Thermal Wepon Sights

As technology rapidly expands into every aspect of our lives, one of the popular trends in shooting optics is thermal sights. These electronic sights see heat coming off of everything around us, particularly living things. This technology has made eradicating feral animals and dispatching pests not only easier, but a 24 hour activity. Today we are taking a look at another new to me thermal weapon sight. This one comes from Goyojo Optics, a company that makes a variety of sporting devices. Our subject today is the Goyojo GRL 335 Thermal Weapon Sight.

The Goyojo GRL 335

Goyojo’s GRL 335 is a compact thermal optic, that reminds me a little bit of the a Trijicon Acog. Despite its compact size and simple operation it is still packed with a great deal of features that make it very handy.

some of the included items are mounting brackets to change position of the mounting foot

Like most modern thermal optics, the GRL 335 incorporates various color palettes to select from. As well as picture in picture, photo and video recording capabilities. With its simple four-button control panel, you can zoom in, change colors and recording settings.

You can also access a variety of different menus to adjust things like reticle type and color. And change settings for the other features like shot activated recording. Zeroing can also be done within these menus. All images are captured on a 64GB micro SD card housed in the base, right next to the USB-C charging port. What appear to be turrets on either side are actually the battery housing. The battery itself can be removed and charged externally.

The ocular focus at the rear allows you to focus on the display. While up front, there is a blue ring around the objective you can use to focus the thermal sensor.

The whole unit comes neatly in a zippered soft case. Included with are a couple batteries, additional rubber eye-pieces, charging cables and a manual.

Mounting and Zero

Installing this optic on a rifle is very easy using the QD clamp. Much like other high quality optics, this one has its own clamping mount, with a security lock to prevent unintended opening. I clamped the optic to the sight rail of my rifle, and set it up looking downrange.

To zero the optic, I would shoot a shot, and watch the impact. Then you can freeze frame using the zeroing menu, with the frame frozen, you can move the reticle from where it is currently, to the point of impact. It took me a couple tries, but mainly that was me figuring out the system. But after a few minutes, I had it zeroed enough for testing.

I also took the time to familiarize myself with different reticle options, and different zoom settings. Once I was on top of it, I decided it was time to head into the mountains.

In the Field

Hunting is the true calling of thermal optics, and that is where I intended to use it. Early spring has some different hunting opportunities in my part of the country, but for now I would have to settle with hunting small varmints. Squirrels and marmots and if I was lucky a coyote would be my options. The AR15 rifle I had the GRL 335 mounted to was more than enough rifle for any of those targets.

thermal scopes and suppressed shooting are like peanut butter and jelly, here you can see my **Banish Speed K suppressor**

Over the course of several trips, I would use the Goyojo to find all kinds of animals. Both animals I could target as well as others that I wouldn’t.

Target ID

One thing I have found about identifying target animals with thermal optics, is that the environment matters quite a bit. Using the different color pallets in the GRL 335 was also helpful. Things like rocks and tree and other things can vary in temperature greatly depending on the conditions. Oftentimes it takes a while to get used to identifying things. Particularly in the day time until you see something that is actually living and warm it can be a bit challenging to know.

My dog probably wouldn’t like knowing it, but he shows up really nice in the scope. This is approximately 120 yards away

Again, using the different color pallets available is a great tool to help in this effort. The different zoom settings also are important to understand, for both scale and detail. And I also had to stay on top of the focus of the thermal sensor, keeping a sharp focus greatly helps you recognize both targets and their surroundings.

Controls

One of my favorite things about this optic is how easy and simple the controls are. Unlike some other thermal optics, the main and most important features are all within a single button push. Making quick changes in zoom, or snapping a photo or starting video can all be done without taking your eye off the display.

Of course many of the finer features can be changed by accessing the various menus. And the central placement of the button pad right on top makes it easy to acces. The textured pad also gives tactile identification, so even in the dark you can make adjustments on the fly.

