Sig Sauer’s Zulu10 HDX Binoculars were specifically engineered to exceed the demands of the most elite hunters in the world. The Zulu10 HDX combines high-definition and high-transmittance glass lenses for ultra-high image resolution and optimal light transmission. With the help of Sig’s proprietary LensArmor, LenShield and SpectraCoat technologies, the image generated through the best-in-class Abbe Koenig prism is incredibly sharp from dawn to dusk. The rugged metal chassis and updated rubberized armor provide bombproof durability while maintaining unmatched in-hand comfort. To further improve in-hand comfort and adjustability, the locking diopter ring and main focus dial have been updated to sleek anodized aluminum with a textured rubber over mold. Featuring 3-position adjustability and an updated detent system, the Zulu10 HDX eyecups are designed to maintain their position throughout frequent movement in and out of bino harnesses.
