Thermal binoculars allow you to see wildlife (and humans) after dark by sensing the heat of their body. They differ from typical binoculars, which rely on light transmission into the eyepiece, but both types of binoculars can be very useful, particularly when birdwatching and nature-watching.
Two different types of technology allow you to see in the dark: night vision and thermal imaging. Night vision binoculars require a small amount of light in order to work, which is then amplified to allow us to see. Thermal imaging, on the other hand, detects heat, which is then displayed using color-coded imagery.
In this guide, we have compiled the best thermal imaging binoculars currently on the market to help you make the best investment. There's no denying that thermal binoculars are an expensive bit of kit, but with Prime Day coming up on July 8-11, you might be able to bag a discount. The models we've listed in this guide range from around $1,500 to $4,999.
As with any purchase, there are myriad things to consider, like whether the binoculars are waterproof, how much magnification they offer and whether they need batteries. Our list answers these questions, giving you a clearer idea of what thermal binoculars to buy.

Best thermal binoculars: Frequently Asked Questions
What are the best thermal binoculars?
In our opinion, based on our extensive testing, the ATN BINOX 4T 384x288 1.25- 5x smart HD thermal binoculars are currently the ones to beat.
Are thermal binoculars worth it?
With the improvements in technology and the advent of dual-spectrum capability, thermal binoculars are definitely something to be considered, especially if you want to observe subjects in the dark.
What should I look for in thermal binoculars?
Is the thermal device equipped with an expansive screen that boasts a high display resolution, allowing for effective upscaling of thermal images? Does the display feature a rapid refresh rate for smoother visuals? Is the thermal unit designed with a replaceable battery for extended usability?
Is night vision or thermal better?
More and more, we are seeing these two technologies merging into one unit. The difference is that thermal binoculars can see in complete darkness, whereas night vision relies on amplifying existing light.
Can thermal binoculars see through trees?
No, but if an animal or target is behind a tree, it wouldn't take long for the thermal to pick up the heat source as the animal moves around the trunk.
What is the cheapest thermal binocular?
We have chosen the AGM Global Vision ObservIR CMOS 5.5-22x25mm as the best budget thermal binocular. The technology in these binoculars is not cheap, so you'll struggle to find a pair that are truly budget-friendly and still work as well as intended.
Do thermal binoculars work in the day time?
Yes, most thermal binoculars should still work as intended during daylight hours. They work by picking up on heat rather than light, so it doesn't matter if it's light or dark.
Can thermal binoculars see through walls?
No, thermal binoculars can't see through walls or other solid structures. However, if there are heat sources within the walls, such as pipes with hot or cold water flow, they'll likely be able to pick up on that.
Do I need high magnification on thermal binoculars?
High magnification will allow you to see farther, so the magnification you need will depend on your intended use. Even low magnification thermal binoculars will allow you to see heat signatures, but they are best for close-range viewing.
What are the best waterproof thermal binoculars?
We think the best waterproof thermal binocular is the Pulsar Merger XP50 LRF. These binoculars are IPX7 rated so can be immersed in up to 1m of water. They're also hard-wearing and protected against other weather conditions.

Future updates to this guide will be detailed here.
How we test the best thermal binoculars
We test all of our optics by taking them into the field in all weathers and in day and night. We also unbox and examine the body and features to make a concise record of these things.
Each pair of binoculars is carefully tested by either our expert staff or knowledgeable freelance contributors who know their subject areas in depth. This ensures our reviews are backed up by personal, hands-on experience with each binocular, and that each pair is judged based on its particular price point, product class and intended use.
We look at how easy they are to operate, whether eye relief can be adjusted for spectacle wearers, whether a binocular comes with appropriate accessories or carry bags, and also make suggestions if a particular set of binoculars would benefit from any additional kit to give you the best viewing experience possible.
