Things to Consider
Thermal binoculars come with many high-tech features, which equip them to perform tasks that regular binoculars wouldn’t do. To get the most out of your thermal binoculars, it’s important that you understand the features that give these eyepieces their unique capabilities. In this next section, we’ll touch on each important feature, tell you why it matters, and show you how to evaluate the specifications when buying thermal binoculars.
How thermal binoculars will improve your hunting
Thermal binoculars have a wider field of view, which gives you a better view of the target and the surrounding environment, in this way helping you plan and execute your hunt more effectively. And because these binoculars use digital magnification, the viewing angle does not change even when you adjust magnification. This reduces the amount of time it takes to focus on the animal and increases your chances of success at first shot.
Thermal binoculars also come with a rangefinder that accurately calculates the distance to the target and the best shooting angle, helping you take the best shot so that your ammunition is right on target and you don’t miss.
Because they rely on the heat emitted by animals to detect the location of the animals, they make it easy to spot prey and track its every movement.
You can use them to locate and get rid of predators that could interfere with your hunt.
You can use thermal binoculars both day and night, which increases the possibilities of where and when you can hunt.
Thermal binoculars are an expensive investment. Premium models sell for as high as $5,000-6,000, with lower-priced models going for about $1,500-2800, thereabouts. The more advanced the technology and the more features the binoculars have, the higher its price is going to be. But the possibilities of what they can help you achieve and their longevity make them worth every dollar.
Choose the best thermal binoculars by the following features
Here now are the features that you should consider when buying thermal binoculars. These features are what determine the performance of thermal binoculars.
The range of detection refers to the distance within which the lens can detect an object. The higher the range, the further the distance you can scout using the binoculars. Such binoculars are the best choice for long-range hunting or surveillance. If you’ll be using the binoculars for long-range viewing, consider thermal binoculars with a reach of 1,400+ yards. Pulsar thermal binoculars fall in this category. The Accolade XP50 and XQ38, for example, have a detection range of 2,000 yards.
Thermal binoculars with a high resolution have a higher pixel concentration and give a better image quality. The average resolution for high quality images in thermal binoculars is 640×280, and many binoculars will have this. Still, some have a lower resolution and others a much higher one. If you’re looking for exceptional contrast and image sharpener, go for a pair with a high resolution, like the ATN BINOX 4T 384, which has a resolution of 1280×720.
The viewing angle indicates how much you can see through the lens. A high viewing angle equals a wide field of view, which is crucial since you want to see far beyond just the object you’re targeting. You want to be able to see the immediate area surrounding the object, whether you’re hunting or exploring, and especially if scouring an area for safety, so binoculars with a high viewing angle are preferable. Some good choices with respect to this are ATN Binox 4T 640, which has a viewing angle of 12.5×9.7 degrees, and Pulsar XP50, which has a viewing angle of 12.5 degrees.
Color modes give better definition to images, and in turn, boost recognition and identification. A significant number of binoculars come with custom color modes that you can play around with for the best image quality. Pulsar thermal binoculars, like the XP50 and XQ38 discussed here, have 8 color modes. With such great variety in color settings, it’s easy to find a color mode that captures a clear and rich image in each environment. On the other hand, ATN Binox 4T binoculars have black and white settings, as well as color modes to boost image quality. Black reflects cool colors while white reflects warm colors, and this option works great where identifying color distribution on an object is not important.
The magnification power of the binoculars determines the extent to which you can enlarge the image of your target. A high magnification power allows you to get a large image of objects that are far and minuscule when seen through the lens. You need this when aiming a shot at prey, for instance, or when sightseeing. Fortunately, thermal binoculars have a magnification range that works for both short and long distances, and which you can adjust as needed for different detection ranges. This can be anywhere from 2.5-25x or more.
For an item that costs thousands of dollars, you would expect to have a long guarantee period, probably even a lifetime warranty. But no, on average, thermal binoculars have a surprisingly short warranty period. Pulsar, which is one of the top thermal binocular’s brands, guarantees its binoculars for only 3 years. For some models, the warranty details aren’t indicated on the product details that are available to the public. If this applies to a binocular model, you’re interested in buying, be sure to inquire about the product guarantee from the seller or manufacturer so you know what the deal is before spending your money and getting stuck with the product.
For convenience, most thermal binoculars come with rechargeable batteries that you can charge by connecting to a power source via USB. Often, you can use a power bank for this when in the outdoors. Batteries last at least 7 hours, with the best of them running for up to 16 hours even with Wi-Fi use. With the latter, this means you can cover a whole day of adventures without recharging the battery or worrying about skipping some bits because of low battery power. As an example, Pulsar thermal binoculars battery packs have a 7-hour runtime, while the ATN Binox 4T series has 15-16 hours in battery life. See, there is variety. Just pick according to your requirements. It’s always a good idea to carry a spare pack of batteries. This way, you can just replace the flat battery instead of waiting for it to recharge.
