A Comprehensive Guide To Finding The Best Thermal Scope Around

A Comprehensive Guide To Finding The Best Thermal Scope Around

Hunting is a discipline that requires quite a bit from the people who practice it. As a hunter, you need to have a keen sense of stealth, the necessary physical dexterity and endurance to stalk prey for prolonged periods, and quite a bit more. First and foremost in a hunter's skill set, however, is to possess eyesight comparable to a hawk's.

Just like the eagle-eyed bird of prey is the supreme hunter of the skies, you can be the best one on earth when you can see your target from far away. Unfortunately, hunting requires more than just the ability to see far; in that case, any old 20X scope would be able to get the job done. The best thermal scope can change that.

Different Thermal Scopes

A thermal scope is a scope that can be used to track the heat that is being emitted by an object or a living being. Since the vast majority of creatures that we hunt will be warm-blooded, they will stand out against the background, as our surroundings are nearly always cooler than our blood.

Over the course of this article, we’re going to be presenting our thermal imaging scope reviews since it can often be a challenge to determine which model will work best for you. In our thermal scope reviews, we’ll be looking at the sets of features that make these scopes some of the best models on the market.

Beyond our reviews searching for the best thermal scope for hunting, we’ll also take a look at some of the features that you should search for in the ideal model. If you’re new to buying these scopes, you’ll find our buying advice invaluable, as you’ll be able to determine for yourself whether or not a product is best for you.

Thermal Scope Vs. Night Vision

Many people are confused by the difference between night vision and thermal imaging, and it makes sense since they operate using similar methods. Both of these kinds of scopes or visual devices use the infrared spectrum to improve your visibility, but they differ in what they display.

While a thermal scope shows you heat waves as lighter areas, a night vision scope will use infrared light to improve what you can see in the dark. A thermal scope will not necessarily allow you to see in the dark, so there are also infrared thermal night vision scopes which combine both of these functions.

Benefits Of A Thermal Scope

So how does a thermal scope benefit you? The main advantage to using one of these scopes is that you’ll be able to spot targets that would otherwise be hidden by foliage or other obstacles. Since any body heat that is emitted by your target will be displayed as a brighter area, you’ll be able to spot any prey with ease.

On What To Pay Attention When Choosing Your Thermal Scope

Before you buy yourself a brand new thermal scope here are few things you should pay attention on:


When it comes to choosing the best thermal scope for the money, you'll have to consider the size of it, even though that may not seem like such a critical characteristic. Most of the time, a larger thermal scope will either be more powerful, or it will feature higher definition, but there are also downsides.

Thermal Scope

Most thermal scopes are already relatively bulky, but as you reach the larger models, they start to inconvenience you. Most hunters don’t want to have to deal with a firearm that is larger than it has to be, as it makes it harder to remain stealthy and it also makes it harder to handle your hunting rifle.


You’ll also want to consider the purpose of your thermal scope, as you can use them for a variety of different applications. First off, you can use one of these as a rifle scope, and that tends to be a common use, though others prefer to use these as a secondary (spotting) scope, as they are less versatile than standard models.

A thermal scope may cause some issues due to a smaller field of view when compared to regular ones. If you want to be able to see a larger area through your scope, then you’ll likely want to leave a standard model mounted to your gun while using a thermal scope for target acquisition.


When it comes to digital thermal scopes, you’ll have to consider the image resolution when making your choice, as a hi-res scope will make it much easier to see your target. Of course, you’ll also have to consider your budget, as high-resolution thermal scopes tend to be quite pricey when compared to other models.

The resolution of your digital thermal scope will determine the number of pixels that it can display, so it will typically need to feature more powerful components. As we already mentioned, thermal scopes that are capable of more detail will usually be larger so that they can contain all of the needed parts.

Extra Features

When choosing the right thermal scope, you'll also want to take a look at the additional features that come included with it. Some models will come with extras that make it easier to aim or shoot while some will include additions that improve their ease of use or even their durability.

Ballistic Calculator

This is one of the most advanced features that you can find on a thermal scope, provided that it is in computerized form. There are more basic forms of ballistic calculators which are known as bullet drop compensators (BDC marks), which use the average height of a target to determine a ballistic trajectory.

Adjusting Thermal Scope

More advanced thermal scopes will come equipped with a ballistic computer that will determine where you should aim based on your rifle's caliber and your distance to the target. There are many ways to determine how far away you are from your quarry, which leads us to the next extra.


When determining your bullet’s trajectory or where you need to aim, one of the most important things that you can know is how far away you are from your intended target. Many scopes feature markings which will allow you to estimate your range to the target, though these aren’t precise.

A rangefinder will make it much easier for you to find out how far you are from the target that you're hunting. Most modern rangefinders work using lasers. A laser is shot at the target, and the rangefinder calculates how long it takes for the laser to reach it, giving you your distance.
