The Best Thermal Scope for Hog Hunting Reviews and Buying Guide

Hog hunting at daytime or nighttime could be a fun and rewarding activity and using a good Thermal scope for it can give you more from your experience. The best thermal scope for hog hunting can work regardless of the weather conditions and outdoor elements it could meet out there.

But if you’ve just started with your hog hunts and you’re searching for the night vision scopes or thermal scopes to meet your needs and demands, you’re probably having a tough time comparing your choices because there are so many of them on the market.

I’ve put up this guide to help you look for a good thermal night vision scope, each with their unique characteristics and features, including excellent detection of the target’s thermal signature to deliver a concise and clear sight picture. Also, I’ll be discussing the most sought-after features of what makes a good thermal imaging device. So, if you’re ready, let’s get started and later decide on the thermal scope for you.

What Makes a Great Scope for Hog Hunting?

Sitting in the darkness while waiting for the hogs to approach can fill you with excitement and anticipation, and when the hog is on sight, the action begins. For successful hog hunting, it all boils down to you, your rifle, and your scope. So before you set off in the wild, it is important to know the type of scope that you need in order to get your first kill.

Magnification Factor

A scope’s magnification pertains to the times that the target will be larger if you look at it through your scope.

The zoom extent of the scope depends on the number seen on its body, which means that a “3-9×32” magnification can zoom in on the target 3 to 9 times more.

Hunters can choose the type of magnification that they are comfortable with.

Fixed magnification allows you to zoom in on the target at a certain number only, and you can’t adjust it anymore.

For variable magnification, you have the option to adjust your view depending on the hunting conditions, your preferences, and the target’s visibility.

Note: Remember that the higher power you use, the less light will be able to travel through the scope. This dims your view and it negatively affects the clarity of what you see.

For example, the quality of the image may begin degrading, ruining the resolution and clarity in a digital thermal scope.

Thus, there should be a balance between effective detection range and magnification. This also has to do around the other factors, like display quality and sensor.

That is to say that it is not always a good idea to go with a higher power because it will affect the night vision performance of the scope.

Resolution quality

I suggest that you choose a thermal scope for hunting hogs that features a higher resolution. Always consider the highest resolution that you can buy with your budget.

Illuminated Reticle

The scope’s reticle is the crosshair seen when a hunter looks at the target. Reticles are important because it allows hunters to aim accurately and estimate their distance from the hogs.

In the past, there were different types of reticles that were used to markup the space seen through the scope, but since hunters do not stand in one place and have to be on the move constantly, the hunting optics industry created a reticle that is more versatile.

The illuminated reticle has the same crosshair as the other reticles but with luminous lines. This type of reticle is always visible, even if a hunter uses it at night or if their view is obstructed by the shadows of trees or rocks.

Illuminated reticle is powered by batteries and ambient light as they provide energy and capture light to accumulate it and make sure that you can see the hogs wherever they go.

Refresh Rate

I suggest getting the thermal scope for hog hunting that has the highest refresh rate. It refers to the frequency that an image will refresh per second. If you’re tracking a moving target, you should opt for a higher refresh rate thermal scope, like between 30hz and 60hz. The quicker the image will refresh with the higher the number.


Thermal sighting devices are not cheap, but they are more affordable now versus when they were introduced. You should expect to pay thousands of dollars for a high-end scope.

Ballistic Turret

When it comes to choosing a scope for hog hunting, the magnification and reticle are not the only ones that you need to consider to ensure a precise and accurate aim.

One important factor that you need to consider is the ballistic turret.

The turrets have sets of dials that allow you to adjust the elevation and the windage of the scope, so you can see the target better.

The ballistic turret lets you aim at the target even though you are far from it.

Objective Lens

Objective lenses are important for scope clarity. It is responsible for the scope’s brightness too. When a scope has a big objective lens, there is a higher chance that it will allow you to see your target even in dark areas.

The diameter of the objective lens on the scope depends on what you need to use the rifle for.

For hog hunting, it is better to get a scope with an objective lens diameter of 50mm and above because it uses higher magnification in low light, and it is suited for extreme long range targets.

