Here, you're getting Burris's wildly popular BTC35 v2 Thermal Clip-on along with the Burris RT-3 3X Prism Sight. Let's start with the Thermal Clip-ona | Introducing new BTC35 V2, featuring better resolution, better connectivity, and a streamlined user interface that makes it one of the simplest thermal units on the market. The combination of 3.2-12.7x magnification and 4x digital zoom provides enough "muscle" for extended viewing distances, while the 400x300 pixel resolution allows you to quickly and confidently identify targets. The original BTC's 17Amicrom pixel pitch sensor is gone, replaced by an improved 12Amicrom sensor that provides enhanced performance with a smaller, lighter objective lens. Manual non-uniformity correction, adjustable contrast and adjustable brightness allow you to fine-tune the picture. The BTC35 V2 features better app connectivity than the original, allowing for real-time video streaming and photo capture capability along with remote control of numerous device settings. Even better, Burris went back to the drawing board to completely overhaul the user interface. The new graphic interface uses an intuitive menu navigation system combined with a rotary knob to make changes rapidly and get you back to the action faster. Along with the better controls, the V2 features additional color palettes and 10 unique and customizable reticles. Burris RT-3 3X Prism Sight When speed is of the essence (and when isn't it?), the BurrisA(R) RT-3 Prism Sight delivers lightning-fast targeting for short- and mid-range engagements. The Ballistic 3X reticle features bullet-drop compensation for accurate shots out to 600 yards, and the illuminated center circle makes picking up short-range targets quick and easy. And with 7 brightness settings, you'll always have the right reticle for the job. Thermal Clip-On: Attaches to your rifle scope in minutes, or can be used as a handheld unit 3.2-12.7x magnification wi