Pictures and Videos

The ability to capture shots and videos through these optics is the icing on the cake. Not only do you get to have fun hunting, but you can capture the crucial events on film to share with others. I used the capture to get stills and clips of different hunting and shooting events. By pressing and holding the X button, you get a quick toggle between picture and video. You then capture a shot or start recording using the same button.

an image looking around the neighborhood in pure darkness (before mounting to the rifle of course)

All the images are captured on a micro SD card that is housed in the foot of the optic. The MP4 files can be transferred and used as you see fit. I did have a couple issues editing and manipulating the files, but I can’t tell you if that was a problem with the files or if it was simply me not using compatible software. Either way, as you can see I figured out a way to get both pictures and video where I needed it.

Focus

Adjusting the thermal sensor focus on this unit is very easy, its location makes it quick to grab with your fingers. And I like how it is recessed in the housing to prevent it getting moved inadvertently. Adjusting the sensor allows sharp focus as close as a few feet away, and i was impressed with how clean the image could be focused.

The display also has its own twist-to-focus feature. This is handy for those who’s eyes aren’t what they once were. There is also two different rubber eye cups to select from.

Useability

I’ve already mentioned how I like the simplicity of this unit. Particularly for someone who is new to thermals. It has some pretty concise instructions, and if you follow them you will have no problem running this unit.

Battery life is great, and the fact that it comes with a charger and extra battery means you can always keep a backup in your pocket.

Value

With an MSRP just under a thousand dollars, this optic is a great value. The ony thing left to ensure its value is its durability over time. This optic makes a lot of sense for a first time thermal, as it is more affordable than other options. I intend on giving this scope a good good thrashing to see how it stands up to use, make sure you check back in the future as I will update here as time passes.

Pros and Cons

Pros

Affordable- for the price its features and function are great
Compact- small footprint means less bulk
Quick to zero- easy to understand and adjust
Image Capture- both video and still images can be recorded
Added Accessories- mounting options, eyecups and other included accessories

Cons

Made Overseas- potential conflict
Unknown Brand-

My custom **Quattro 15 rifle**, you can read more about it here

Concluding Thoughts

I really like this optic, and I plan on using it to the extend possible in my hunting adventures. I like how simple it is, and how easy it is to adjust and understand all the features and functions. Whether you plan on using this optic simply for fun, or in preparation for an impending apocalypse, it gives you a simple sight that can be used around the clock.

GOYOJO GRS 225RF Thermal Riflescope with LRF

February 28, 2026Optics, Product reviewgoyojo, grs225rf, thermal, thermal optics, thermal scopecoldboremiracle

Preface

Our US Sporting Optics market has seen a flood of products over the last decade, to the point it would seem completely saturated. As I wandered through SHOT Show 2026 I was surprised with how many new optic suppliers there are, and they all seem to come from Asia. Today I bring you one of those options in the form of a thermal weapon sight. Our subject today is the GOYOJO GRS225RF Thermal Weapon Sight, a 1-8X digital zoom rifle scope with built-in laser rangefinder.

The GOYOJO GRS225RF Thermal

Perhaps it’s because I am old fashioned, but I often feel overwhelmed with thermal optics. There seems to be so many features, specs, and menus it can at times make me feel like the first WW2 vet to use an iphone. That being said, I do love thermal sights, and the covert ability they provide.

As I lifted the GRS scope from its box, I found out quite a bit just by looking at it. There is a large control pad on top of the occular eyepiece, from there you can perform rapid functions like power-up, start video or camera operations, and operate the laser rangefinder (LRF). Where you would normal find zeroing turrets, there are two knobs but not for what you’d expect. Where you’d expect a windage turret is actually a battery compartment to install a secondary CR123 lithium cell. The unit also has an internal battery that can be recharged. On top of the scope where an elevation turret would be, there is a free spinning knob that is used to navigate the menus inside the scope. This is done by turning the knob, and pressing down for select.

Included in the box was a few extras, like a battery, lens caps, and even a set of rings to mount the scope. Also included was an irritating amount of black fuzz, the box is lined with some kind of felt fuzz, and it covered everything inside the box. A quick blast of air got rid of it. Admittedly it took some time to figure out everything with this scope, as I said there is a lot going on here.