Objective lens diameter of 30mm to 44mm are best suited for firearms with more recoil and for those who need a scope for low light hunting.

For objective lens diameter of 28mm and above, they are suited for firearms with litter recoil and for hunters who do close range hunting.

Lens Coatings

Lens coating is an invisible coat that enhances your sight. The coating increases the brightness and clarity and it increases light transmission. It also enhances your view to ensure that you hit the target wherever it is.

There are four different types of coatings that you can choose from.

The coated ones feature only one surface of the scope covered with a single layer.

The fully-coated ones mean that all the external glass is coated in a single layer, and it is the option that most hunters go for.

Multicoated lenses mean that one surface of the scope is covered in several layers, while the fully multicolored lenses mean that the scope’s external glass is coated in several layers.

For hog hunters, it is best to choose a fully-coated lens for clarity.

Field of View

The field of view pertains to how much of the surroundings you can see in the scope when your sight moves from left to right.

Field of view is important because it prevents tunneling, which is similar to going through a tunnel as you peak through the scope.

It often forms when you increase the magnification.

If there is a tunnel, it means that the scope has cut corners and has eliminated magnification.

With a wide field of view, you are assured that you can see everything, so you can still aim your target even if it runs away.

What is the best time to hog hunt?

You can hunt hogs anytime of the year, but many hog hunters claim that the best season for it is the deer season. Months from December to February are great because wild boars are searching farther and longer to look for food.

Do you need a thermal scope for hog hunting?

Yes, you need one for hunting hogs and other animals especially that you’re hunting in remote places, in the woods, open fields, and other places where there might be thick trees, grasses, and other factors that will negatively affect your vision like in night hunting.

What is the longest range thermal scope?

Aside from depth perception, index matched lens system, and weather resistance, you might want to know about the longest range thermal sighting device. On the market, you’ll find the highest quality scopes with a really broad detection range.

Those will help you identify the target positively at up to 4,000 yards far out. However, they can also come at a hefty price, which might not sound good for beginners who have a limited budget.

But worry not because there are also high quality thermals at affordable prices and can positively detect and identify a target at most 1,000 yards.

Is thermal or night vision better for hog hunting?

This is another common question for those torn between buying the best thermal scope or the best night scope. To help you decide, here is what to remember.

A thermal rifle scope will be able to detect moving objects or animals even from a long distance no matter the time of the day. It can have a better detection capability than night vision scopes alone. Thermals can help you see even in snowy or heavy rain.

A scope using thermal imaging technology also reads heat, particularly its processors, which can detect the differences in heat, and then make a digital picture of the animal or landscape in your scope.

Now for the best night vision scope– it works by collecting while simultaneously intensifying ambient light available. It can be moonlight or starlight, or any other sources of light at night, helping you see clearly even in dark conditions.

Most of these night vision scope and devices are built in with an infrared illuminator, which illuminates a target or the field even in total darkness. This IR light is invisible to your eyes, but combining it with a rifle scope for hog, it will appear like a spotlight.

An advantage that hog hunters can get from thermal imaging scopes over the best night vision scope is that they can see through smoke, grass, and fog because they don’t rely on light but read heat to detect and see an image. And at a much greater distance, thermals can easily detect warmer targets, too.

What brand thermal scope does the military use?

Aside from thinking about the best scope magnification, ruggedness, weather resistance, and other features of a thermal scope, you might also be curious about knowing what brand of thermals the military uses.

The most popular answer to this is the AN/PAS-13 Thermal Weapon Sight, which can provide the law enforcement and military with the ability of seeing deep into the battlefield day or night. This thermal scope is by Raytheon.


The best thermal for hog hunting offers unprecedented performance that you can rely on regardless of the outdoor conditions, weather, terrain, and environmental/shooting conditions.

It is equipped with smart features, like recoil activated video recording, laser rangefinder, built-in ballistic calculator, clear display, and Wi-Fi capabilities, depending on the selected model. In addition, it had the capability to provide you with a superb sight picture, field of view, and image quality even at a longer range.

We do hope that you’ll be able to compare these thermals along with their specific features so that you can find your best match for your preferences and needs. Good luck and happy hog hunting!
