Outfitted with high-density HD glass, fully multi-coated optics, and phase-corrected roof prisms, the Sig Sauer 8x42 ZULU5 Binocular optical system produces bright and clear high-contrast images with true color fidelity across the entire wide field of view. Its combination of a moderate magnification, glass, coatings, and wide 60° angle of view provide an immersive observational experience. The 42mm objectives draw in generous amounts of light that, when coupled with the proprietary lens coatings, enable this binocular to be used from the pre-dawn hours through to dusk, and in areas under a heavy canopy.
Designed for a lifetime of outdoor use by hunters, guides, and enthusiasts, the ZULU5 binocular chassis made from a lightweight, durable, and corrosion-resistant magnesium alloy. While this material reduces the overall weight to limit fatigue, for long glassing sessions the binocular can be mounted on a tripod using an optional adapter. Its optical tubes are nitrogen-filled and O-ring sealed for fogproof performance and makes it submersible to 3.3 feet for up to 30 minutes. Rubber armoring helps to give protection from drops and impacts while helping to provide a non-slip grip.
