Those who love supporting domestic production should seriously consider buying this thermal monocular if you are looking for one. This thermal imaging device is produced in the United States, which is one of the many guarantees of its quality.

Although there are no significant drawbacks, some customers note that it would be convenient to include a lens cap in the package. Despite the glass being durable enough, you never know what might happen to such a fragile detail of the device. You would not want to spend all that money on a thermal monocular just to get the main part damaged quickly.

Thermal Monoculars and Night Vision

A lot of people have a similar association for both a thermal monocular and a night vision device. It is quite obvious that the two mechanisms help people to see the target in difficult conditions better. Night vision monocular, as well as thermal monocular, is widely used by hunters to look for prey at night. However, the latter can also be used during the day, if there are some obstacles like heavy rain, dense fog, or even smog.

Using a thermal monocular during the day can be very beneficial even if it is clear outside. The animals will not stand still and wait for you to catch them. If you happen to lose the track of your target, handheld thermal monoculars can come in handy. They allow you to see the animal even if it has escaped from your line of sight. You will not be able to do such a trick with a night vision monocular.

Thermal Monocular Usage Areas

Although we have discussed thermal monoculars only in terms of their hunting device function, there are plenty of other ways that one can implement a thermal imaging device in their life. While not all of them might be applicable to an ordinary person, it might be interesting for you to know what spheres of life frequently use thermal monoculars.

Any thermal monocular has plenty of functions. Here are some of them:

  • Providing security. If you feel like security cameras are not enough, you can always install thermal devices around your property. They are sensitive to any signs of intrusion, and even if the cameras will not see a person in the dark, the thermal sensor will.
  • House inspection. If you are building or renovating a house, thermal sensor checking can save you a lot of money in the future. The device can indicate any gas leaks, bad insulation, or water leaks that might not be visible to a naked eye.
  • Medical observations. Hospitals sometimes use thermal sensors to find problematic spots on your body. If there are damaged tissues, inflammation, or fever symptoms, the scanner can indicate where exactly the problem is. This allows doctors to treat any health troubles quickly.
  • Marine military. It is no secret that the military uses thermal scopes and sensors on their ships. They do not only help to identify enemies quickly but also detect any potentially dangerous icebergs or people in the water who might need help.
  • Production engineering. To make sure each step of a production line works properly, engineers use thermal imaging devices to indicate any overheating. If there is some part of the mechanism that has a higher temperature than usual, the problem is urgently fixed, so that the production would not have to stop.
  • Electricity inspection. Similar to the production engineers, electricians often use a thermal sensor to detect any signs of overheating in the electrical systems. This helps to prevent many serious problems caused by malfunctions of electrical devices.
  • Law operations. Many of us have seen how police or the FBI tracks hidden criminals by using a thermal sensor. It is widely applicable in real life as well, and it allows you to catch any lawbreaker even without seeing them.

As you can see, there are a lot of ways by which a thermal device can be used. Although not all of us look for icebergs or catch offenders daily, it is still important to know how you can implement even a small handheld thermal monocular in case of an emergency.

Good Thermal Monocular Buyer’s Guide

Analyzing all the products on the market might be a complicated and overwhelming task, especially if you have never owned a thermal monocular before. Those who are looking for their first thermal imaging tool might not be sure what to pay attention to. There are many products that claim to be the best ones, but in fact, only a few of them deserve to be called this way.

So, how to find the best thermal monocular if you do not know what you are looking for? First of all, you need to decide for what purposes you need the thermal device. Whether it is long-range or short-range shooting, video recording, orientation in the area, or any other reason, there is always a good thermal monocular that will suit you perfectly.

However, any thermal monocular should meet several crucial criteria. Without them, the quality and functionality of the product significantly decrease. And as the price for such devices is not always small, you should aim for a good product, so you do not spend any money on a poorly working monocular.

We have created a detailed guide on how to choose the best thermal monocular. When looking for a good model, see if it meets the conditions described below and only then make your final decision on the purchase.

1. Battery Life

In the age of technologies, it is no secret that battery life is important. No electronic device is useful if it dies quickly, especially if you are planning to take it to the wild. The same thing is applied to thermal monoculars.