I also had to download the IR-Tracker V app for my phone, this allows you to view the scope display on your phone. As well as other options. Then it was time to mount the scope, in order to make it easy and inexpensive, I mounted the GRS to my custom 10/22. I figured the inexpensive and accurate shooting rifle would allow me to figure out the scope function and features on a budget before moving it to a larger rifle.

Zeroing Scope

With the scope mounted in the inexpensive rings, I set to zero the scope. This is usually done using a thermal or reflective type target. But I found it very easy to do by simply using the warm impacts of my previous shot to make an adjustment. The zeroing process is very intuitive, you can use the zeroing menu to freeze the screen right after a shot. Before freezing the screen, you put the reticle on your point of aim. Then you simply select the elevation or windage, and adjust the reticle from where it is, to where the last bullet impacted. In very short time, I had the scope zeroed and we were able to make very accurate shots within the range of the .22LR.

After which, I cycled through the menu using the top-knob. And selected a reticle and color that best fit my purposes. Additionally you can turn on a picture-in-picture (PIP) mode, so you can see a closer image of your center crosshair. You can even select where the PIP is located on the display.

Menus and Menus

There is a main menu as well as other sub-menus. All of them are accessed by the top turret, selecting them by pushing down on the turret. The back feature is always an option on each menu to move back to the previous menu. You can select everything from bluetooth and wifi options to connect to your phone, as well as functional options like the color palette shown on the display. Changing the refresh rate and other options for the thermal sensor can also be done this way.

There might be too much to go over when it comes to all the minutiae of sensory details, and technical data. More information if you are looking for specific information can be found on Goyojo’s website.

Heads Up Display

Using the different menus to select the features you want, changes the data displayed on the heads up display (HUD). The HUD gives you all kinds of external data like compass bearing, angle indication and the cant of your rifle. Date and time are handy for the photos and video recorded by the GRS and they are listed as well as available memory storage.

Information on the scope itself is also displayed. Both the internal battery and the extra battery power level are displayed so you can keep an eye on them. The zoom setting is also listed on the HUD, as is the aiming profile. Aiming profiles essentially being a setup for a particular firearm or barrel.

in this video you can see the shots impacting the target berm

Part of the HUD is your reticle, and you can select the reticle under the same menu as zeroing the scope. There are a variety of reticles to choose from, some very simple and others with various subtension points marked. You can also select a reticle color, which is probably better done after selecting a color palette. The differing color palettes show different terrain better or worse, some things show up better on one vs. another.

Video and Photo Features

With the ability to record videos and snapshots, the Goyojo GRS offers some great viewing. You can take snapshots using the main keypad, or record video. Additionally, the GRS has the option for recoil initiated recording. This ensures you get all your hits on video if that’s what you are after.

in this clip, you can see the Range Finder measuring 332 feet, followed by some changes in color palettes as well as a shot from a different rifle hitting the berm

Capturing images using the button is as simple as pressing it to grab a shot, or push and hold to start or stop a recording. When connected to your phone using the app, there are also photo and video controls that can be commanded from your phone. Some of the display features can also be changed from your phone, like digital zoom, color palettes, reticles etc.

When connected to the scope with your phone, you can download the videos and save them or airdrop them to a laptop. Pictures and videos both are accessed in the Document section of the IR-Tracker V application. I did have some troubles getting videos in a format I could edit and use them, but I expect that is more about me not understanding technology than anything.

On the Range

With the rifle zeroed, we set to shooting with the GRS thermal scope. Picking out targets can be a little more challenging with this scope. Depending on ambient temps and conditions like sunshine can make things hard to identify. I often compare thermal images to ultrasound images. When looking at a thermal image you have to understand what you are seeing and what you aren’t, like a photo negative image. Once you understand this, you can better understand what you are seeing.

