Outfitted with low-dispersion glass, fully multi-coated optics, and phase-corrected roof prisms, the Sig Sauer 10x32 ZULU3 Binocular optical system produces bright and clear high-contrast images with true color fidelity across the entire wide field of view. Its 10x magnification allows for detailed observation of distant objects, while the visible hand-shake common with optics of this power is mitigated by the wide viewing angle. The 32mm objectives makes this a small full-sized optic that is still compact and lightweight enough to easily fit in most pockets or packs.
Its open-bridge design helps to reduce weight without sacrificing strength and provides a large surface area to hold, even with the compact housing. Rubber armoring helps to give protection from drops and impacts while helping to provide a non-slip grip. Designed for durability, the lightweight polymer chassis is nitrogen-filled and O-ring sealed for fogproof performance and makes it submersible to 3.3 ft for up to 30 minutes. Twist-up eyecups provide a custom-fit eye relief for use with or without eye-wear.