In general, the longer the battery life, the better. You do not want to be in the middle of nowhere without any device showing you some signs of life. Moreover, it would feel horrible to lose the track of an animal after a long chase.

Although the best thermal monoculars always have quite big battery life, they usually also include many different functions. We are not saying that a multi-functional thermal monocular is bad, however, those extra features might drain your battery much faster.

In these cases, choose the models that allow you to turn off these features. Otherwise, opt for the products where the functionality is just as minimal as you need.

2. Thermal Resolution

Thermal resolution is all about the quality of the picture you see on your screen. Good thermal monoculars translate a clear image with properly distinguished features of your target to the display. Thus, a thermal sensor resolution is one of the most important parameters that should be checked before the purchase.

Quite a good thermal sensor resolution starts from the range of 480 by 460 pixels. You will be able to see the picture properly, however, there are even better options. But if you do not have the fortune to spend on this hunting device, then such thermal sensor resolution should be enough.

3. Magnification

If you want to be able to see the prey even from long distances, make sure that your thermal monocular has proper magnification. Basically, it shows you how much you can zoom in on your picture and how good the quality stays.

There are some models that come with digital zoom and other advanced zooming options. They might cost a bit more, but if you are planning to shoot long-range, then those features can be very convenient.

4. Detection Range

Detection range is a crucial feature of any thermal monocular. It shows how far the thermal scanner can work and at what maximum distance it can detect any heat patterns. Of course, the bigger the detection range, the better.

Any handheld monocular that has a high detection range costs more than the devices with a shorter one. Depending on your amount of experience and the target you are aiming for, a big detection range can be either very useful or not necessary at all.

In general, it is always better to have a thermal monocular with a bigger detection range, especially if the budget allows it. You never know when you might suddenly need to follow an animal or watch it from far away.

5. Display Color Options

Any basic thermal monocular should have several display color options for you to choose from. Otherwise, you might not be able to see the target properly, even if you have an extra good thermal scanner.

Different color palettes allow you to see a different amount of heat and energy radiated from an animal. When one color combination might show a blurry picture with hardly distinguishable silhouettes, another one might give a perfectly clear and easy to grasp image.

Although, nowadays the majority of thermal monoculars come with at least three or four color palettes, there are still some companies who make the devices with one color combination only. It is done to make a cheaper product. However, the quality suffers from such an economy as well.

6. Size and Weight

Carrying a chunky and heavy device everywhere with you is really inconvenient. You do not want to add some extra weight to your firearm and hunting bag. A thermal monocular should have a small weight so that you can transport it easily.

Moreover, thermal monoculars that are made to be held in hand should not be too big. Otherwise, it will be uncomfortable to put it away quickly when needed or to use it during shooting.

7. Durability

Hunting is not an activity during which you can walk around carefully and gracefully. You are always on the go, with branches getting in your face and hard stones under your feet. If something falls, it should not break down easily.

The durability of a thermal monocular should be good enough to resist water and any external pressure. The weather can change quickly, and if your device is not waterproof, the hunting might end right there.

Also, pay attention to the quality of the thermal optics. The lense ideally should be made from scratch-resistant glass. If a lens cover comes in a package to protect the fragile part of your device, it is a benefit.

8. Price

We have already mentioned that the price for thermal monoculars is not low at all. While you might find some good affordable options, still, they are not as cheap as other shooting devices, for example.

Overall, the price should be rational. If there are only the basic features included, but the price is the same as for the multi-functional thermal optical device, then the purchase is probably not worth it. Look for the tools that have as many features as you need at a price that is not insanely high.

9. Some Extra Functions

Your thermal monocular does not have to be fancy and full of different features. Its main goal is to detect heat signatures and help you to shoot when visibility is poor. However, having some extra functions that can improve your hunting experience is always nice.

If you like video recording and you want to document your experience, then choose the monoculars that have internal memory or wireless connection to other devices. These features will allow you to save the filmed footage and then send it anywhere you like.

Some other great functions that one can sometimes see in these products are compass and range-finder. They are not always necessary, but it is good to have them just in case.

Choosing the Best Thermal Monocular

In our list of top-five thermal monoculars, we have included products that have excellent quality and top-tier functionality. If you do not want to spend time researching the market for a good option, you can safely pick one from the list.
