2nd Generation Argon/Krypton Waterproofing
While we still waterproof other optics with bone-dry nitrogen – technology pioneered by Leupold® – Select models feature our exclusive, proprietary Argon/Krypton gas blend. Its advantages are two fold: it nearly eliminates the effects of thermal shock, and the Argon/Krypton molecules are significantly larger than nitrogen molecules, reducing the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does. We pioneered riflescope waterproofing, and now with Argon/Krypton we’re exceeding the standards we set ourselves.
Twilight Max Light Management System
Light management means delivering usable light to your eye and forming a crisp, high contrasting image. Lens coatings are applied that maximize light transmission in blue colors, since your eye is more sensitive to blue in low light. Red colors are also maximized, since they dominate scenes in typical hunting situations and finally the balancing colors to develop the highest possible contrast. Glare is controlled with special mechanical structures. The end result, you can see antler tines in dark shadows long after the competition has gone home.
