9 Best Thermal Imaging Binoculars and Bi-Oculars for Hunting

  • By: Michaela King

There is often confusion between thermal imaging devices and night vision devices, despite both being instrumental in allowing us to see what is not visible to the naked eye. However, there are significant differences between these two technologies. To address this common misconception, I have compiled a list of the top 9 thermal imaging binoculars and bi-oculars for hunting, providing answers to your queries regarding these devices.

Firstly, let me clarify the concept of thermal imaging:

The sun emits radiation, and objects, plants, and animals absorb and reflect a portion of this radiation. Our eyes can only perceive the reflected light, which means that without sunlight, we are unable to see anything. The range of light that falls within our visible perception is referred to as the visible spectrum, which is commonly remembered through the acronym VIBGYOR.

However, beyond the visible spectrum lies infrared radiation, which is invisible to us. To detect and visualize this infrared radiation, specialized sensors are required. This is where thermal imaging and night vision optics come into play. Night vision optics amplify the minimal available light to provide a clearer image, while thermal imaging optics capture the infrared heat emitted by objects.

With thermal imaging optics, you can observe objects in the absence of visible light, enabling you to identify your target or desired object. Initially developed for military use, thermal optics have gained popularity in the hunting community. As a result, there is now a diverse range of thermal optics available specifically designed for hunting purposes.

To assist you further, I have curated a collection of the nine best thermal imaging binoculars and bi-oculars. Together, let us delve deeper into the features and capabilities of these devices.

How to choose thermal imaging binoculars?

As I said earlier, thermal imaging optics are relatively new in the market; people don’t know much about their specs. Now that you are looking for best thermal binoculars/bi-oculars for hunting, here’re the essential features your thermal optics must have:

Thermal Resolution

Cameras which click bright pictures always have the edge over competitors; same goes for the thermal imaging binos. If they offer better image differentiation and the imagery is bright, you should prefer them.

Pixel size

Pictures are made up of small bits, called pixels. If an image has many pixels, its quality would be better, and you could zoom in to find out more detail. The binoculars which offer more pixels per view are great for hunters (and of course all other activities too).

Frame rate

When we press the button of our camera, and it clicks an image, that’s called frame/refresh rate. It’s slightly different in thermal binos. Let’s say you are running behind an animal, the sensors of your thermal imaging binos will turn the infrared radiation into a picture and then show it to you; if this process takes time, you’ll miss your target. To avoid this, you should opt for binos which offer high frame rate.

Detection range

All that amazing frame rate and a large number of pixels go in vain if you cannot cover a significant distance. Before getting a pair of thermal binoculars, know the detection range they offer (remember it’s different from the regular binoculars).  For hunting, a detection range of more than 1 mile would work fine.

Price range

And last comes the price; shortlist the pairs which have your desired features and compare their price range. Do not miss an amazing pair because it’s costly, if you do so, you’ll miss out the real fun of hunting in zero to minimal light.

Tips for thermal imaging binoculars and bi-oculars

As we know, thermal devices are complicated and fragile; if you mishandle them, you are going to regret big time. To avoid any troubles related to your thermal device, follow these tips:

No, you can’t do it yourself

We all are very impressed with those DIY cleaning and repairing videos which YouTube keep recommending us. But when it comes to sensitive gadgetry, STAY AWAY.

Yes, do not think you are a certified technician who can open up those delicate parts, clean them, and place them back just because you have watched a video.

Lenses, eyepieces, illuminator, and microphones, in fact, all parts of thermal imaging optics are sensitive, which should be handled with care. So if you have plans to repair your thermal device at home, forget them.

Protect them

Although most of these optics are shock and weather-resistant, taking care of them is mandatory. Protect them from colliding against hard surfaces, falling in the water and strong in damp or dusty places. Just remember that you’ve spent a lot on this gadget, it will help you in being extremely careful with it.

Frequently Asked Questions

Q. What is the difference between binocular and bi-ocular?

In a binocular, there are two lenses which receive sunlight. When you need to see something up close, you pick the binocular and place it in front of your both eyes. Which means a binocular has two lenses and two eyepieces. The lenses collect brightness, and the eyepieces are those holes where you place your eyes.

But in a bi-ocular, there is only one lens. There is a place for both eyes, but the source which collects light i.e., the lens, is only one.

Hunters prefer bi-oculars over binoculars because these are pretty handy and easy to carry. But, for more secret missions, and exotic hunts, binoculars have the edge over bi-ocular due to the brighter imagery they provide.

Q. Thermal imaging basics (what is thermal imaging)

Sun emits two types of light, infrared and visible. The visible light comes to us in the form of seven colours i.e., the visible spectrum because the objects reflect back these seven colours i.e., VIBGYOR. But we cannot see the infrared light as the objects do not reflect it back.

But, the thermal imaging optics record that invisible light and make it visible to our eyes. Let’s say an animal is moving in the dark; the thermal imaging optics record the heat which the animal’s movement produces and show it to us as a thermographic image. The thermal image we get to see is of various colours mostly red, yellow, black, and white, depending upon the intensity of heat an object emits.

Q. Thermal imaging for hunting – purpose and best practices

Hunters are probably the most challenge-loving people around us. They do not dread the fast moving, and powerful animals and go out to hunt them down. But the biggest hurdle which might put them in danger is the darkness. When it is night time, and someone is wandering around in a jungle, the only way for him to see the surroundings is thermal imaging.

