Great scope.I bought this scope in July 2020; I opened box charged the battery and looked through the scope.It came on, made things brighter, seemed ok. During this time, I was working a lot of overtime, like 20-30 hours a week which didn't leave much time for anything else. It worked out that I got an early retirement, because at the time I was doing a major rebuild on my home. Five years later I had time to check out the scope. I charged it and it made everything brighter, but no reticle no info on screen, like it is on YouTube. I contacted ATN Tech support and spoke with Oliver. Nice guy talked me through everything, and decided they needed the scope back for evaluation, they sent me shipping label at no cost to me. I knew I would owe stupid tax for not checking it out better when I received it 5 years earlier. Well, to my surprise I received a brand-new scope. ATN paid for everything for FREE. The customer service was exceptional. This is the only interaction I've ever had with ATN. I was blown away. I can only sing their praises. This is above and beyond and beyond. Oliver from customer service was amazing! Thanks for your help with this.

Absolutely fantastic!This is my fourth ATN scope. I started with a first-generation X-Sight and then moved on to two 4k X-Sights. I’ve been using this scope for a few months now, and it’s incredible—worth every penny. The optics are crystal clear, and the reticles are easy to use, providing clear visibility during the day and night. The accuracy is dead on.The integration of the range finder and scope makes this a formidable tool. Simply measure the distance by pressing a key, and ensure that ballistic calculations are active. Done!I’m particularly impressed with the battery life of this scope. The first-generation models required external power, but this one doesn’t show any battery usage after an entire night in the blind. The build quality is solid, and it looks fantastic on my precision rifle. With this setup, I can confidently shoot feral hogs in the head at 200 yards, even in the dark. The picture is incredibly clear and defined, which is why I prefer this setup for static hunting (like from a blind) over a thermal scope on an AR.

Works just like they say, very happy with this product. No Issues so far and from my research sound like ATN stands behind their product.

We received a faulty scope. Very hard to get tech help from ATN

The scope does exactly as advertised except it is a bit grainy when zoomed right in.There is a problem with accessories working great then just stop working and a nightmare to get working again. It’s a common problem with accessories being hit and miss (remote and abl)

Worked great till temps fell below -30 Celsius. But then I wasn't functioning well either. Good bang for the buck.

Pretty awesome scope !!! Night time is crystal clear !

PREFACE - Before buying I literally read every single review on Amazon and read countless others on other websites, along with numerous videos. So below I will also address some of the previous concerns I’d read about from other reviewers (Spoiler Alert – ATN has obviously fixed or corrected everything thing that I’d read about). ;-)NIGHT VISION - Is Amazing!!!Basically, the night vision I’m seeing certainly seems to be VERY comparable to other “Night Vision” Scopes that cost MUCH more ($2K to $3K). So I am VERY impressed so far. Also unlike “regular optical night vision” (which is green) this system (which looks gray scale) does NOT get damaged if left out in the sun, nor does it have to be protected from light. Plus, the same scope is used during the day (double bonus). And, even when the infra-red illuminator is OFF…I was actually surprised…it was still MUCH better than I thought it would be (it does NOT need much light to be effective). So then, when the infra-red Illuminator is turned ON (even at its lowest power)….it really lights up everything like it is daylight when it is pitch dark. I am SUPER impressed.

It’s so good, I’m going to mount it to Quick Disconnect Rings, so I can use it as a Night Vision Monocular (even when not attached to a firearm or airgun.MULTIPLE ‘PROFILES’ -What a game changer…something only a digital scape can do. Essentially, a person can enter different Profiles for different firearms or Airguns and/or ammo…and with a Quick Disconnect (sold separately) it with be a cinch to switch.MICRO SD (sold separately, I got a SanDisk Ultra Plus 64GB)It is important to READ all instructions (which I did), where my friend did not. He and few reviews said they had Micro SD problems…well it’s important to do the Formatting in the Scope (it likes that). Plus, it will also be nice, as a person can "backup" their profiles to the Micro SD card, too.FIRMWARE UPDATES -Again, it’s important to READ all instructions…every single thing I’d read about or saw as an early model 2018 “glitch” has obviously been addressed with Firmware Updates. There was a Firmware Update for mine…and right away I got a super cool “Smart Reticle” that I did not have 1 minute earlier. So follow the instructions. And that “Smart Reticle” changes as you Zoom…again, things that only a digital scope can do.TWO (2) LIL’ ISSUES - That Oliver Vallero at ATN Corp Clarified and Fixed for Me…The USB A to USB-C charging cable that came was way too big to fit in the Scope’s USB-C slot. My buddy that also bought one, a day after I told him about mine…his also came with a USB-C that was too big. He and I are both Apple Techs, so we know it was not a matter of being tight…it was too big. Yet, being and Apple Level III Tech we both had other USB-C cords I/we could use until Oliver sends out a new cable. Plus, I supposed I could have cut away on the plastic on the USB-C end, but I’ll wait and see. 2nd thing…Oliver mentioned that the Manual’s suggested torque of 38 in.-lbs. was too MUCH for the Fixing Screw. So for everyone out there use 22-25 in.-lbs. / 2.485-2.824 Nm for the 30mm Scope Fixing Screw…and for the 30mm Scope Ring Screws, use 15 in.-lbs. / 1.694 Nm. Then finally, for the Infra-Red Illuminator use 22-25 in.-lbs. / 2.485-2.824 Nm for the Fixing Screw, and the Infra-red Illuminator Ring Screws use 12 in.-lbs. / 1.355 Nm.PHOTOS & VIDEOS -I’m really not planning on using it for photo’s or recording video to the SD card (but broadcasting to an iPad might be interesting with shooting buddies).WI-FI & ATN OBSIDIAN 4 App (Tips & Tricks) -The Obsidian 4 App is great for me and works GREAT with the iPhone 11 Pro. I’ve got it set up with a mount that holds my iPhone 11 Pro around my neck and puts the screen where I can see it like a heads up display w/no-hands…so for hunting rats at night…I just put the Umarex Synergis w/ATN X-Sight 4K Pro on a Tripod w/a Vanguard U-Yoke ($14.99 w/Free shipping) and I do NOT even have to look through the scope…I can just watch my iPhone and when the rats come out…POP. This is sooooooo cool!
Well, that was long and detailed, but that’s me…hope it helps others! :-)
