A hunter is as good as his gear. Knowledge and technique can only take you so far especially if you are thinking about hunting at night than you require a unique sort of item. Something that can help you find and lock on to your target easily. Something like a thermal scope. So, if you are looking to buy a thermal scope for your rifle, then this article will be perfect for you. Here, I made a list of 5 best thermal scopes for hog hunting 2022. I will also provide all kinds of information about thermal scopes, including how they work, how to choose them and much more. 

So, let’s get started!

What Is A Thermal Scope?

A thermal scope is a thermographic weapon attachment that assists with vision and targeting in low light and other conditions where vision might be impaired (such as a snowstorm). 

These attachments can be mounted on all types of weapons (small and large) for helping with vision at night. They work by picking up the inferred light that emits particularly from warm objects. 

How Thermal Scopes Work?

As the name implies, thermal scopes work by picking up heat radiation. It has a camera that measures the amount of inferred light emitting from an object. Warm objects release more inferred light. So the camera shows warmer and brighter colors like white, yellow, red, etc.

Colder objects don’t release as much inferred light. In this case, the camera shows cool and dimmer colors like grey, black, violet and blue.

The camera has inferred sensors that pick up inferred light from different objects from your surroundings. Then the scope creates a thermogram and shows the inferred lights of different wavelengths in different colors. 

This separates warm live animals from the environment as they produce more inferred light than their surroundings thus appearing brighter. 

Types Of Thermal Imaging Systems

About all thermal imaging systems can separate live objects from their surroundings. But when it comes to image resolution and sensitivity, some methods are better than others. Of course, all thermal imaging systems come with their own set of advantages and disadvantages. 

There are two types of thermal imaging systems:

  1. Un-cooled
  2. Cooled

Un-Cooled Thermal Imaging System:

This is your standard thermal imaging system. They use inferred detectors that work under normal temperature. You’ll find them in any normal thermal rifle scope. 


  • Inexpensive 
  • They don’t have any moving parts
  • They are more durable
  • You can be used with batteries
  • They are quiet 
  • They activate instantly


  • Not as sensitive as cooled thermal imaging systems.
  • Detects changes in temperature of about 0.4 F which more than cooled systems.

Cooled Thermal Imaging System:

In this case, the imaging system has a cryogenic cooling unit. The unit cools the sensory system to a temperature below 32 F or 0℃. This makes them more sensitive to thermal changes. They are used in advanced thermal rifle scopes. 


  • More sensitive to heat radiation 
  • Can detect changes in temperature as low as 0.2 F
  • Can be used to separate armed individuals from non-armed individuals.


  • Very expensive 
  • They have moving parts 
  • They are not very durable
  • Activation takes time
  • They are relatively noisy
  • External power source required
  • They require repair or replacement within 13000 hours of use

Night Vision Vs. Thermal Vision

Both night vision and thermal vision are used for hunting game at low light conditions. Though their objectives are the same, they work very differently and have various ups and downs to them. If I had to tell you which one is better for hunting than I’m sorry to say I wouldn’t be able to. If you can afford both devices, then they both can help you in the detection and identification of your target.

Thermal vision uses inferred light emissions to detect minute differences in the temperature of different objects. This makes detecting live animals easier as they will always give off more inferred light than their environment making them stick out. This makes thermal scopes excellent for detecting live animals from great distances. 

The problem with the thermal scope is that the images produced might not always be recognizable. Even though thermal scopes are great at scoping out live objects from far away, it is tough to distinguish what you’re looking at. Sometimes the targets look like glowing blobs, and it becomes hard to tell if you’re looking at a deer or a human. 

Night vision

Night vision uses a different method for low light visibility. It pulls in the tiniest ambient light bouncing off objects and then amplifies it to allow vision. The sources of these lights include the moon, stars, etc. In the absence of natural light, IR illuminators can be used. They work like a flashlight for night vision scopes, but this light isn’t visible by the naked eye. Night vision devices produce structurally more accurate images making object recognition much more comfortable. 

The downside of night vision is its range. It can’t be used to pinpoint targets from a distance as well as thermal imaging devices. Also, obstructions such as foliage make identifying targets much harder as it captures light jumping off all objects.

When it comes to hunting the best tactic is to use them both. A useful technique would be to use a night vision scope along with a thermal monocular or binocular. The thermal device can be used to detect animals from afar and hidden in the foliage. Then using the night vision scope attached to your rifle, you can identify whether or not it is your preferred target and take the shot. 

But these are costly hardware. So I understand that everyone can’t afford both. If that’s the case for you, then my advice would be to go for a thermal scope. Yes, night vision scopes are better at identifying targets. But thermal scopes will be more useful in actually finding targets. And a lot of the times targets are recognizable enough for taking a confident shot. 

How To Choose The Best Thermal Scope For Hunting?

Thermal imaging rifle scopes are quite expensive. So you should know what you’re looking for before investing in one. I want to remind you that buying the best and most costly tech isn’t going to be worth it if you don’t need that extra juice. So it’s best first to understand what you need to buy a satisfying product. 

Things that you should consider before buying a thermal scope:

Your preferred game: Small game does not need scopes with high magnification. So if you are going to use the scope for hunting animals like rabbits, then buying a scope with more than 10X would be a waste of money. Smaller animals move faster. So keeping track of them with a magnification higher than 10x would be a nightmare due to decreased field of view. 

Weapon size: Magnification of the scope should be directly proportional to the size of the gun or its calibre. A smaller, less powerful gun should have smaller scopes. More massive long-ranged weapons should be paired with a larger scope with more magnification. 

Your distance from your target: A clear idea of how far your usual target would be. It will be hard to identify an animal any further than 300 yards with a thermal scope alone. So consider that before buying a thermal scope. 

Weight of the scope: You ever had to walk a mile to get to your hunting spot you’d know how hard it is to carry around heavy gear. A lighter scope will be more natural to carry around. On the other hand, a vast scope will probably have better build quality and more features.

Resolution and refresh rate: Scopes use a camera to show you thermographic images. The higher the resolution and refresh rate of the camera, the sharper and smoother your video output will be. Also, a higher resolution will result in a better digital zoom without blurring out images. A refresh rate of 30 Hz to 60 Hz is preferred.

Top 5 Best Thermal Scopes For Hunting

Choosing a scope for nighttime hunting can be a daunting task. The market is just full of choices. So it’s pretty understandable if you find yourself confused. Based on my years of experience, I’ve made a list of only five best thermal scopes for hunting, so you don’t have to waste time scouring the internet.

You can choose any one of them based on your budget and preference and be satisfied with your purchase.