Obviously if you are looking at a warm animal moving on the display, it is much easier to identify. But picking out things like a box, or rock that mimics the ambient temperature is a little more challenging at times. But once you do get a good understanding, and can see and identify what you are shooting at it becomes much clearer.

goyojo optics, goyojo GRS225RF, thermal, thermal scope, lrf, laser range finder, screen shot, reticle, — Screenshot

Shooting at small rocks in distant dirt was easy, because the rock was warmed by the sun while the soil was cold and wet from the melting snow. Seeing bullet splash in the cold soil was easy to identify misses, while seeing a white flash on the rock would show you clear hits. After a great deal of practice like this, we swapped the scope to another rifle to repeat the process.

Centerfire Use

I decided to mount the GRS225 thermal scope to my Desert Tech MDRX, which I’d configured to a 20-inch .223. This would be perfect for pursuing coyotes, raccoons or any other pest that needed eradication.

I again followed the zeroing procedure, getting a solid zero at one-hundred yards. And practiced shooting at a variety of distances holding over using the reticle.

Pros and Cons

I expect that many of my issues figuring this scope out are more about me than anything. I’ve had the same experience with other thermal scopes as well. One of the main positive things about this optic is its price. Similar optics in the thermal department at Optics Planet go for three to four-hundred dollars more if not three to four-thousand more. Of course, as we have come to know in life, the cheapest option isn’t always the best one. And when you consider this scope comes from a relatively unknown manufacturer (at least in America), that might make it a bit of a concern as well. For some people, the 中国制造 alone is reason enough to avoid it. Preferring something manufactured domestically, which I can totally understand.

Value Proposition

Considering that the thermal scope market is quickly becoming littered with options, this scope has many competitors. As I mentioned earlier though, many of those competitors cost significantly more than this one for similar if not the same basic features. For the MSRP of $760 this seems like a very affordable option. Though I must say the sensitive nature of electro-optics, especially those that run on software can be a little scary. By that I mean; even if this scope costs half the price of others, $760 is a lot of money to lose if the scope simply shuts off for good. Therefore the durability of products like this one are very important. It has worked great for me so far, but time will tell if its is worth the price. Check back here in the future as I will update this as the product ages and is used.

Concluding Thoughts

It can be challenging and a little intimidating to get into some of these new tech items. But we’ll all have to do it at some point. I have been impressed with all the bells and whistles of this scope, and provided its quality hold up, I expect to use it for many years to come. Chasing varmints and predators in the darkness where they hide.

The Goyojo GRS 225 thermal scope is an affordable option with great features that hunters are going to enjoy. I will continue to update this article as my relationship and use of it develops.

Andres Industries TigIR-6Z+™ Thermal Sight

March 24, 2023Optics, Product reviewandres industries, thermal, thermal optic, TigIR, TigIR-6Zcoldboremiracle

I am lucky to often play with military grade weaponry, but today we will be talking about military grade optics, thermal optics to be exact. Today we will be looking at the Andres Industries TigIR-6Z+™ Thermal Sight. The TigIR is a compact clip-on thermal sight meant to be used in front of your day optic.

The TigIR-Z

I tested the TigIR on one of my SRS M2 rifles chambered in 338LM, on top of the rifle was a Steiner M5 riflescope.

The TigIR has some very convenient features that make it rapidly deployed and easily adapted to your application. Things like a quick power-up when opening the front lens cover, assorted mounting options, and offset adjustment to remove optical offset. I really enjoy some of the nerdy tech side of shooting, so let’s get tucked into this review.

Target hangers as seen from 200 Mts at zero fahrenheit

The TigIR comes in a very nice little polymer carry case with a detailed instruction booklet. Written in both German and English, which came in very handy since my German is a bit rough. One of the first things that surprised me about it was for an optic so filled with functions and features, it only had four buttons. There is a fairly complex menu that is navigated using only the four buttons. Using either quick presses or holding the button depressed until selected. But first I had to install the four CR123 lithium batteries.

