The Best Thermal Imaging for Hunting – Top Picks and Reviews

It’s not easy at all to hunt at night or in tough surroundings where not all animals are visible at once. This is why people are constantly looking for thermal imaging for hunting. That way whenever an animal crosses their view they can easily spot it and act accordingly. Unlike the regular optics which showcase the views in colors or black and white at night, these ones are able to read the body temperature and point the location of a living creature right away. In many instances, they can do this regardless of the obstacles that may appear between the hunter and the target.

The fact that this hobby is legal in many states makes the need for proper thermal imaging even greater. Luckily, there are plenty of models of monoculars, rifle scopes, cameras, and other imagers available on the market. All you should do is to come across the right ones for you. To give you a hand with this matter, in the following paragraphs, we’ll present some of the top models together with a guide for buyers.

Identifying 6 rights before you have it

Resolution of Images

Naturally, the image resolution is different when it comes to basic models and high-end ones. Further, the former cost less and have a smaller resolution. On the other hand, the latter option has a higher price yet the resolution is also bigger.

Both thermal imaging pieces of equipment can be used for the same thing. However, there are some important differences. The pricier models are way better at detecting animals when they’re far away from where you’re standing. Also, they’re better at separating objects from actual animals.


Thermal imaging optics are known for possessing a digital zoom. Still, the magnification capabilities may cause some disruptions and can sometimes even confuse users about which model is best.

It’s recommended to look for imagers that have a bigger objective lens and native magnification powers. That’s usually the case because this type of magnification provides more clarity. And the visuals appear less grainy. As you surely know, when you use the magnification too much, the image you’re seeing is pixelated, which means that small squares appear. This can negatively influence the quality of the image. This situation is especially noticeable when it comes to basic models.

That’s why many people suggest going for a higher resolution and lower magnification.

Black and White vs. Full Color

If the user sees colors or just black and white images while looking through the thermal imagers is also another factor to consider. While it may not be at the top of the list of priorities, it’s still worth deciding which one suits you better.

It’s widely regarded that users see more easily with black-and-white imagers. These tend to be less expensive, too. These models usually are known for higher resolutions. However, they’re unable to perceive ranges of the temperature of the subject that the user is observing.
On the other hand, the full-color ones can do that. But, a higher price may be written on their price tag. Still, it’s up to the personal preferences of each buyer.

Refresh Rate

For those who aren’t entirely familiar with the term, it signifies how frequently the image refreshes. A higher rate means that users get a more precise image and the whole experience is smoother. In turn, this capability can increase the price of the model.

Some agree that a refresh rate of around thirty hertz or something north of that. This allows users to easily follow a subject and get flowing visuals.

Battery Life

The battery life of the thermal imager is largely determined by how much it’s used. This is an important feature because it can seriously limit the user and the way they utilize the model. This is especially the case if you find yourself on a wide field or on a mountain without a power source. So, it goes without saying that buyers typically look for longer battery life so they can operate with the imager for a long time without having to recharge the battery every so often.

What’s more, it’s considered that the battery lasts for about eight hours on average. Usually, this is characteristic of the more expensive models. Generally speaking, battery life from eight to twelve hours is pretty much standard.

However, this doesn’t have to be a make-it-or-break-it moment. Some models have battery trays for extra batteries. Also, external batteries are becoming a common thing in the field. These batteries can significantly increase the period of usage.

The Product’s Warranty and Customer Service

Sometimes when two imagers are very much alike, details, which may appear small at the beginning, can make all the difference. What we’re talking about is the warranty period. Brands have different warranty periods among themselves, so it’s in your interest to look for models with a longer period. This means that if something happens to the product, you know that you can rely on the company to fix the issue even several years after the original purchase.

Closely connected to the company’s warranty policy is the customer service. At first glance, you may not see the correlation between a thermal imager and the customer service of the company that made it and sells it. However, something will happen to the product eventually. And you will definitely like the company to take care of the issue and treat you respectfully, instead of it being dismissive about it.

Frequently Asked Questions (FAQs)

1) How does thermal imaging work?

Answer: In order to come up with images of subjects, thermal imaging, as a method, uses thermal energy, as well as infrared. Using these two, imagers that use this method get all the information that’s needed to form an image, which a user finally receives. This can happen even during low-light conditions and in surroundings with a lower source of light. It’s still considered to be a contemporary and newer technology. However, it’s risen to prominence quickly over the past period and is used for numerous activities among which is, of course, hunting.

2) How much does thermal imaging cost on average?

Answer: This is a pretty subjective question that depends on the particular model, its features and specifications, the manufacturer, and more. Still, it’s claimed that imagers can cost from a hundred dollars to three thousand dollars and more. Naturally, the pricier models offer premium features for an enhanced observational experience. Yet, users can find decent models with great performance at more affordable prices. So, attaching yourself to the most expensive model you can possibly find doesn’t sound like a great idea if you previously haven’t assessed all the available options for getting a reliable thermal imager.

3) Can I see through walls with a thermal imager?

Answer: Not exactly. Thermal cameras, for one, can detect the temperature that’s emitted from a subject. So, even though you can precisely see through walls, you can still pretty much find out some sensitive information that can be useful to you regarding what’s happening beyond the wall.

Final words

Having all of these things in mind, it can be said with certainty that thermal imaging is helpful while hunting. Rather than providing the traditional views that lack more thorough details, they enable shooters to see where their targets are based on body temperature. Of course, there are many details that make this possible, starting from the magnification and screens up to the options to capture photos and videos and store them.

Moreover, these are largely dependent on the type of thermal imaging device and its capabilities. For this reason, before making the purchase, you should stop for a bit and think about what you want from your imager in the first place. We hope we assisted you with this.

Finally, it’s time to hear from you. Where do you stand on this matter? Which thermal imager are you getting? Share your hunting experiences with these devices and your opinions in the comments.
