detects heat as electromagnetic radiation emitted by objects and beings within the infrared spectrum. Infrared thermal imagers detect that radiation ‘heat’ and convert it to an image that we can see with our eyes.

IR wireless uses wireless technology in devices or systems that convey data through infrared (IR) radiation. IR wireless is used for short- and medium-range communications and control. Some systems operate in line-of-sight mode; this means that there must be a visually unobstructed straight line through space between the transmitter (source) and receiver (destination). [1

When it comes to night vision vs thermal imaging, night vision requires at least a bit of ambient light to provide a picture while thermal imagers can be used regardless of lighting conditions, even in complete darkness.

ir technology

Reticles 

Another important factor that helps with accurate shot placement are your scope’s reticles. Having a variety of reticle options makes adjusting your shot to your conditions and preferences much easier. Most scopes offer at least two reticle options, but others offer as many ten with multiple colors to ensure reticle visibility even in different conditions. 

Magnification 

The right magnification for your thermal hunting scope is based on range. Lower magnification is used for short range and higher magnification makes it possible to detect and identify thermal markers at extremely long ranges. The higher the magnification, the lower your field of view.

High magnification power doesn’t equate to image clarity. Resolution is the best indicator for how clean the image is going to be.

Advantages of Owning Affordable Thermal Scopes

Thermal imaging scopes work to provide visibility in total darkness, allowing you to “see” through smoke, heavy cover, rain, or fog. Thermal scopes can also be used in daylight. Depending on your budget, you don’t have to sacrifice great features to own a scope that meets your needs. Many options with great features are available at lower costs.

And Our #1 Budget Thermal Rifle Scope is...

Our team unanimously chose the ATN ThOR 4 384 1.25-5x Thermal Smart HD Rifle Scope as the best budget thermal scope after this research-intensive review. It is packed full of features typically found on thermal scopes costing much more. This 384 resolution scope has the longest battery life of all of the options we tested. The ballistic calculator, rangefinder, and programmable reticle all work together to help you get the shot. Plus, this wi-fi enabled scope even simultaneously records video while you live stream.
