Most Helpful Positive Review Geuinely surprised!
I was genuinely surprised with the Cronus ATS 50-640 thermal scope from Athlon Optics. It is a remarkable piece of equipment that delivers on all fronts – build quality, image clarity, detection range, ease of use, battery life, and versatility. It’s an excellent investment for serious hunters and anyone looking to get into thermal optics.

Extreme Quality

by Derek, from CO, United States Written on June 9, 2024
I've owned and used thermals for all sorts of hunting over the years and I am EXTREMELY impressed with the quality and functions of this thermal for the price point. I have zero complaints and I love the more traditional rifle scope setup look and feel compared to the bulk of the other thermals I've used. The ability to cycle through the different types of palettes with just a twist of a knob is so much more user friendly than other setups. I would highly recommend this scope to others. It works very well on both my AR style rifles and on my bolt guns.
Pros:
  • Functionality, price point, quality
Cons:
  • None

Excellent clarity, price, performance, and features. I can easily identify coyotes at a 600 yards. Can't say enough good things about this thermal. Might have to purchase another!

Really good battery life

by Donny, from LA, United States Written on June 6, 2024
Battery life is great! I went out for 5-6 hours with no issues. The scope includes 2 batteries, which is super convenient for long hunts. Very clear thermal compared to others in the same price class.

Enhanced by Smart Features!

by Jake K, from AR, United States Written on June 6, 2024
Paired with the Athlon Thermal app, this scope is even more powerful. The built-in wifi allows for live feed and recording capabilities. Better magnification, display resolution, and battery life than others in its class.

Cronus ATN 50-400

by Session H, from AR, United States Written on June 6, 2024
So impressed I just ordered another for another rifle platform. The FABs (features & benefits) are packed into this platform. Drove around with my brother in law and checked feeders and the hogs were everywhere. I could easily distinguish the hogs and cows about 600 yards out. This is the thermal for you if you are looking to jump into the thermal market alone, Expert Voice pricing made it easier to jump head first.
