ATN BinoX 4T 384-4.5-18X Thermal Binoculars: A Detailed Review

Although thermal rifle scopes are fantastic, they can get unwieldy when you’re using your entire setup to scan fields for targets. That’s where thermal binoculars come in, giving you the ability to utilize all the pros of thermal vision without having to use your entire gun to look around. Not only are good thermal binoculars safer for glassing than using a thermal rifle scope, but they’re also simpler. The ATN BinoX 4T 384-4.5-18X thermal binoculars are one such option, and we’ve been using it in the field to find out just how it works. Here’s what we learned.

What’s the ATN BinoX 4T 4.5-18X Thermal Binocular?

The ATN BinoX 4T 4.5-18X Thermal Binocular is the company’s answer to the need for a portable thermal device that isn’t limited to monocular vision. This type of binocular is useful not only for hunters who want a separate set of binos to scan fields rather than using the thermal rifle scope mounted to their gun, but thermal binoculars are also great for spotting and tracking approaching hunting targets. Whether you’re hunting feral hogs, coyotes, or bobcats, thermal binos aren’t just a handy tool; they’re a must.

Specifications of the ATN BinoX 4T 4.5-18X Thermal Binocular

These are relatively large binos, but not excessively so. They measure 9.4 inches by 5.0 inches by 2.6 inches and weigh about 2.5 pounds. They’re also more than just thermal. The ATN BinoX 4T 4.5-18X Thermal Binocular is a Smart Ultra HD Day/Night Vision Binocular with a built-in laser rangefinder. The binos utilize 4K Ultra HD technology for improved image quality and has a Dual-Core Processor for the same purpose.

The binos have a 40mm objective lens and eye relief between 10mm and 30mm. The field of view at 1000 yards is approximately 220 feet, and the angle of view is six degrees. Magnification is 4.5-18X, as the name suggests, and the focus range is 10 feet to infinity (according to ATN). These binos are designed to be weather resistant and to remain operational in temperatures ranging from 20 degrees below zero to 120 degrees Fahrenheit. Micro SD cards from 4GB to 64 GB can be used to store images. These binos are charged with a USB-C cord, which is included, and have a stated 16-hour battery life.

Performance Features

Features of the ATN BinoX 4T 4.5-18X Thermal Binoculars include Bluetooth capability, a 3D accelerometer, a 3D gyroscope, a 3D magnetometer, and an E-barometer. The binos have a smart range finder, e-compass, and smooth zoom.

This device is also compatible with ATN’s Ballistic Information Exchange, which is technology ATN Smart HD-enabled devices can use to communicate. That’s useful because it can help you range targets and determine holdovers. This is where having one person with the binos and another with a rifle makes good sense because as long as the binos and rifle scope are ATN Smart HD equipped, they can make communicating a lot easier. Regarding video capability, the binos record in 1080p at 120 fps. It’s also possible to record to the Micro SD card in the binos while simultaneously live streaming to another device using WiFi. These binos offer a lot, to the point reading the manual is a good choice.

How do the ATN BinoX 4T 4.5-18X Thermal Binoculars work in the field?

The binos do take some time to charge before they can be used, and I ended up leaving them plugged in overnight. You feel the bulk of the binos when you pick them up, but not to the point that it’s unpleasant or difficult to hold them up for extended periods of time. They work best on clear nights, which is standard for thermal. Eye relief for my use required my eyes to be right at the eyepieces. Any adjustments I needed to make were fast and simple once I’d familiarized myself with the buttons.

When it came to game identification, distance and weather mattered. At a distance of 1,000 yards, it was possible to see the heat signatures, but it was difficult to determine what exactly I was looking at. Within approximately 350 yards, I could identify a large bobcat and a number of deer and feral hogs. When I was around 500 yards from the bobcat, I could see enough to be somewhat sure it was a bobcat but not sure enough to take a shot until I managed to close the distance more. At a distance of 100 yards and closer, it’s easy to identify your targets.

Cold Weather Performance

Some thermals with internal batteries experience a rather rapid decline in battery power when it’s cold out, but that doesn’t seem to be a real problem with these binoculars. Sub-freezing temperatures did cause a slight reduction in clarity, but those nights also usually had cloud cover or simply not much ambient light. The times the thermal binos didn’t seem to appreciate the weather was during rain. Even a steady drizzle caused fuzziness, but that is fairly common with thermal in general—it’s definitely not unique to ATN or to these binos.

The straightforward buttons were great because they made it easy to make adjustments without taking my eyes off the potential target. There’s no big learning curve to getting used to the button placement, either—I had them figured out the first night I used them. The binos were great for glassing fields at night and a lot simpler than using my rifle with its thermal scope (not to mention technically safer). When I was hunting with a partner, we were able to keep an eye on things, whether we had one rifle or two.

Should you get ATN BinoX 4T 4.5-18X Thermal Binoculars?

These thermal binos perform within their price point. They also handle target identification well within a reasonable distance. Interestingly, they could make out the racks on bucks at night when the buck would turn its head. You’d see the antlers flicker into being, then disappear again. These were late-season bucks well out of velvet. The moral of the story there is to take the time to get a good visual on your target rather than simply trusting a quick glance. No, you aren’t deer hunting at night, but target identification, in general, can get tricky if you aren’t careful.

If you’re looking for a pair of easy-to-operate thermal binos and you’d also like to be able to record video with them, the ATN BinoX 4T 4.5-18X Thermal Binocular might be the right set for you. ATN has improved quality and performance as time goes by, and these binos have proven to be reliable performers in the field.
