Are Thermal Scopes Worth It?

What Are Thermal Scopes?

Are thermal scopes worth it? But before we answer that we need to know what they are. Thermal scopes are optical devices that utilize thermal imaging technology to detect and visualize infrared radiation generated by objects and living beings.

These scopes, which operate in the infrared spectrum rather than visible light, produce images based on the heat signatures of their subjects.

These scopes transform thermal information into visible images on a display screen, with warmer items appearing brighter and cooler objects darker. So lets delve into, are thermal scopes worth it?

Are Thermal Scopes Worth It?

A thermal scope creates pictures or thermograms using infrared light (which is why it is also called an infrared scope or IR scope).

Thermal scopes detect radiation and produce images without the need of visible light. Thermal imaging scopes can be used at any time of day or night.

Thermal imaging can identify animals at large distances because they generate heat and are warmer than their surroundings. Many hunters use a thermal scope as a preferred tool.

Thermal scopes are beneficial for hunting in low-light situations and at night, even complete darkness, which a night vision scope cannot achieve.

Most thermal imaging scopes come with a reticle system, which not only helps you locate prey but also ensures that your shots hit their intended target.

Types of Thermal Scopes

Thermal scopes come in a variety of styles, each tailored to certain purposes and preferences. The following are some common types of thermal scopes:

Clip-on Thermal Scopes:

Clip-on Thermal Scopes


These devices are designed to attach to existing daytime scopes and convert them into thermal imaging scopes, offering thermal capabilities without the need to swap lenses.

Handheld thermal scopes:

FLIR Scout TK - Compact Thermal Imaging Monocular for Wildlife Viewing, Hunting & Outdoor


These scopes are portable and adaptable, designed to be carried in one’s hand for thermal monitoring on the go. They are frequently used for surveillance, search and rescue, and general thermal imaging applications.

Weapon-mounted thermal scopes:

EOTech ClipIR Thermal Imaging Monocular


These thermal scopes are designed to be mounted directly on rifles and used for shooting and hunting. They offer thermal imaging for target acquisition, targeting, and shooting in low-light circumstances.

Helmet-mounted thermal scopes:

MOD Armory FLIR Breach PTQ136 Thermal Monocular


In tactical settings, these scopes can be installed on helmets for hands-free operation, allowing users to maintain situational awareness while accessing thermal imaging.

When selecting a thermal scope, it is critical to evaluate its intended usage, whether it is for hunting, tactical applications, or general observation, as different varieties provide distinct features and benefits.

Thermal vs. Night Vision Scopes

If you plan on hunting at night, you’ll need a thermal or night vision scope to successfully acquire the target. However, while both of these devices will allow you to see at night, they are not identical.

For object detection, night vision optics utilize natural ambient light such as moonlight and starlight. They employ an IR illumination when there is no light.

Thermal scopes detect heat (infrared) energy in the surroundings and produce a thermal image.

Whether its day or night, thermal scopes can easily spot animals or moving things from a considerable distance. They have a greater detection rate than night vision scopes.

If you’re interested in predator hunting, a thermal scope is a must-have. Over the last decade, thermal scopes have revolutionized the game for nighttime hunting, making it easier than ever to go into the field.

Before you buy a thermal scope, here’s what you should look for.

Here’s some information on everything you need to know about purchasing a new thermal scope.

Image resolution

The resolution of an image seen through a thermal scope determines how clear it is. This makes it a critical factor to consider, since a low resolution will result in pixilated visuals, which will hinder your ability to hit the target. It is preferable to use a scope with a high resolution so that you do not lose out on vital details.

Refresh rate

The refresh rate is crucial in ensuring that the images supplied by the thermal scope are of high quality. The majority of thermal scopes on the market now are in the 30Hz to 60Hz frequency range.

The value represents the number of times the image is updated every second. The image will appear more lifelike as the number of refreshing increases. As a result, a thermal scope with a greater refresh rate is preferable for delivering high-quality images to you.


Optical and digital zooms are the two types of zooms available. You may magnify an image without sacrificing resolution thanks to the optical zoom. Digital zoom, on the other hand, enhances the image to allow it to be magnified. As a result, some resolutions may be lost, and image quality may suffer as a result.

A thermal scope with both optical and digital zooming capabilities is the best option. This enables you to zoom in and out while maintaining the optical zooming image quality.

Battery life

The thermal scope, like any other gadget, is powered by a battery. Some of them can run constantly for 5 hours, while others can run for longer. External disposable batteries are used by some, whereas rechargeable batteries are used by others.

Price range

The cost of a thermal imaging scope varies substantially based on a variety of criteria. They can start at roughly $1500 and go all the way up to $15,000 for the most expensive models.

Sensor resolution, fixed or interchangeable lenses, waterproof and non-waterproof bodies, and extras like Wi-Fi connectivity, on-board video recording, live streaming, and image capture are all factors that influence price.

As a result, they are pricey.

To buy a high-quality thermal scope, you’ll have to spend some money.

Are Thermal Scopes Accurate?

A thermal imager’s sensors can detect variations as small as 0.01 degrees, allowing it to determine whether a set of tracks is new. When tracking a recently shot deer, it can even detect the smallest blood drips.

Do Thermal Scopes Use Infrared?

A thermal scope generates pictures or thermograms by using infrared light (which is why it is also called an infrared scope or IR scope). Hot objects seem bright in a thermal image, while cold objects appear dark.


So the question remains: Are Thermal Scopes Worth It?

Having your own hunting equipment on hand is typically a smart idea. When you’re hunting, it’s all about what makes you feel comfortable and increases your chances of catching your prey. While you’re in the dark, you need to be comfortable. One of the most useful improvements you can make is a thermal scope.

If you’re interested in predator hunting, a thermal scope is a must-have. Over the last decade, thermal scopes have revolutionized the game for nighttime hunting, making it easier than ever to go into the field.

So, absolutely, thermal scopes are well worth the investment.
