Features to look for in a great hunting thermal imaging monocular
Before any of your hunting thermal vision monocular purchases, there is a need to know several features that will determine whether it is worth the buy or not. This is necessary especially for hunters who do not want to engage in multiple purchases during their hobby.
Also, it ensures that your thermal imaging monocular will be flexible and long-lasting, even to future holders.
What is meant by a working condition? The answer is simple. These are the optimal scenarios in which a thermal imaging monocular works, meaning that no interference will happen.
This is important to know so that users will not be shocked at why their monocular is not functioning properly.
Some good working conditions for a handheld thermal monocular are nighttime as well as places where there is a clear difference in temperatures. For example, using a thermal imager at night will be beneficial since the contrast of the subject against the environment is vivid.
A clear example of this is spotting a deer in the forest. Since the forest is cold and a deer is warm-blooded, a hunter will distinguish it easily.
Clarity and Thermal Sensor Resolution
Clarity and resolution are crucial features when choosing a hunting device. As for why I have a great explanation. But before that, we should learn the meaning behind the words in terms of monoculars.
Clarity refers to how vivid an image produced by the whole system is, despite the elements present in front of it. It also matters greatly when viewing objects at great distances. Some monoculars that have a low quality will behave with lower clarity, meaning that what is in the real world won’t be reflected by the system.
On the other hand, the resolution is defined by how many pixels will be produced by the thermal monocular. Similar to a handheld camera, the higher the resolution, the better the result will be. It is safe to think that monoculars that have a higher resolution need to have high-end lenses and better processing power.
Not only that, but they must also have exceptional raw materials as well as builds so that the system can compensate for the quality. In this field, it is needed to have high-quality binoculars. Thus, it is always recommended to invest rather than be stingy since it will benefit you in the long run.
A thermal imaging monocular requires some processing power since it has to convert thermal data into light or visible data.
This is done by sensing infrared radiation in an object and relating it to the radiation of the surroundings. With the resulting heat map, the temperature differences are laid out, and a user can easily see everything even without the presence of light.
For this reason, a good monocular needs sufficient thermal technology computing power to function properly. If this is not satisfied, then the result would be a system that will not have enough juice to unveil the environment.
Not only that but special devices and sensors are necessary such as cryogenic coolers and radiation identifiers.
What good is a thermal monocular if you cant apply it to your hunting activities? A buyer should always be wary of the limitations of the product so that it will be properly used in the field.
For example, one must guarantee that the monocular is not too bulky or even heavy to use as it removes the portability of the device. Furthermore, it should also be durable and able to withstand accidents so that it will last for a long time.
This is the part where price plays a fairly huge price. After all, a cheap monocular will never have the same capabilities and usability compared to an expensive one. As a seasoned hunter and gear enthusiast, I will always say that it is better to invest in costly gear rather than to spend money on a cheap one.

Buyer Guide & FAQs
What to look for in thermal imaging monoculars
Good Clarity. This refers to the final output of the thermal imager to the display. As much as possible, get a monocular that is known for having sharp images as well as good contrast. This will help determine the target apart from the surroundings better.
Great Magnification. Never neglect one of the main purposes on why you are buying a monocular. Be wary of products that display that they have large zoom values but the result is still blurry and pixelated.
User Interface. What does a user interface refer to? Well, it is the design of the navigable software. This part of the device will always make or break the overall feel. This is because a monocular with tons of good features will be useless if the user interface will not be easy to understand. The same is true the other way around.
Egonomics. Ergonomics refers to the human comfort aspect of the device. This includes things such as the grip, strain, as well as muscle pain that it brings especially in long usage durations. A good monocular must take these into account and have a build that is easy to grasp and carry around. Not only that, but the buttons on top of the camera must be reachable by the fingers that are free during the portability tests. If such conditions are satisfied, then it is deemed to be an ergonomic monocular.
Different types of thermal imaging
Scopes. These are add-ons to your guns or rifles that are helpful when doing night hunting. Thermal imager scopes are a bit smaller than your regular monoculars, but they still offer the same base functionality. However, due to their size, some features might be different or toned down. Despite this limitation, the scope thermal imager is still a favorite amongst hunting enthusiasts due to its versatility.
Binoculars. A binocular can be seen as two monoculars paired up with each other. This means that you will be able to view both from the left and right eye. Binoculars are great in terms of comfort as they reduce eyestrain which comes from unequal magnification viewing. Furthermore, they are better suited for long hunts.
Key points for consideration before buying?
Before buying thermal imaging monoculars for hunting, you must first decide if you want an entry-level, mid-range, or high-end device. With this category as your guide, you will know if the value of your purchase is equal to the efficiency.
For starters or beginners, it is usually recommended to purchase an entry-level monocular just so they can get a hang of how things work. As time passes by, they can then switch to a more expensive model with more features compared to the basic ones.
Another key consideration to think of is the preferred time of the hunt. Thermal imagers work well during night and day, but daytime operations might have a stark difference, this is due to the increased environmental temperature that can mess up the readings as well as the resulting heat map.
Lastly, there is a need to do a background check of the company that you will be purchasing from. You do not want to end up getting scammed for your money just because you were not careful. Some known manufacturers in the field include LEICA and FLIR. By following this guide, you will never go wrong with your purchase.
Is thermal or night vision better for coyote hunting?
Both products have their strengths and weaknesses. However, thermal imagers are passive and do not rely on a light source and this makes them better at night. On the other hand, night vision relies on the ambient light source to function. If none is present in the surroundings, then an infrared light emitter will be utilized.
Can you use thermal imaging for hunting?
Absolutely! One of the main purposes of having a thermal imager monocular is hunting. These devices are especially helpful during the night due to their capabilities in viewing areas without the need for any illumination.
Are thermal optics illegal?
Yes, thermal optics are very legal. They are even used in law enforcement and security.
Can thermal see-through bush?
A thermal imager can see through the bush provided that there is a subject with a higher temperature behind the bush. The imager will display the heat map of the creature and you will have full vision.
What is the life expectancy of a thermal scope?
Thermal scopes, with proper care, should last for 5 years or more. These include proper maintenance, cleaning, and even check-ups.
Now that you know about my top picks, it is time for you to choose yours as well. Personally, my best choice is the FLIR Scout since it fits me perfectly as someone who wants fast skirmishes and comfy carries.
No matter what you choose, you should always have the advantage in night hunting when using a thermal monocular. Take care of your device through proper maintenance and preventive measures to avoid component deterioration.
Remember to enjoy your new gear and be safe during your activity!
