Burris Thermal BTS35 V2 USM Review

First Thoughts on the Burris Thermal BTS35 V2 USM

The Burris Thermal BTS35 V2 USM thermal scope is a cutting-edge piece of technology designed for hunters, law enforcement, and outdoor enthusiasts who require advanced thermal imaging capabilities. Burris has packed this scope with features like 4x power zoom, hot track, stadiametric ranging, and multiple color palettes. It promises to be a game-changer for those operating in low-light or no-light conditions.

I was looking for a reliable thermal scope for nighttime hog hunts on my property, an issue that standard night vision struggles with due to heavy foliage. My goal was enhanced detection and identification capabilities, allowing ethical and effective harvesting.

The unboxing experience of the Burris Thermal BTS35 V2 USM was impressive, revealing a robust and well-constructed unit. The build quality felt solid, and the scope had a comfortable weight, suggesting durable materials.

Compared to similar thermal scopes I considered, such as the Pulsar Thermion XQ38 and the ATN Thor 4, the Burris stood out due to its intuitive user interface and the inclusion of the American Defense Mfg Quick-Detach Picatinny Mount. I wanted a QD mount for easy transitions between rifles.

My initial impression was excitement, tempered with a little skepticism about whether the real-world performance would match the advertised capabilities at the $2,499.99 price point. Only field testing would tell.

Real-World Testing: Putting Burris Thermal BTS35 V2 USM to the Test

First Use Experience

My first field test of the Burris Thermal BTS35 V2 USM took place on a moonless night in central Texas, during a hog hunt on my property. Conditions were cool and slightly damp, posing a challenge for traditional optics. The scope was mounted on my AR-15 platform rifle.

The Burris performed exceptionally well in these conditions, providing clear and detailed thermal images of the surrounding terrain and wildlife. The hot track feature immediately proved its worth by highlighting heat signatures of distant animals through brush.

The user interface was intuitive enough that I was able to quickly adjust settings without fumbling around. The rotary knob made navigating the menus much simpler than scopes that only use buttons.

The biggest surprise was the range at which I could detect heat signatures – well beyond what I had anticipated, making target identification much easier than with older thermal devices I’ve used.

Extended Use & Reliability

After several months of consistent use, the Burris Thermal BTS35 V2 USM has proven to be a reliable and durable optic. I’ve used it in temperatures ranging from freezing to over 90 degrees Fahrenheit without any noticeable performance degradation.

The scope shows minimal signs of wear and tear, even after being bumped around in the field. The IP67 waterproof rating has been tested and confirmed during a particularly heavy downpour, offering peace of mind in challenging conditions.

Cleaning and maintenance are straightforward. Lens cleaning and occasional wiping down of the housing are all that’s required.

Compared to previous thermal optics I’ve owned, the Burris offers superior image quality, extended battery life, and a more user-friendly interface. It has significantly enhanced my success rate during nighttime hunts.