Settings

The TigIR has several filter options that allow different views of different landscapes, each one having a strong-point. The different filters are easily toggled through to see which one best presents your target in any given place. There are also several different brightness settings you can use to adjust to your purposes. The waterproof housing also has a connection for video output and remote control.
In addition, the TigIR allows you to create several profile offsets within the device for different rifles or calibers. When you add a thermal sight to your rifle, or anything to your rifle for that matter. It can affect the way the rifle recoils and change your point of impact. In addition, when you put an additional device in front of your day scope that is zeroed to the rifle. You can also cause an optical offset (sorta like a shallow prizm). The TigIR allows you to correct for this offset. So that your point of impact remains the same with or without the thermal installed. And as I mentioned you can save up to six different profiles to use with the TigIR.

Brownells has a great selection of thermal devices to shop

The front lens cover is held shut by two bungees, the unit powers-up when you open the cover. The bungees then hold the cover firmly in place to avoid unwanted movement. It can also be used for rapid recalibration, by simply closing and opening again it will cause the unit to reset. After startup you can select a power setting from .8X up to 6X, this is handy for various viewing purposes and are easily toggled with the zoom button (#2).
You can select one of the fifteen or so different filters. Each of them have strong points such as looking for a person vs. looking at a vehicle. Some of the filters are much better than others depending on what you are looking at. So make sure you try several different options.

Euro Optic sells an excellent selection of thermal optics

The TigIR is easily mounted using a clip-on picatinny rail clamp. There are other options such as scope-bell clamps as well as observation eyepieces to use the unit alone. The four batteries should power the unit for ten hours according to the manufacturer. Though in my experience I would not expect it to last near that long in this kind of cold.

Shop different Mounting accessories here and here.

I must admit that the lionshare of my time was spent learning how to operate the TigIR. Which is no surprise as it is a complicated device. It took some trial and error for my captain caveman brain to get everything figured out. But after some time I was ready to make some noise.

To the rifle range

The TigIR mounted to my **Desert Tech SRS M2**

Having already ensured my rifle was zeroed at one-hundred meters. I clamped the TigIR into place to see what happened next. It’s not often that I play with thermals, and I always forget to bring something warm to use as a target. But to my surprise I didn’t really need one this time, targets and details show so clearly through the TigIR that it was almost unnecessary. I could even see the differing colors of the paper target, as long as the sun was shining on them. As temperatures changed so did my perspective of the targets. It was actually easier to shoot into the snow. The fresh holes in the snow would show up quite clearly through the thermal. After confirming the offset, I entered the offset data into the profile for my 338. This would ensure that with or without the TigIR installed I would be on target.

Observing target handlers, note “WH” denotes selected IR filter, and 0.8X denotes selected zoom

Thermal Imaging through the TigIR

The images portrayed through the TigIR were quite impressive, making an incredible amount of detail possible. I pushed it out a little further to see how well I could see things at six-hundred meters, and it was still very useful. I continued to shoot and to my surprise I could even see sticks moving behind the target as they were hit by the bullet after passing through.

It was actually quite impressive until thick fluffy snow began to fall. As the air filled with frozen snowflakes the magnified image became unclear with or without the thermal installed on the rifle. I did try some of the other thermal filters and did get some improvement. Though not enough to make it worth spending expensive 338 Lapua rounds. I’ll also add that the images shown here don’t show the quality as well as your eye does in real time.

Shop various thermal optics at Mile High Shooting

You can also select one of several reticles from the TigIR menu. Different reticles with differing values that can be used either independently of you day scope, or in conjunction with it. And if using the TigIR as spotting device, you can use the reticle values to call corrections for your shooter.

Conclusion

I was thoroughly impressed with the TigIR-6Z. It was very compact compared to other units, and it performance was better than those I am more familiar with. Yes it is a complex piece of tech so there is definitely a learning curve. But I think once you figure out how to use it properly, you will be very happy with it. The price is just shy of €10K, which is certainly not cheap. But it much more affordable than comparable units I have used. I would definitely get one of these units if you’re in the market for a thermal. Its an outstanding little device.

