Going into the process of purchasing a handheld thermal imager blindly isn’t desirable. Naturally, there are a couple of factors and features that people should be aware of beforehand. In this guide, we’ll talk about the qualities of the best handheld thermal imager as well as some characteristics that buyers should pay attention to so that they won’t be fooled.
Users should be able to get clear visuals even though the subject they’re observing is distanced and far from their standpoint. This is enabled thanks to a thermal imager’s magnification. In other words, this feature will dictate how much a user can zoom in on the subject.
This capability of a handheld thermal imager can even be often seen in the actual name of the model. To illustrate, if there are two numbers separated by an x in the model’s name, the first one usually suggests the magnification powers of the model. The second one refers to the objective lens diameter.
Toughness and Durability
Thermal optics can be a real investment when it comes to the amount of cash one can spend on some models. So, it’s only natural for users to want the products they buy to be sturdy and tough. These models can withstand even the harshest weather conditions and can perform well no matter the surroundings the users can find themselves in.
To achieve toughness, manufacturers make their models waterproof, fog proof, resistant to external conditions, and similar. All of this makes the thermal monocular increasingly long-lasting, which is another aspect we’ll briefly cover in a second.
Besides being tough, users want to use their models for a long time after the original purchase. To last that long, models have to resist shocks, pressure, and all other types of external conditions. Even though they tend to be pricier, durable models serve the user for many days to come. That way they can even save some money that users will spend on buying another monocular once a short-lasting model quickly breaks down.
When we say that a thermal imager is compact, we usually refer to its lightness as well as the small size. When it comes to handheld models, this is very important because, as the name suggests, users can hold them in their hands for as long as the observational activity lasts. Thus, if a model is heavier and bigger, the buyer won’t be able to hold the model in their hand.
Additionally, compact models are great for transportation and taking them with you when you’re traveling. Also, you can easily store them when you’re temporarily not using them.
If there is nothing to power up the model, no matter what kinds of specifications the model has, it will still be in vain. It may be surprising to some that there are models that are easily running out of power. Indeed that’s true. So, people should watch out for models like that and instead try their best to find a product that has longer battery life.
Aside from this, you should be mindful of the number of batteries that are required and their type. That way you’ll know which ones to get. It’s even better for some users if they’re rechargeable. This means that the thermal imager won’t run out of power as long as you come close to a source to charge the batteries with. Moreover, you won’t be required to spend more money on purchasing spare batteries to take with you.
Traditionally, the role of the handheld thermal imagers is to observe subjects as an integral part of a profession or an outdoor activity that the user does as a hobby. However, as users’ needs and preferences evolved together with the rapid development of technology, the thermal imagers changed, too.
For one, some models have recording features that enable users to capture images and record videos of what they’re seeing through the lenses. Later, this visual material can be stored on microcards and shared on smartphones for later usage.
Some imagers can connect to the Internet. Thanks to Wi-Fi they can enable an easier transfer of the before-mentioned pictures and videos. Also, they can stream videos on online video platforms because of it.
A built-in rangefinder represents another additional feature of many thermal monoculars. Its task is to measure the distance between the model and the subject. Smart rangefinders can do all the calculations on their own. So, hunters can get the required shot if the thermal imager is utilized for this purpose. Subsequently, when such a device is built into the model’s design, users don’t have to purchase an additional rangefinder. Plus, their hands will be less full because they can just carry with them a thermal imager with a built-in rangefinder instead of having the two separate devices in their hands.
Frequently Asked Questions (FAQs)
Answer: Thermal technology is using the heat that is emitted from subjects to generate a heat image or a map of the subject. That is achieved thanks to infrared and thermal energy. With that being said, it’s a slightly newer type of technology when compared to simple night vision. On the other hand, night vision technology depends on the light as well as how strongly a source emits the light.
Answer: Even though thermal imagers can be categorized in numerous ways, one of the main ones is a head mount thermal imagers, as well as handheld thermal imagers, that we talked about today. As the name suggests, the former imagers are attached to a helmet or other types of headgear. The handheld imagers are made for holding in the hand.
Answer: These thermal imagers have a great performance in a wide variety of outdoor activities – from hunting to surveillance and everything in between. Some experts think that generally, they’re great for hunting and wildlife observation. That’s partly the case because these models are increasingly light and small so users can easily hide and not give away their position while at the same time be able to get a great shot or simply quietly observe. However, this is mainly up to the particular model and its specific features. That’s why it’s best to consult with the user’s manual that you get with the purchase for all of these details and more or ask the manufacturer of the particular model.
After all of this, it can be concluded that handheld thermal imagers are useful additions. Starting from the fact that they are compact and can be held in the hands for a longer time up to their capabilities to detect temperature changes, they offer support while doing repairs at home or enjoying a hunting trip in nature. However, before deciding which thermal imager to purchase, users should focus on certain details. We covered the main ones before together with free reviews of the top brands and models.