Dimensions and weight
Thermal binoculars average about 2 pounds in weight, with some weighing less and others more. For example, ATN Binox 4T binoculars weigh 2.5 pounds, while the Accolade XP50 from Pulsar weighs 3 pounds. If you’re going to be mounting your binoculars on a weapon or stand most of the time, you can get away with a heavier set. If, on the contrary, you’ll be holding the binoculars in your hands most of the time, you need a lighter model that will not wear you out. The Pulsar Accolade XQ38, at 1.3 pounds, is very lightweight and a good example of such binoculars.
Similarly, the binoculars need to be compact enough for you to carry with ease. Check the dimensions to make sure that you’re comfortable with the size of the binoculars. Again, if you’ll be mounting your binoculars on something most of the time, you can get away with a bulky pair. But if you’re relying on your hands to carry and support the binoculars, a small design is preferable.
To ensure that your outdoor activities are not limited to certain weather conditions only, choose weather proof binoculars. Check the rating because this is what indicates how much exposure to extreme weather the binoculars can withstand. Overall, you should be able to use the binoculars in wet weather, when it’s drizzling, snowing, in foggy weather, and when the humidity is high. Both the Accolade and ATN 4T series are weather resistant, for example, but the rating and what they are shielded against may differ. An IPX7 waterproof rating, like in the Pulsar models, means the binoculars are submersible up to 1 meter for a maximum of 30 minutes. Leave them in the water any longer or drop them in water that is deeper than a meter and they may be permanently ruined.
Video- and photo-recording options
Most thermal binoculars come with a built-in video and photo recording feature that you can use to record your adventures in video or picture form. A good number of such binoculars support micro SD card storage, so you simply insert a micro SD card and the recordings are automatically stored there. Non-SD card-compatible thermal binoculars may support USB storage. This type is more involving because you have to connect a USB storage device to the binoculars to record events. Depending on where you are and your setup, this can be a little inconveniencing, but it is doable.
Many video settings on thermal binoculars also support live steaming and sharing of files. They do this via a simple Wi-Fi streaming function, as applies to the ATN Binox 4T binoculars or through applications like the Stream Vision app, which is compatible with Pulsar Accolade thermal binoculars. Usually, you can stream and share the content as it records, practically killing two birds with one stone.
While thermal binoculars and monocular are similar in design and principle, each is suited for different applications. Thermal binoculars are best used for events that require long viewing and/or a wide field of view, such as hunting, sports, sky and marine watching, and scouting. By contrast, monoculars are a better option for events that don’t require a wide field of view or observing for long periods. You can use them for golf, hiking, bird watching, and to spot targets when using long-distance rifles. Using monoculars for extended viewing strains the eyes because you’re using only one eye to view. The upside to this is that monoculars make a great scouting tool for night vision because when you’re only engaging one eye in looking through the lens, your eyes adjust to the ambient light faster than when you’re using binoculars.
In most aspects, it is. Unlike night vision, thermal imaging does not rely on light to detect a target. Rather, it uses radiation to detect heat, and because living targets emit heat, it becomes easy for the sensor to identify locations where there’s greater heat concentration. With night vision, if there is no light, the apparatus can’t identify a target. When using night vision, the target can see you, again, because of the light aspect. Thermal imaging, by contrast, is discreet and because the apparatus is not emitting any rays or identifiable compounds, the target cannot see you, which makes it perfect for both hunting and surveillance. While thermal imaging is used day and night, night vision is limited to nighttime use because the intense daytime light filtration would damage it. The only aspect where night vision is better than thermal imaging is facial recognition, where it produces more detailed images than thermal imaging.
Infrared vision uses short wavelength infrared light to highlight the target area, and then reflects back the image for interpretation. If compounds like fog, dust, other types of light, etc. interrupt the transmission of infrared light, the reflection is compromised and the integrity of the image distorted. In this way, infrared technology is less reliable in certain situations. Thermal imaging, on the other hand, uses mid and long wavelength infrared energy, not light, to sense heat changes in the environment. It then transmits these heat signatures to a monitor, where they are interpreted (in black and white) into an image. Compounds like light, fog, dust, smoke, etc. do not have an impact on thermal energy, which makes thermal imaging reliable in a wide range of conditions.
Our Editor’s Choice is ATN Binox 4T 640, which we like because of its precise target locator features, among them powerful sensors, a laser rangefinder, and a custom e-compass. Great image quality, a wide viewing angle, full HD video recording, and a long-lasting battery are its other winning features.
Our second choice is ATN BINOX 4T 384, whose high resolution yields crisp clear images with great definition. An integrated laser rangefinder gives precision ranging, and a built-in IR illuminator optimizes it for night vision. It is a micro SD card- and smart device compatible. It’s also weather-resistant and perfect for all-season use.
Our third choice for the best thermal binoculars is Pulsar Accolade XQ38. The IPX7 waterproof rating makes them ideal for use in any weather condition, and the high-contrast AMOLED display ensures clear and detailed images. The included battery pack provides plenty of power for extended use, and the 3-year manufacturer’s warranty gives you peace of mind.
