Even though this is an advanced scope, the user interface remains simple. The intuitive menu system and the ergonomic button layout add to the overall ease of use.

The ATN Thor 4 640 also has a built-in smart rangefinder for distance calculations. It helps to center the reticle and improve your accuracy levels.

Lastly, this isn’t a cheap device. With all the advanced features, it’s not the right pick for newbie hunters.

But if you want to drop hogs or coyotes at night, this is definitely a great companion.

Now, the Thor 4 640 thermal scope is available in four different magnification ranges. The 1-10x version that we reviewed is the cheapest option with a human detection range of  830 meters.

The other options come in 1.5-15x, 2.5-25x, and 4-40x magnification ranges. The detection range and the field of view will change accordingly.

The 320×240 and 12 μm ATN Obsidian sensor offers a better detection range and image quality.

In fact, the overall display quality is good enough to compete with thermal scopes of a higher price range.

In terms of other features, the scopes are almost the same.

You get the same lightweight design that is crafted from hardened aluminum alloy. The recoil resistance is sufficient for using the unit of high caliber weapons.

ATN also marks it as weather resistant.

Being easy to mount, the Thor LT 320 is a good choice for any weight-sensitive base.

A refresh rate of 60 Hz in an entry-level scope is a great addition. That makes the HD display more fluid and responsive.

ATN offers dual color modes here – black hot and white-hot color. Picking between them is a matter of personal preference.

There’s nothing fancy in terms of the accessories attached. You get an eyecup, scope cover, USB C cable, and lens tissue.

The Li-Ion battery offers 10 hours of running time. That’s good enough for a whole night of the shooting.

And the best thing about the ATN Thor LT series is…

These scopes are straightforward to use. Without fancy features like ballistic calculators and range finders, they are a great choice for newbie shooters.

The scope also comes in 3-6x and 5-10x magnification options. You will get a human detection range of 910 and 1620 meters, respectively, with these models.

Buying Guide for Night Vision Scopes

Like everything else, there are a few things that you need to keep in mind before picking a night vision scope. Here’s a quick look at a few of them.

The Field of View and Magnification

The field of view is the width of the area within your vision at a certain distance while using a scope. For example, it can be marked as 22 feet at 100 yards. A wider field of view makes it easy for a hunter to observe the prey more easily. It also makes the tracking of movement easy.

Magnification is about enlarging any object at a distance. It can be both digital and optical. Optical magnification offers better clarity than digital magnification. While higher magnification is useful for long-distance shooting accuracy, it can also affect image clarity. Basically, the amount of magnification you need will be as per your shooting needs.

The thing is, the field of view is related to magnification. When the field of view is increased, magnification will come down and vice versa. It’s best to scan an area for detecting the prey with a wide field of view. Then you can magnify the image for better clarity.


The fact is, night vision technology doesn’t provide an extensive range like a high-quality rifle scope. So, while picking an ATN scope with night vision, knowing the recognition range is important.  For any night vision scope, the recognition range will vary depending on the ambient light available. That means you’ll get better performance on a full moon night than an overcast one. 

This is where a scope with an Infrared Illuminator (IR) can enhance the overall visual range. It   

emits infrared light, which is reflected back to the scope. This allows it to generate better images in total darkness. However, these have a limited range and will increase the overall weight of the scope.


The power source of any scope is a vital aspect that can’t be neglected. And you know what’s worse? Finding out that the batteries in your expensive night vision scope last for just 3 hours.  So make sure that the device comes with batteries that last long. Remember, the weight of the battery pack will determine the overall weight of the scope.

Weight and Size

The weight of a night vision scope increases as the magnification levels go up. Knowing the weight along with that of the battery pack is essential. A heavy scope will add to the overall weight you need to carry. This can result in fatigue and affect the accuracy of the shooter. Also, observing for long periods or making standing shots are trickier with a heavier scope. So make sure you pick the right weight depending on your hunting style.

Image Clarity

Lines Per Millimeter or LP/mm is another important factor affecting the overall clarity of a night vision scope. This measures the resolution of the image intensifier tube in the scope. In general, the higher the value, the better is the clarity of the optics. Generally, a resolution of 60 to 70 LP/mm is considered suitable for a scope.

But that’s not all. The quality of the lens determines the amount of distortion that is created. Distortion becomes even more pronounced at longer ranges. With higher levels of distortion, clarity is adversely affected. But high-end glass lenses can reduce distortion by a lot.

So LP/mm isn’t the final call on clarity. A buyer should factor in any potential levels of distortion. Distortion is caused by the materials used to create the lens you are looking through. Note that distortion will affect clarity and cause issues with making out specific features of a target.

Night Vision Technology Generations

If you don’t know this already, night vision technology advances by generations. So picking a device from the older generation may not meet your exact requirements. While generation 1 devices are cheaper, they were developed in the 1960s. So they don’t offer the best range or resolution. But if you’re looking for something affordable within a small range, they can be very effective.

