SIG SAUER ZULU4 HD Marine 10×42 Orange Binocular

Marine-Ready Clarity in a Versatile 10×42 Format

The SIG SAUER ZULU4 HD Marine 10×42 binocular is designed for boaters, coastal observers, wildlife watchers, hunters, and outdoor users who need a clear, durable optic in changing conditions. This exact high-visibility orange model is manufacturer part number SOZ40001OR with UPC 798681736393. Its 10× magnification offers useful reach without the narrower view and increased hand movement associated with higher-power binoculars, while the 42 mm objective lenses provide a practical balance of brightness, size, and weight.

SIG SAUER pairs high-definition, high-transmittance glass with proprietary lens treatments to improve resolution, manage reflections, and protect exposed optical surfaces. The binocular’s magnesium frame is wrapped in rubber armor for grip and durability, and its IPX7 waterproof and fogproof construction prepares it for spray, rain, humidity, and rapid environmental changes.

Optical Performance

• 10× magnification: Provides detailed viewing at distance while remaining manageable for handheld scanning and general observation.
• 42 mm objective lenses: Gather useful light without the size and weight of a larger 50 mm binocular.
• Schmidt-Pechan prism system: Supports a compact roof-prism design with a straight, easy-to-handle profile.
• 60-degree apparent field of view: Gives the user a broad viewing experience for locating markers, wildlife, boats, or terrain features.
• 16 mm eye relief: Works with the two-position twist-up eyecups to help users establish a comfortable, repeatable viewing position.
• 1.8 m near focus: Allows observation of nearby subjects at approximately 5 feet 11 inches as well as distant objects.

Protective Lens Technologies

SpectraCoat is SIG SAUER’s broadband anti-reflective treatment, engineered to reduce surface reflections across the visible spectrum and support efficient light transmission. LensArmor adds abrasion resistance to help protect the exterior glass from routine handling and transport. LensShield uses an oleophobic surface treatment that sheds water, oils, fingerprints, and debris, helping the user maintain a clean sight picture in wet or dirty conditions.

These treatments work with the ZULU4 HD glass to support brightness and detail from early-morning observation through the fading light of evening. They also make the binocular easier to maintain after exposure to spray or frequent handling.

Built for Water and Field Use

The reinforced magnesium housing provides a strong foundation without excessive weight. Rubber armor improves traction when hands or gloves are wet and adds a protective exterior around the body. The bright orange finish is easy to locate among dark boat equipment, brush, or packed gear, while the included floating neck strap provides additional security around docks and open water.

A redesigned focus wheel with a precision-contoured overmold supports fine focal adjustments. The non-locking diopter offers a ±3 adjustment range for balancing differences between the user’s eyes. Interpupillary distance adjusts from 56 to 70 mm, allowing the barrels to align with a range of face shapes and viewing preferences.

Tripod-Compatible Design

For long observation sessions, the ZULU4 HD Marine can attach to a compatible tripod adapter through its standard 1/4-inch-20 threaded insert. A supported binocular reduces hand fatigue and keeps the image steadier during harbor watching, wildlife surveys, range spotting, or extended glassing from a fixed position. A tripod adapter and tripod are not included.
