Best Thermal Monocular Review and Buying Guide

Thermal monoculars are a great tool for hunters, hikers, and law enforcement personnel alike. They are designed to detect infrared radiation and are capable of scanning for animal activity and other heat sources in the dark. With the wide range of models and brands available, it can be hard to choose which one is the best for your needs. To help you out, we have compiled this guide letting you know what to look for when selecting the perfect thermal monocular for your application.

What Is a Thermal Monocular?

A thermal monocular detects infrared radiation and converts it to an image. This can be used to see through the dark by detecting the heat produced by animals, human activity, and other sources. Thermal monoculars provide users with a better view of their surroundings than night vision goggles. This makes it a great tool for hunters, military personnel, law enforcement, and hikers.

Types of Thermal Monoculars

When it comes to thermal monoculars, there are two main types: uncooled and cooled. An uncooled thermal monocular is powered by two AA batteries which provide up to 4 hours of battery life and is the more affordable option of the two. They require no power source other than the batteries and provide a clear image in low levels of light. A cooled thermal monocular, however, is more expensive and is powered by a larger battery pack. This type of thermal monocular provides a clearer image, even in complete darkness, due to the cooling of the image sensor.

Important Features to Consider

When selecting the right thermal monocular for your needs, there are a few key features to consider:

  • Size: Thermal monoculars come in a variety of sizes and weight, so it is important to choose one that is lightweight and comfortable to carry.
  • Optical Magnification: This is an important factor as it determines the detail of the image you will be able to see. The greater the optical magnification, the better the image.
  • Field of View: Each thermal monocular will offer a different field of view. This is the area that you can observe at any one time. A wider field of view will allow you to scan a larger area at once, while a narrower field of view offers more detailed information.
  • Detection Range: Depending on the model, a thermal monocular has the ability to detect targets up to a certain distance. This is specified by the manufacturer so make sure to check to see what range your model has.
  • Image Quality: You want to make sure the image quality is up to standard, as this will determine the level of detail and clarity you have when viewing objects at night.


Thermal monoculars provide a great way to see in the dark and detect objects even when light levels are extremely low. It can be hard to choose the right one for you, but with this guide, you should now have a better understanding of what to look for when selecting the perfect thermal monocular for your needs.
