Over the years, I’ve come across many thermal scopes in my line of work. I was specifically looking for one suitable for long ranges with a decent reticle for my early morning hunts. That’s how I ended up with the ATN Thor 4 thermal scope, and it has been a game-changer for me. In this ATN Thor 4 scope review, I’ll share my experiences and thoughts on this scope.

Specifications and Background of the ATN Thor 4 scope

American Technologies Network (ATN) Corporation is a renowned tech optics company that was founded in 1995. They are a market-leading manufacturer and developer of high-resolution smart optics for day and night operations and smart thermal imaging optics for night operations. They have a good brand reputation because of their commitment to the quality and functionality of their products and that’s one of the reasons why I tried the ATN Thor 4.

Before diving into my personal experience, let’s briefly cover the specifications of the ATN Thor 4.

The ATN Thor 4 scope comes in two colors, Matte Black and Mossy Oak Elements Terra. With a 1.25x-5x magnification, it gives a broad field of view of 16×12.5 degrees to better spot targets in the field. It has a 750-yard detection range, 335-yard recognition range, and 205-yard identification range which allows to identify targets at different distances. ATN loads this thermal scope with advanced features. It has a mil-dot reticle for precise aiming, while the ballistic calculator assists in making accurate shots by considering factors like distance, wind, and bullet ballistics. The scope has a night vision for low-light situations, and the obsidian core makes images clearer for a better viewing experience. The ATN Thor 4 runs on an internal lithium-ion battery, lasting up to 16 hours. This means you can use it for a long time in the field without worrying about running out of power.

ATN Thor 4 Features

1 Button Control

2 Scroll Wheel

The scroll wheel allows you to adjust the magnification and get dialed in.

3 Diopter Adjustment Ring

Rotating the diopter adjustment ring lets you get a sharp, crisp image.

Review of the ATN Thor 4 scope

I’ve got my hands on some of the other ATN thermal scopes, but the design of ATN Thor 4 was sleek. It comes in two color options and I got mine in matte black and the finish of it was smooth.

Setting up ATN Thor 4 on my crossbow was pretty straightforward. If you need any help setting up this scope, it comes with a user guide that details all the steps you need to follow, so I recommend reading it.

I have been using this scope for over 3 months now and it has been consistently delivering results. I chose the 1.25x-5x magnification for my thermal scope. It was perfect for spotting my targets in the woods and zooming in when needed. I got sharp visuals up close and scanned wide areas quickly during my first hunt. My only regret was not picking a larger base magnification as I’ve heard it performs better for  shots beyond 200 yards. 

Using this scope’s thermal imaging optics and human detection range, I took down hogs that were over 150 yards away easily. The shots were accurate and zeroed in perfectly. Speaking of durability, it handled the outdoors quite well. I didn’t face any mechanical failures, but it had little cosmetic wear. 

The ATN Thor 4 scope contains features such as a smart mil-dot reticle, ballistic calculator, and fusion thermal imaging. The ballistic calculator came in handy when calculating the wind deflection and fusion thermal imaging improved the visibility of my targets in low-light situations. I was overall satisfied with the reticle performance of this scope.

There are also some cool features on the ANT Thor 4, like a built-in GPS transmitter. This sends the precise impact location to your phone or GPS device. However, I am not the biggest fan of tech gimmicks on my scopes. But one feature I liked is how I could use this thermal optic scope to film my hunts and easily transfer them to any Bluetooth device. I personally don’t record my hunts, but I see myself doing it in the future with this scope.

ATN thermal scopes are well known for their long battery life and ANT Thor was no different. It never died on me. But if you’re someone who hunts long hours at night, you can get the ATN extended power kit that can last up to 22 continuous hours.

There was one issue that I faced with the ATN Thor 4. The device would freeze and it required a hard reset to get it up and running.

I think the ATN Thor 4 is a reliable choice for enthusiasts who hunt at night and are interested in features like night vision and thermal imaging. With that being said, I still prefer normal scopes for my general hunting sessions. 

ATN Thor 4 Pros and Cons 

  • Thermal is like a super power!
  • Good thermal detection range
  • Video recording
  • Built in GPS
  • Pricey

Report Card


We did not experience any reliability issues, but if you do go for longer hunting trips you may want to get the power kit.


The imaging is great and you can easily tell what you are looking at.


There is a lot of information on the screen of this optic, but it does not interfere with your aiming or overwhelm the user.


This is a bigger and heavier than a standard scope, that may be more tiring in the field to carry around or aim.


Thermal sights are cool, but often not in a realistic price point for most crossbow hunters.
