There is a common confuse between thermal imaging and night vision devices. Although both devices are used for aiding night vision, there are various differences between the two. In this article, we are going to look at some of the thermal imaging binoculars and bi-oculars for hunting.
First, what is thermal imaging? The sun emits heat which is absorbed by objects which they reflect some of it. Our eyes cannot see the infrared radiation emitted by objects, and that is why need specialised sensors. This is where thermal imaging devices come in. They enable the user to detect animals even when there is pitch darkness.
Night vision optics enhances minimal light present to provide an image while thermal imaging devices capture the infrared radiation emitted by objects. This is the main difference between the two.
Here are some of the best thermal imaging binoculars and bi-oculars
i. FLIR BHS-XR Command 640×480 thermal bi-ocular

Another standing out feature is the 50Hz refresh rate. This will enable you to aim and hunt fast-moving animals.
How to choose thermal imaging binoculars and bi-oculars
- Thermal resolution
Some binoculars and bi-oculars have the edge over others in terms of thermal resolution. If you want to get clear images, you should choose a device with high resolution.
- Pixel size
A picture is made of small bits known as pixels. If there are more pixels, the image will be of high quality, and you can zoom in to get more details. So, a device with more pixels per view will produce better images and can be used in a wide range of applications.
- Refresh rate
This is the rate at which the device takes to refresh the image. If the device has a low refresh rate, it will take some time to display the image. Therefore, it is good to choose devices with a high refresh rate.
Since thermal imaging technology is still new, it is very difficult to find the right binocular or bi-ocular. We have reviewed some of the best thermal imaging devices on the market. Our top pick is the FLIR BHS-XR Command thermal imaging binocular because of its grander features. Although it is a bit pricey, it is extremely robust and can use even harsh weather conditions and environments.
