About the ATN ThOR LTV

ATN offers a number of ThOR thermals, 12 in the LTV series with resolutions ranging from 160×120 to 640×480 .

The ThOR LTV lite thermal 320×240 (12 μm) series has three different magnification ranges: 3-9x, 4-12x, and 5-15x. We have the 4-12x model. 

From ATN:

This scope does not have Wi-Fi or the companion app connectivity that other products have, so I set it up on our optics test rig for easy demonstration. 

It does, however, have video recording, one-shot zero, and a number of reticle options and features.

There are a number of color modes in both black hot and white hot. 

Black and White with Black Hot

What’s in the Box

This scope comes wrapped in a zippered neoprene sleeve with a telescoping hood assembly, USB-C power cord, and owner’s manual. This sleeve also has an interior pouch for convenient cord storage. 

About the Rifle and Installation

I put my 6mm ARC barreled action into an APW Carbon X stock and removed the weights. I had the ATN X-Sight 5 set in Athlon rings and used Wheeler’s professional gunsmithing set to do a scope swap.

I still had to level the ThOR LTV, but I didn’t have to adjust the bottom rings. I used the Wheeler precision level kit for this task.

I then zeroed the rifle at 50 yards using a hand warmer, only to realize the low rings didn’t provide enough bolt clearance. I subsequently switched them.

I had to swap rings due to bolt interference.


Hand warmers stapled to cardboard make quick and bloodless thermal targets. I zeroed again at 50, used the one-shot zero feature, then moved to 100 yards and got my next zero.

I then progressed to the ridgeline barricade to engage rockchuck targets I’d heated with a propane torch.

My dog Dennis helped with night testing once again, serving as a 100-yard model while I looked through the scope. (The rifle was empty with no ammunition during this test.)

I did all of my shooting with the 6GT before moving the scope and stock completely over to my new 22 ARC build.


I really liked most of the color modes from this thermal and it works well as a reasonably-priced thermal. If you move up to a higher-priced model in the ATN line, you’ll have better clarity, but the ThOR LTV still allows you to discern animals. Looking forward to seeing how it works on coyotes!