The thermal optics records heat that different objects emit, and when the hunter sees the recorded image, he can find out where his target is and what path should he follow. Most of these thermal optics offer Wi-Fi adaptability so that if you are with a group of hunters, you stay connected with them.

Q. Why are thermal imaging devices so expensive?

There are two reasons behind the steep pricing of thermal imaging optics:

The materials

Most thermal imaging lenses are made up of germanium, a rare and costly metal. Generally, 1kg germanium costs 1500$ to the optics company, and when refining and crafting methods which turn germanium into a lens are combined, the price further rises.

The technology

The regular binoculars and monoculars are common now, one can easily get them from numerous brands. But thermal imaging is a very advanced technology which requires specialized techniques for turning the invisible light to visible one.

The microbolometers, internal memory, gyroscopes, illuminators, and various sophisticated techniques are hard to find, and when you do, they leave a large hole in your pocket.

Q. Can thermal imaging see through walls?

No, they cannot. Let’s say you focus on a house with your thermal binocular, the image it generates will be of the outer wall itself, and not of the things inside. All objects generate heat i.e., trees, walls, water, grass, sand, etc.; we can decipher the type of object in complete darkness with a thermal binocular, but we cannot see beyond those objects.

Same goes for the hurdles present between a hunter and his prey; if there is a tree between the two, the hunter will only see the tree’s infrared radiation.

Q. How thermal imaging works?

Every object, living being, and commodity present on this earth radiates some amount of heat, but we cannot see it with our bare eyes. If we wish to see the objects in darkness, we must record the amount and pattern of heat they radiate.

The thermal imaging optics do that errand for us and bring out a comprehensible image of heat an object emits. For example, if you’ve strayed from your path in a jungle and have no source of light, but you have a thermal imaging device, you can come out safely.

Law enforcement agencies use thermographic images to catch the out of sight suspects and identifying the type of crop being cultivated (as all crops have distinct heat emitting range).

Q. How to read thermal imaging?

When the thermal imaging device curates an image for you, the next step is to decipher what is in front of you. As thermal imaging works when there is heat, the colours which these thermograms show depend upon the amount of heat any object emit; moving objects radiate more heat than the calm ones.

Thermal images used to be in two shades at the beginning i.e., black and white. The white areas represent objects which emit the higher amount of heat, while the black areas show the calmer objects. For example, when you are hunting, the trees present in your way will appear as black, and the animals, birds and moving water will appear as white.

Now, most thermal imaging devices use colour schemes to show heat patterns. Four primary colours used in these thermograms are red, orange, yellow, and purple.

Red colour means the highest heat; if an animal is running, it will emit red light. Then comes orange, which is slightly lesser in the heat than red, such as windy leaves.

Water being a cold surface appears as a purple, and if it’s moving, it will be yellow.

Note: this description of colours is for the hunting environment only if your physical surroundings are different, you will have to determine the types of objects accordingly.

Q. What is thermal imaging used for?

Thermal optics became popular after Boston marathon bombings. In 2013, the police caught a Boston bombings perpetrator hiding in a boat with the help of thermal imaging scope mounted on a surveillance helicopter.

Since then, all optics companies are working to develop state-of-the-art thermal optics, and people are incorporating their usage in all fields. Here are some top areas where we can use thermal imaging optics:

  • Firefighters use this to detect the intensity of the fire
  • For checking the water and gas leakages in the buildings (as they catch the difference in heat)
  • Surveillance of jails when it’s dark
  • Hunting wild animals
  • Spying
  • Border security
  • Detecting indoor marijuana cultivations

Q. What blocks thermal imaging?

Although it is almost impossible to dodge the sharp sensors of thermal optics, there are still a few ways to decrease their detection capacity.

Firstly, glass doesn’t reflect the light back, it absorbs it. If one wishes to see what’s behind a glass window with thermal imaging binocular, it’s complicated.

Hard surfaces like trees, walls, rocks, and thick bushes all block the thermal imaging, and if a person or game is hiding behind these objects, you cannot detect them.

Bare skin radiates more infrared light as compared to the one covered with cloths. Full body woollen suits, blankets, and shawls, all blocks the thermal imaging; but they start becoming weak once their temperature matches with the body’s temperature.

Final words

These 9 best thermal binoculars and bi-oculars for hunting which I have reviewed are state-of-the-art devices. If you have plans to enjoy night hunts, thermal imaging optics should be on the top of your wish list.

So, now that you have come this far with me, you must know that detection range, detector pitch, and refresh rate are three essential features we must remember while picking up a thermal imaging device.

Having said that, here are my 3 most favourite devices from the above list:

Pulsar XP50 binocular is for those who do have a deep pocket and want to enjoy the thrill of night hunting. This binocular is a bit expensive, however, it’s extremely robust and compatible with harsh environments.

Armasight Command 3-12×50 Thermal Imaging Bi-Ocular is a multipurpose device with 3 years warranty, large lens, eye-relief distance and incredible thermal resolution of 336×256, and its 60 Hz refresh rate works as a cherry on top.

If your budget is limited and there is not an exotic hunting expedition coming your way, then you should go for Yukon 1×24 goggles, which has all perks of thermal imaging binoculars and will not cost you an arm and a leg.

Thermal imaging devices are the latest “in” thing; if you love adventures, these devices are perfect for you.

So, I tried my best to answer all probes related to this newest technique, and I am sure your confusions are now gone. Greetings!
