Burris USM C35 V3 Thermal Clip-On Scope (Model 300623)

The Burris USM C35 V3 thermal clip-on scope is a modern take on thermal hunting optics—designed to mount ahead of your existing day scope and deliver real-time thermal imaging without replacing your primary glass. Built around Burris's Cybercore technology, this thermal clip-on brings a 400x300 resolution sensor and a 35mm F1.0 lens to the field, giving you a 7.8° × 5.9° field of view that balances situational awareness with detail. The 12-micron pixel pitch sensor delivers crisp, high-contrast thermal images even in complete darkness, making it a serious option for night hunting when conditions demand thermal detection.

What sets the C35 V3 apart is its user-centered design philosophy. The rotary dial control system operates intuitively in total darkness—no fumbling with buried menus or tactile guesswork. A 400x300 VOX sensor with 50Hz refresh rate keeps your image responsive and smooth. The clip-on format means you keep your daytime hunting workflow intact and add thermal capability on demand, a practical middle ground between full thermal scopes and standalone thermal monoculars.

Connectivity and convenience matter in the field. The BurrisConnect app streams real-time video and captures stills directly from the unit, plus remote control of key settings. Two 16340 rechargeable batteries power the optic with roughly 2 hours of runtime at 25°C, and selectable auto-shutoff (5, 30, or 60 minutes) stretches field endurance. Hot-swappable batteries let you rotate fresh cells without powering down, and USB-C charging is built in. Image options include five color palettes—White Hot, Black Hot, Red Hot, Green Hot, and Blue Hot—so you can optimize contrast for your specific hunting environment and personal preference.

Whether you're chasing coyotes, hogs, or varmints under starlight, or scouting predator sign after sunset, the Burris USM C35 V3 merges proven thermal performance with modern app integration and field-friendly ergonomics. It's night hunting technology that respects your existing gear and your ability to operate gear in the dark.

Frequently Asked Questions

Will the Burris USM C35 V3 thermal clip-on work with my existing rifle scope?

Yes. The C35 V3 is designed as a clip-on thermal optic that mounts ahead of your day scope, so you can keep your primary glass in place and add thermal capability without replacing your setup. This makes it a flexible option if you already have a trusted hunting scope.

How long will the batteries last in the field?

The two 16340 rechargeable batteries provide approximately 2 hours of runtime at 25°C. You can extend this by using the auto-shutoff feature (selectable at 5, 30, or 60 minutes) when the optic is idle. The batteries are hot-swappable, so you can rotate in fresh cells without powering down the unit.

What's included with the C35 V3 for charging and connectivity?

The optic charges via USB-C, so you can recharge in the field, at camp, or at home. It connects to your smartphone through the BurrisConnect app, which allows real-time video streaming, photo and video capture, and remote control of key settings—all without removing the optic from your rifle.

Can I customize the image display, and what happens in complete darkness?

Yes. You can select from five color palettes (White Hot, Black Hot, Red Hot, Green Hot, and Blue Hot) to optimize contrast for your hunting environment and personal preference. The rotary dial control system is specifically designed to operate intuitively in total darkness, so you can navigate and adjust settings without any light source or visual reference.
