Zero Tech Optics Thrive HD Features The Zero Tech Optics Thrive HD is built around a 3 MOA green dot reticle a reticle color chosen because it aligns closely with the peak wavelength the human eye perceives making it more visible under bright daylight conditions than a standard red dot. Advanced shake awake technology automatically activates the optic the moment it detects motion meaning it is always ready to go without manual power-on and without draining the battery during storage. A battery life rated at 50 000 hours on a single CR2032 cell gives shooters years of use before a replacement is needed. Multi-layer AR lens coating is specially developed to minimize image distortion keeping the dot and the target picture clear and sharp. Built on the Shield RMSc footprint the Thrive HD offers widespread mounting compatibility across most compact pistols already cut for this popular standard. The aluminum housing is rated fog proof shock proof and waterproof standing up to the rigors of daily carry and competitive use. At only 0.67 ounces and 1.6 inches long the optic adds negligible weight and bulk to a compact pistol s slide. The sight ships complete with a moulded rubber protective cover lens cloth sight tool and three sets of mounting screws giving shooters everything needed for installation and day-to-day protection.
