Designed and crafted by Swarovski Optik, the sleek Z6i 2.5-15x56 Gen-2 Scope is equipped with High Definition lenses for superior resolution at high magnification and low lighting. The scope utilizes a slim 30mm main tube for an impressive 15x magnification, a 4W-I reticle, and SWAROLIGHT illumination with compact illumination controls and a tilt-sensor to determine when the rifle is not in shooting mode and automatically turns off illumination for battery conservation. With waterproof and fog proof technologies, Swarovski’s highest imaginable glass quality which allows 90% light transmission, and a SWAROCLEAN coating to ensure that water droplets, dirt, and bug spray can be washed away with ease, you can expect a bright and crisp image whether you hunt at dawn, dusk, or on a cloudy day.
