Thermal Scopes for Hunting

A thermal scope is great for hunting, especially for night hunting of varmints such as coyotes, wild hogs, and the like.

How does a thermal scope work?

A thermal scope is excellent for detecting and for hunting nocturnal animals. When the thermal scope detects heat, it will light up the object, including inanimate objects if they are putting out a heat signature. They can detect the heat of the target and can operate in temperatures ranging from -13degF to 122degF.


The temperature range of a thermal scope is measured in hertz (Hz) and will vary from device to device. The thermal imaging system of a thermal scope takes the form of a camera that can detect heat signatures. These heat signatures of the animal are shown to the hunter using the thermal scope in hot white or black. The thermal scopes on the market today are not just one color palette, as they used to be. Thermal scopes now come with many different color options to choose from. The following are some of my favorite modern colors: -Black and white (all time standard) -Vibrant hues like pink or orange. This is what makes thermal scopes so wonderful for night hunting. By the thermal scope showing you your prey animal lit up; right out of the dark of the night these hunting scopes enable you to hunt even when there’s complete darkness, which means you’ll never have any trouble finding what you’re hunting for at night!


A thermal scope is very effective for detecting game animals in such environmental conditions as dense fog, dust, and complete darkness. Hunters can use a thermal scope to uncover game animals that may otherwise stay hidden from view due to their location within thick foliage, wooded areas, or because the game animals are more active only under the cover of darkness.


Know the Differences: Thermal Scope or Night Vision Scope

Night vision scopes use electronics to amplify the amount of light in dark circumstances and use this light to enable you to see in the dark. Night vision does not generate an image if there is no light. Which makes a huge difference between the two hunting scopes.

Thermal scopes pick up the heat (IR radiation) being given off by an object, such as an animal, which is the reason why a thermal scope can be used in complete darkness.

Key Characteristics of a Quality Thermal Scope

You’ll want to take some time to get to know some of the most important features of thermal scopes before you make the investment into buying one for hunting.


Thermal Scope Magnification

The magnification feature is a crucial feature for thermal scopes. It allows you to zoom in on a target in real-time. The higher the magnification, the more detailed the image. Some thermal scopes can have up to 16 times magnification, while others offer fixed magnification. You can choose between optical and digital magnification. Digital magnification uses software to magnify images, while optical magnification uses lens adjustments. Optical magnification provides better clarity at maximum enlargement. The refresh rate of any thermal scope you choose to buy is important because it keeps the image crisp and clear.


Thermal Scope Resolution and Sensor

The resolution of the thermal scope is not the only thing you need to know about. You’ll also want to pay close attention to your thermal scopes sensor resolution, too.
Some thermal scopes will have an 800×600 display but the thermal sensor is only 320×240. The thermal images from your scope will never be as clear and detailed because it doesn’t have the same resolution – compared to a similar scope with the specs of a 640×480 thermal sensor.


Thermal Scope Reticle Pattern

Some thermal scopes come with a four-line standard reticle while others have a single-dot one. Night hunters generally opt to use a crosshair 4-line reticle when using a thermal scope. They find that this type of thermal scope reticle helps improve their shooting accuracy and greatly improves their hunting success at night.


Thermal Scope Refresh Rate

As a rule of thumb, the more frequently a thermal scope is refreshed or thermal scopes with a higher refresh rate will provide a much clearer image of the hunting scene.


Thermal Scope Zoom Type

Digital zoom is more affordable and magnifies by using software. An optical zoom makes use of a lens to deliver a sharper image – but is more often more expensive than digital zoom.

Thermal Scope Lens Diameter

The larger the diameter of the lens on a thermal scope, the greater the field of view. Also, the more expensive and heavier the thermal scope will be.

Thermal Scope Battery Life

A good quality thermal scope can offer power for up to 8 hours – After a single charge.


Thermal Scope Warranty

Buying a thermal scope can be a big investment for most hunters. So, any hunter thinking of adding a thermal scope to their hunting gear should pay attention to the warranty length offered by the thermal scope manufacturer. Most, if not all of the thermal scopes on the market come with some sort of limited warranty, these warranties vary from company to company. We always suggest that hunters ask the manufacturer for the “full” warranty information of the hunting scope when they’re still in the decision-making process. The full warranty information will contain an item-by-item breakdown of the warranty coverage you can expect.


Other Useful Details About Thermal Scopes

We’ve touched on this feature already. But we’ll explain it more here. One of the most important features of a thermal scope is its magnification. Magnification defines how far the thermal scope can zoom in. The higher the magnification, the clearer the image will be. If you are looking to shoot at long distances, a higher magnification is a must when hunting.


The best thermal scopes can positively identify heat signatures of targets at 4,000 yards. An entry-level thermal scope generally performs well at a distance of 1,000 yards or less. So, if you’ll be shooting further, it would be best to look at hunting scopes with a higher magnification level.


A thermal rifle scope should be able to detect and find targets in the distance. You can use a thermal scope to see game animals through dense foliage, which can be hard to see with other types of scopes. When hunting, it’s important to know local laws before hunting with a thermal rifle scope. In addition, it’s important to consider the field of view of the thermal scope.


Many thermal scopes nowadays are often paired with a camera or have a built-in system for recording and even uploading the video, as it is seen through the thermal scope during its use. These thermal scopes or thermal scope accessories can be used to take pictures and videos of your targets for later observation and review.



It can be difficult for hunters to choose which thermal scope is best to buy. There is a lot of information on the internet. A quality thermal scope will work great from the time you buy it, and will continue to perform well for a long time to come. So, taking the time to research prior to making an investment in a thermal scope is always the best thing to do.
