What Are Thermal Scopes?
Thermal scopes are sighting devices combining a compact thermographic camera and an aiming reticle. These devices use thermal imaging radiated from the target’s body heat. It does not use ambient light, so you can perfectly lock your targets even in complete darkness.
They can be mounted on various rifles, weapons, and guns. Often, these thermal weapon sights are used by hunters to aid in the detection of the game. These scopes are best for hunting feral hogs, coyotes, or rodents such as rats.
What Are The Benefits?
Many hunters and shooters opt to have a thermal scope because of their benefits.
1. It aids in detecting game
A thermal scope detects even the slightest heat radiated from a target, making every shot more precise. Animals generate heat. They are also warmer than their surroundings, so it is easier to detect them using thermal imaging.
2. It recognizes targets
A thermal scope recognizes live animals using their temperature displayed either as black hot and white-hot or even other colors depending on the thermal scope’s features. These colors represent their temperatures. Most of the time, these scopes can quickly identify targets. These sighting devices are only handicapped during extreme cold weather conditions.
3. It is durable
In today’s technology, a thermal scope had become as sturdy as night vision scopes. These devices can now withstand extreme weather conditions and years of abuse. They can even stand up to 30 caliber recoil. It also uses special lenses that are far more durable than ordinary lenses.
4. It has high-quality objective lens
A thermal scope uses high-quality germanium lenses, bringing the picture into better focus, captured by the microbolometer. It lets shooters see clear and crisp images, often partnered with a wide FOV.
5. It has dual purpose
A thermal scope lets shooters see even in total darkness because it doesn’t use ambient light to produce high-end images. Since it uses heat radiated from live targets, shooters can enjoy using this clip-on thermal scope during day and night hunting escapades.
Is It Better than Night Vision?
While both technologies are best in hunting games, we find the thermal scope better vs night vision scopes because it outranks the night vision scope for its dual-use. Thermal scopes can be used during day and night, while the night vision scope usually performs better during nighttime.
Another thing that we liked about thermal scopes is their ability to detect targets using body heat. We can use this sighting device in total darkness, unlike the night vision scope that still needs a light because it uses light to sight and lock targets. Although night vision scopes are more budget-friendly, we find these scopes as excellent investments worth every penny.
Either way, night vision and thermal scopes are both excellent partners in hunting games. It’s just a matter of preference.
How Does Thermal Imaging Work?
Thermal images work a little like the human eye. Instead of picking up on visible, reflected light, thermal imaging devices detect the heat released by an object. As you already know, objects, both hot and cold, emit heat. As that heat moves outward from the object, a thermal imaging device can see it. Like a camera, these devices have an optical lens, which focuses the energy onto an infrared detector. 
In other words, thermal imaging doesn’t rely on ambient light like night vision scopes. It picks up thermal patterns instead. This technology detects the subtle temperature differences and then creates a very detailed temperature pattern called a thermogram.
Factors to Consider
One of the factors that you need to consider is its battery life. Since thermal sights operate on battery power, you need to find a thermal scope with long battery life. Most scopes can last up to 8 hours on a single charge. Some thermal imaging scopes also provide an external battery that can extend its battery life.
Although a top-tier thermal optic has various pre-programmed reticles, we recommend that you choose a thermal optic that offers more reticle options. These options could be simple crosshairs, center dots, and the elaborate MIL-Dot configurations. Whether you intend to hunt or use these thermal sights in big games, you need to determine the reticles that your hunting expedition needs.
You also need to consider the durability of the thermal scope. Usually, an excellent thermal scope uses an aluminum body to make sure its long life span. Aluminum is more durable than just pure steel. When it comes to the lens’s durability, since thermal sights use germanium lenses, it is more sturdy than ordinary lenses.
Make sure to buy thermal optics that provide at least 10x up to 22x of magnification. The level of magnification must be aligned with your shooting pursuits. Also, the thermal scope’s magnification can either be optical or digital, so it would be up to you to decide which one to choose. Learn how to measure MOA here.
Thermal optics use digital technology to create a viewable image projected on a digital display, so it projects images with higher resolution.
Remember that screen resolution is the most critical factor in determining the clarity of the images your thermal optics will display. So, we suggest that you get a thermal scope with the highest resolution and thermal sensor you can afford.
If you want to own up your hunting game, you need to have a thermal scope with a detection finder and a thermal sensor that could give up an adequate range. Excellent thermal optics detect infrared heat signatures of objects and animals in the FOV at different ranges. Different sighting devices have different detection ranges, so find a thermal scope that can detect from mid-rang up to longer ranges, if possible.
Thermal scopes project different color options. As mentioned earlier, these colors determine the temperature of the living targets for identification. However, the most common colors used are black and white. These color options may display heat signatures as darker or lighter on the grayscale.
It’s not a secret that the best thermal scopes are expensive devices, so it’s best to get your money’s worth. It would be best if you found thermal optics that offer extra high-tech features.
Find scopes with digital compasses, laser rangefinders, GPS location, ballistic calculators, recoil activated video recording, fast refresh rate, and Wi-Fi streaming.
Thermal scopes can be mounted right in front of your daytime scopes using an extended standard Picatinny rail system. Therefore, we suggest that you look for thermal scopes that are compatible with most rifles and guns.
Weight & Size
Since thermal scopes carry more technology than traditional scopes, it’s not surprising that it weighs a ton more than traditional scopes, too. But having a heavy scope to add to your already heavy rifle could be challenging. Therefore, you need to find thermal scopes that are compact and lightweight.
Since thermal scopes use the advanced technology of thermal imaging and special lenses that protect them, they cost more.
However, even with the relatively high price of these devices, many hunters still choose to own them because they are the best partner in hunting and could also be considered an investment. However, before purchasing, you must still try to find a top-grade yet affordable thermal scope.
Based on our research, most customers find these thermal scopes efficient and money-worthy. They like how these products can detect targets even at long ranges. They also find the ballistic calculator useful and easy to use. The top-grade resolution of the images and fast refresh rate is also a huge plus for hunters. Overall, hunters who bought thermal scopes are happy with their purchases.
The top 10 thermal scopes mentioned above are excellent thermal scopes for hunting feral hogs, coyotes, or rodents such as rats. These scopes have special features that hunters find useful while hunting, such as a range finder, built-in rangefinder, ballistics calculator, and HD video recording and streaming.