ATN THOR 4 640 2.2-25X thermal riflescope

December 28, 2022Optics, Product reviewatn, flir, night vision, thermal, thermal scope, thor 4coldboremiracle

Thermal Optics

Being in control, or at least feeling like you’re in control of a situation seems to give us satisfaction in our outdoor adventures. Being prepared with weapons and the tools needed to go where we want, and do what we chose are a large portion of that feeling of authority over our immediate surroundings. Until the sun sets, when much of our dominance goes out the window. Today we are going to take a look at some equipment you can add to your arsenal that will keep you on top of things in pure darkness. ATN Corp has been in the business of manufacturing low light sport optics for nearly 30 years now. They have been innovating night vision and thermal devices in every imaginable way. Today we are going to speak about one product in particular, ATN’s THOR 4 640 2.2-25X thermal riflescope.

The THOR

The ATN THOR 4 is much more than just a low light thermal imaging optical sight. It also has an incredible array of smart functions like built in GPS, blue-tooth connection to apple and android devices, video and photo recording, and even ballistic solver built into the riflescope.
There are other more simple features that will enhance your experience with this scope as well. Rings to mount it come included with the scope, low battery consumption make the power last longer than anticipated. And you can even get it in one of your favorite camouflage coatings. There is much more to get into on the features, so I’ll move along.

Unboxing

When I opened the box to see the scope inside, I was a bit surprised. The THOR appeared to be a complete unit, sealed and ready to go. I pulled out the instructions because I’m an idiot when it comes to tech. The directions were easy enough to figure out, but for added help for those of us who struggle they even added some stickers in various locations indicating the purpose and function of each control.

Control panel on top of the housing, note charging port and SD card slot

There was also things such as a charging adaptor and the mounting rings to install the scope on your rifle. After a few hours good charging time, I took the THOR outside to see what I was missing in the darkness. I have used other thermal optics before, and I was perhaps expecting a little bit more because of my previous experience. But to be fair, the units I was comparing to this ATN cost three to four times as much. So there is certainly a grain of salt to take with my expectation.

The THOR was excellent for identifying small animals around the neighborhood inside 300 yards. I zoomed the power in and out using the power wheel on the left side of the housing, and then focused using the rotating objective housing. The resolution was more than adequate for identifying and targeting potential animals.

In the field

I wanted to get this scope mounted and into action as soon as possible. Using the provided rings, I mounted it up on my Desert Tech MDRX 308 winchester.
It took some getting used to, but after a bit I had the THOR figured out. I managed to get it zeroed, though it took me more shots than it should have. The “Nuc” feature was an important one to figure out quickly. As far as I can tell, it seems to calibrate the sensor according to the current field of view. I found that significantly changing your field of view would cause some of the resolution to vary some, and by cycling the Nuc feature on the new viewing area would bring back the image. There is also an “Auto-Nuc” that you can set in the controls to have the device re-Nuc itself every so often.
The display was full of information, possibly more than some folks may want to see. It kinda made me feel like I was looking through the heads up display of an F-18. Angles on both vertical and horizontal plans are displayed, as well as a compass heading. There are an assortment of reticle choices you can choose depending on your needs, as well as a simple menu that can be cycled through quickly using the buttons on top of the housing. I had already installed a micro SD card that is used to store images and video clips recorded through the scope.

It was time to get the Obsidian 4 application connected and running, this app is made and offered by ATN for the owners of their products. It allows details entry and customization for some of the more tedious bits of data you definitely want right.
It took a minute to figure out how to properly get it connected to my phone, but after watching a helpful video on ATN’s website I was in business.

The Obsidian 4 app allows you to customize the data used in the ballistic solver that comes in the scope. You can change calibers, bullet weights, velocities and other pertinent information used to calculate the corrections for distance. You can also watch through the scope remotely which is also pretty cool, there is a slight delay in transmission but you can see everything you need to see and record it to your phone if you like.

The app was easy to navigate, and update the information. To be completely honest I found it to be an incredible amount of customization, I am barely smarter than most primates and I was beginning to worry I was going to screw something up faster than anything. But in a short time I had it setup to my liking, and ready to shoot. Continue Reading Here…

THE THERMAL DIFFERENCE

As far as thermals go, I was quite pleased with this one. I could see myself using it quite a bit more now that I am familiar with its functions and features, which are far more than I had anticipated.
Battery life was impressive, even in the ice-cold Rocky Mountains. I could leave the Thor powered up for hours at a time for most of the day’s shooting activities. With a full charge after leaving it in the cold garage for two weeks, it still powered right up to about 90%. The actual optical controls (focus, zoom, etc.) were a little more sensitive than I’d have liked, but I guess I can live with it given the thermal advantage the scope offers.