Generation 2 night vision scopes are more advanced with a better range. They also have better battery life and are more durable. But in case you are looking for the latest features, you can stretch your budget all the way to pick a generation 3 scope. These are military-grade products with the latest technology. They offer the best image clarity in darkness and the most extended ranges.

The thing is, some night vision scopes are marketed as generation 4 devices, even though there isn’t such a strict classification. This category was introduced in the US army but failed to meet their exact requirements. So the terminology was withdrawn.

Pros and Cons of Night Vision Scopes

All night vision scopes are electro-optical devices that amplify the ambient light. The amplification is done through photomultiplier tubes and a screen coated with a special phosphor compound. However, some of the latest night vision devices also use digital technology.

Here are some of the pros and cons of night vision devices.


  • Night vision devices produce a more natural image
  • The devices are tougher and can withstand rough handling
  • They come with a more affordable price tag
  • Night vision scopes allow you to see through a glass surface, unlike thermal imaging devices
  • They provide excellent battery life


  • The traditional technology doesn’t work in very bright light or in complete darkness
  • They can’t operate through dust, fog or smoke
  • Night vision can’t recognize camouflaged objects
  • Night vision affects the depth perception while viewing.

Buying Guide for Thermal Scopes

Choosing thermal scopes from the wide range of options isn’t an easy task. However, there are quite a few factors that are the same as the night vision scopes. Take a look at this detailed discussion about the various aspects of picking the right thermal scope.

Pros and Cons of Thermal Scopes

The technology used for thermal imaging makes these scopes a more versatile choice. Still, there are some disadvantages associated with them.


  • These scopes can be used in all kinds of lighting conditions and even in complete darkness.
  • They are useful for tracking through the detection of residual heat from footprints and handprints.
  • They can see through smoke and dust.
  • They can identify camouflage.
  • Can be used for long-range target identification.


  • The identity of the target can’t be confirmed through thermal vision.
  • The technology is more expensive.
  • They can’t operate through glass.
  • Not the best performance in rain or fog
  • High-temperature objects in the surroundings can mask the original target.

Do I need to take any precautions while using night vision?

It’s best to take the following precautions while using any ATN night vision device.
-The device shouldn’t be aimed at a bright light source. 
-Don’t attempt to disassemble the device without professional assistance. 
-It’s best to avoid dropping or shaking the device.
-Don’t touch the objective lens of the NVD with bare hands. It’s best to touch it with a soft and non-abrasive piece of cloth.
-It’s best to keep the device stored in a case to prevent any damage.

What is digital night vision?

Unlike standard night vision devices, digital devices use a CCD (charge coupled device) image sensor The pixels in the sensor generates the digital image on the screen. The advantage is, they don’t need to be kept away from bright daylight like traditional night vision devices. This is possible as they don’t have light intensifier tubes, which get damaged by bright light.

How far can you see with a night vision device?

The detection range of a night vision device depends on many factors. When you’re trying to identify the details in an object, this is called the recognition range. In some cases, you will be able to detect movement but won’t be able to identify the object clearly. This is called the detection range of the device. Each device comes with a specific range depending on the sensor and optics capabilities.

Also, the amount of ambient light affects the overall detection range. For example, you will see better on a moonlight night than on an overcast night. In general, the recognition range can be between 75 to 100 yards. The overall detection range for devices can be 500 yards or more.

Do I need an Infrared Illuminator?

As we have already mentioned, the IR illuminator projects out a beam of infrared light that’s invisible to the naked eye. Basically, you can think of it as a flashlight that emits infrared light. But this light can be captured by the night vision equipment for generating better images. In very dark conditions, an illuminator can be helpful.

The range of illuminators vary. Short-range illuminators can work up to 30 yards. Whereas long-range IR illuminators can through a beam of light as far as 500 yards.

On the whole, it’s a great accessory to enhance your vision range in areas of extreme darkness. However, you can’t operate covertly while using an illuminator. Anyone with even a Generation 1 night vision scope will be able to spot you easily.

How long will a night vision device last?

Actually, these devices can last for a lifetime when handled and maintained in the right manner. A generation 2 device can last for 5000 hours. In comparison, a generation 3 device will last as long as 15000 hours. But in real-life use, you can expect a life of around 12000 hours. Make sure that you follow the owner’s manual for taking care of the scope.

Do I choose a thermal or a night vision scope?

We have already discussed the pros and cons of each type. The latest night vision scopes deliver excellent image quality in almost all conditions. It’s difficult for a prey to hide when you’re using such a device. Even then, the generation 3 night vision devices are a good choice for  hunting at night. Moreover, they are more affordable. So when you’re on a budget, it’s best to pick a high-end night vision scope than a low-end thermal scope.

How to update the firmware on ATN rifle scopes?

Updating the firmware is pretty simple. Firstly you can download it from This can be copied in the microSD card of the device and inserted in the scope. Once the scope is turned on, it’ll prompt for updating the firmware. Once you select the right option, the device will update itself.


So here it is.
