Already a 60+ year masterwork of ruggedness, clarity and light transmission, the Elite gets a significant performance upgrade this year with the addition of ED Prime glass. Fully multi-coated and featuring XTR technology, our Advanced Fusion Hybrid Lens system delivers 99.7% light transmission per lens. The result is unmatched edge-to-edge clarity, contrast and color-true imagery - now pushed to the highest levels with the use of ED Prime Glass. RainGuard HD coating eliminates lens fogging, boosts brightness and scatters moisture even faster than original RainGuard. Elite binoculars are also 100% waterproof,* fogproof and built around a tough, lightweight magnesium chassis for reliability in the most extreme conditions.