I didn’t use the ballistic calculator much, but I don’t really use them much inside of 300 yards anyway. The pictures and video taken from the Thor were fantastic and easy to get and upload where I wanted them.

CONCLUSION

Thermal and night vision products are not for the faint of heart. Companies like ATN are doing their best to bring the price down and present options to the general consumer. Nonetheless, it will take a level of dedication and funds outside the normal gun enthusiast. Think of it like NFA items. The added cost and a little more diligence are needed, but the results are too cool to not have. I certainly don’t mean to put you off getting into thermal sight like the Thor, just want to make sure you know what you’re getting into.

My only concern with this scope is about longevity, it does come with a 3-year warranty, which certainly assuages some of that concern. I do look forward to spending some more time with this scope and hopefully getting some good video of coyote hunting.

ATN BinoX 4T 2.5-25X thermal binoculars

Thermal Weapon Sights

Thermal weapon sights have become extremely popular over the last decade or so, I’ve had the good fortune to play with a few of them. Today we are going to talk about a supplemental thermal device, one I think is just as useful as a weapon sight; the ATN BinoX 4T 2.5-25X thermal binoculars.
I say just as useful because whenever I find myself in the dark looking for potential animals to hunt, looking around through my riflescope is not only cumbersome but dangerous. The BinoX binoculars allow the user to safely scan the surrounding environment to identify potential targets, and it also gives you additional information that will help you make a better shot when the time comes.
The ATN Binox incorporate a rangefinder, variable power settings, video recording and image capture, and even GPS location that can be used to keep track of fellow hunters in the area. An IR illuminator is also part of the device, which allows you to illuminate targets when using in conjunction with night vision optics. It also incorporates wifi that can be paired to your ATN riflescope through the ATN Ballistic Information Exchange (BIX). Using the connection you can also stream to a paired device for additional viewing while recording the stream to the SD card inside the unit.
The ATN Binox uses an armored housing with a control pad on the top with various buttons to cycle through the menus and activate the different functions of the binoculars. At the rear of the binos you have an adjustable diopter to focus the image of the display inside. The front of the sensor lens can be rotated to focus the thermal image of the target, the right side is for the thermal sensor, the left side houses other sensors and needn’t be adjusted for image focusing.
The Center button doubles as a “Nuc” button that resets the sensitivity of the sensor based on the current field of view, as far as I can tell anyway. You can adjust the power magnification of the binoculars by using the arrows on the control pad, and the power button doubles as a rangefinder trigger when the unit is powered on.
The display inside gives you quite a bit of information, with actual readouts of both incline and cant as well as a compass bearing. You can select to use different widgets such as compass and angle displays, or if you like you can keep it simple and see just the image. There are many different settings that you can adjust to better fit your needs such as different shades for showing heat, you can select different colors or shades of black and white. There are different reticles you can use for measuring targets and distances and such, and of course you can change the units from yards to meters and MOA to MRAD if you like.

The Binox come with an extended life battery, which I was happy to hear. Most thermal devices I have used in the past burn through batteries far too fast. There was also a neck band to carry the BinoX with, it was also easy to adjust the two ocular lenses to fit your particular eye width.

Into the darkness

After confirming a bunch of settings around the yard and making my dog uncomfortable with shouting commands into the dark corners of the yard, I decided it was time to take the BinoX into the hills and see what I could find. It took a few minutes to find a contrast setting that I preferred, but I settled on the “Glowbow” setting. As you’ll see from my pictures I neglected to set the time and date.

