Most Helpful Positive Review Definitely worth checking out!
Is the Cronus ATS 50-640 thermal from Athlon Optics worth the price tag? When it comes to thermal optics for hunting, there are definitely a lot of options out there to choose from. I will try to keep this review shorter, but there is just so much to talk about, so bear with me here.. At first glance, the Cronus ATS has a really nice build quality. I am also definitely a fan of the more traditional scope look it has when compared to the bigger and blockier ones. The traditional scope style also makes navigating the thermal a lot easier. The weight of the thermal is comfortable to carry out to...

Restored my faith in thermals!

by Leslye, from UT, United States Written on February 28, 2025
Athlon gave me this free product to try and review. I had so little expectations about finding a solid thermal. I have product tested a few really prominent brands in the industry, and most had come up lacking. I surely would never choose to purchase the ones that I had tried: until this one! The Cronus ATS Pro 50-640 thermal scope is everything I had ever wanted in a thermal.
I started by taking it out several places along the mountain bench of the Wasatch in Utah, unmounted so that it did not startle anyone. I went to several canyons, a State Park known for wildlife, and several deep canyon sides. I used this scope in a variety of ranges from 200 yards up to the 3500 yard max and it truly did a fantastic job of detecting temperature changes. Granted that at extreme distance, I could not detect what animal I was seeing clearly, but I knew if it was a deer/elk/moose/bison versus a person or a warm rock.
Set up was a piece of cake once I settled on my 300 Black Out. This scope even comes with it's own custom rings for mounting. That made getting this scope secure and level a breeze.
The Wifi/bluetooth connectivity was super easy both at home and on the mountain. I loved sharing this scope test with friends and being able to watch along as they searched the mountain for animals. Using my phone to view allowed me to take still shots or even switch the camera on and record without disturbing the person behind the scope with me. At one point, we had a line of hike...

Thermal review 50 - 640

by Derek, from CO, United States Written on June 9, 2024
I have now purchased multiple of the new Athlon Thermal rifle scopes and all I can say is "WOW". They are high quality and exactly what I was looking for in thermals. I've owned multiple thermals over the years and I actually bought my 2nd Athlon thermal less than a month after the purchase of my first Athlon Thermal. That's how impressed with them I have been. Their abilities and functionality is 2nd to none and operate on the same level as thermal that cost 2x and even 3x as much as them. I can easily ID marmots, coyotes, mule deer, elk, moose, bears and many other animals that all reside near where I live in the mountains from very long distances for thermals. I highly recommend these scopes and wouldn't hesitate at all if you're in the market for a thermal. I am an extremely happy buyer with multiple Athlon scopes now.
Pros:
  • Quality, crispness, design, functionality, ease of use, aesthetics
Cons:
  • None

Exceeded Expectations!

by Dan, from FL, United States Written on June 6, 2024
This thermal scope exceeded my expectations! The clarity is amazing, and it's really easy to use. The 1440X1080 screen resolution makes a huge difference. The screen lock function on the zeroing is spot on! Highly recommended!

Fantastic Thermal!

by Eddy Wiebe, from KS, United States Written on June 5, 2024
Amazingly clear thermal, even on humid nights it cuts right through! For the price it can't be beat. Have compared it to several of my friend's Pulsars and it's easily as good. Way better than the XQ version and in my opinion it is clearer than the XP50 as well. Sold my ATN Thor 4 to get this and was blown away how much better I could pick up animals and identify them from much further out. Would highly recommend!!
Best Used for:
  • Predator and hog hunting
