There are a lot of affordable optics out there, but it takes an investment for a good thermal monocular. With spectacular advances in thermal technology over the last few years, these remarkable devices have become indispensable tools in the outdoors. Along with the capabilities of a standard monocular, thermal monoculars have the ability to detect heat signatures and provide a clear real-time view of the world in complete darkness.

Whether you’re a wildlife enthusiast, a hunter tracking elusive game, or a first responder, a thermal monocular can be a game-changer in the field. Below, we researched and reviewed the top options available from optic brands like Pulsar and AGM to help you choose one of the best thermal monoculars to suit your specific needs and preferences.

How We Picked the Best Thermal Monoculars

When you’re investing in a thermal monocular, you need to know what you are getting. There are a wide range of capabilities and price points. Think about your intended use. Whether it’s for hunting, wildlife observation, security, or search and rescue, your requirements may vary, and different models are optimized for different applications. There are several key factors to consider, ensuring you make the right choice for your specific needs:

  • Resolution: Look for a monocular with a higher resolution, as it will provide crisper and more detailed images. A higher resolution is particularly crucial if you plan to identify smaller objects or targets at longer distances.
  • Detection Range: Different thermal monoculars have varying detection ranges. Consider the distance at which you need to detect and identify objects. A longer detection range is essential for hunting, security, or surveillance.
  • Price: Thermal monoculars can vary significantly in price. Set a budget and find a model that meets your needs within that range. Keep in mind that more expensive models often come with more advanced features and better performance.
  • Refresh Rate: The refresh rate, measured in hertz (Hz), determines how smoothly the image is displayed. A higher refresh rate, such as 50 Hz or 60 Hz, is crucial for fast-moving subjects or when panning quickly.

What to Consider When Choosing a Thermal Monocular


Thermal monoculars come in various resolutions, typically measured in pixels. Higher resolution provides sharper and more detailed images. Consider your intended use, as higher resolutions are also essential for long-range observation and precision applications.

Battery Life and Durability

Check the monocular’s battery life, especially if you plan to use it for extended periods. Some models offer interchangeable batteries for convenience. Additionally, assess the monocular’s build quality and durability. It should be able to withstand various weather conditions, including rain and extreme temperatures if you plan to use it in harsh environments.

Recording and Connectivity

If you want to record thermal footage or stream it to a display or mobile device, make sure the monocular offers these features. Some models even have built-in Wi-Fi or Bluetooth capabilities.


Q: What is a thermal monocular?

A thermal monocular is a handheld, portable device equipped with thermal imaging technology that allows you to detect and visualize heat or infrared radiation. Unlike traditional night vision devices that rely on ambient light or image intensification, thermal monoculars can create images in complete darkness or through obstacles such as smoke, fog, or foliage. These devices work by detecting variations in temperature and displaying them as high-contrast images, with warmer objects appearing brighter and cooler objects darker.

Q: Can you use a thermal monocular with a scope?

Yes, thermal monoculars can often be used in conjunction with rifle scopes for enhanced targeting and observation capabilities. This combination is commonly referred to as a “clip-on thermal scope” or “thermal clip-on.”

Q: Can a thermal monocular be used in daylight?

Yes, you can use a thermal monocular in daylight. Unlike night vision devices, which rely on ambient light, thermal monoculars create images based on heat signatures. They detect temperature differences, making them effective in a wide range of lighting conditions, including broad daylight.

Best Thermal Monoculars: Final Thoughts

When selecting the best thermal monocular for your specific requirements, it’s essential to consider factors such as resolution, detection range, magnification, battery life, durability, and user-friendliness. Brands like Pulsar, AGM, and Burris offer a range of models, each with unique strengths tailored to various applications. Remember to strike a balance between your budget and the features you need. With the right thermal monocular in hand, you’ll unlock a new dimension of vision and gain the upper hand in activities as you explore the world—and the wilderness—through the lens of thermal imaging.