Once I got into the mountains I began scanning where I figured I would be able to find a deer or two, or perhaps even a unsuspecting hiker. I did find something that quickly became frustrating. There were plenty of rocks in the hills that appeared to retain a bunch of heat, this inevitably gave me too many false ID’s of potential life. When I actually did see something that was clearly alive and warm, it was pretty clear. But often times I would have to watch at some of the more distant targets to see if they moved before I could confirm their identity.
I spent some time getting used to the imagery through the binos, and testing out the different functions. It did take me a minute to get used to some of the controls and understand everything, but soon enough I was finding things and measuring their distance with the rangefinder and even snapping pictures and videos of them. Much like properly viewing an ultrasound image, it seems there is a bit of a learning curve with looking at images like this. Oftentimes it is easy enough to make out trees, rocks and so forth. You can even make out sunny spots and shadows in the images taken during daylight. I have seen better imagery from other thermal units, but to be fair they cost significantly more than this one.
Finding animals in complete darkness turned out be be everything I hoped it would be, it reduced the eeriness of the darkness. Thermal optics have the benefit of being useful in the daylight just as complete darkness, which is a leg up over night vision optics. I found that using the BinoX during the daytime was also helpful in finding things that were alive in a sea of ambient temperature trees and hills. Continue Reading Here…

SOME DRAWBACKS

I’ll go over the negative things first, as I’ve mentioned I have used other high-dollar units so take my opinion with a grain of salt. One of the most significant things I didn’t like with the BinoX was that things that weren’t warm showed up as if they were. This is likely technological ignorance on my part, it appears that the sensor shows differences in temperature more than anything. For example, the deer I was looking at are surely warmer than anything else on a sub-freezing mountainside with scattered snow at 6:00 AM, but even so many of the rocks on that hillside looked as if they were warm in the BinoX.

The rocks were a whole other color/shade than the ground and trees but were clearly discernible as well. I guess I was just hoping that only warm things would show up as such on the display, but to be fair I got used to it fairly quick, and it ceased to be as difficult.

The rangefinder works, and I tested its accuracy alongside another comparably priced unit. I like rangefinders that reach the two kilometers or more, but for use in the darkness it’s probably better to stay fairly close. Ranging targets inside 1,000 yards seemed to be easy with the Binox, but I didn’t care for the large opening in the ranging reticle, I think it could use a more precise aiming point.

I am not sure what the laser divergence is for the rangefinder, but perhaps the reticle size is based on the beam divergence.

I was unfortunately unable to try the Obsidian APP that I downloaded to view images from the BinoX, I wasn’t able to pair the device and the live chat support on ATN’s website was unable to help me as I wandered around in the darkness.

WHAT I LOVE ABOUT THE BINOX

Now for the good news. I was very excited to be able to see so many things in the dark that were previously unknown. These Binoculars are an awesome tool if you are trying to locate animals in the darkness, or very low light. I suppose you could even use them in the daylight to locate animals. The zoom function is pretty easy and quick to increase your ability to identify targets, and I was pleasantly surprised that resolution wasn’t lost as I zoomed them in.

I was certainly impressed by the battery life, particularly in the cold sub-freezing temperatures in the high Rocky Mountains. The unit has a standby/sleep mode to help conserve the battery, but I wanted to see how long it would last without it. On multiple occasions I would fire the unit up an hour or so before daylight, and I would use it until the deer would begin to bed down around 10-11 at night and the battery was still chuggin’ along!

The photo/video feature is very handy, it was as simple as tapping the button to get saved images of the animals I was watching. Almost too easy in fact, as on several occasions I found I had bumped the video record button and had filled my card up with videos of my feet.

The image quality was as good as I had expected it to be and it gave me an incredible feeling of dominion over the darkness before me.

CONCLUSION

Thermal imaging is definitely not for the penny pinchers out there, there are a variety of BinoX models available but the most affordable chimes in with an MSRP of $2,699. Needless to say, it can be a hard pill to swallow for most. Though you might find it extremely fun to prowl the darkness, you won’t be able to occult such a purchase from your spouse without risking your own body heat. But if you have the ability to buy products like this, then you will surely enjoy them as I have.

The ATN 640 4T BinoX will take your hunting to a whole new level, and the features make it a pleasure to use. Watch for my next article about the ATN THOR 4T HD Riflescope.
