Steiner Military-Marine 7x50mm Binoculars - OD Green Porro Prism

The Steiner Military-Marine 7x50mm binoculars deliver professional-grade optical performance designed for maritime and tactical environments. Built with Porro prism construction and Sports-Auto Focus technology, these binoculars provide instant clarity from 20 yards to infinity without constant refocusing.

What Makes This Different

Steiner's proprietary Sports-Auto Focus system eliminates the need for traditional focus adjustments by maintaining sharp images across the entire viewing range. The 7x50mm configuration offers the optimal balance of magnification and light-gathering capability for marine conditions. Military-specification Makrolon housing withstands impacts that would damage standard binoculars, while the integrated rubber armor provides secure grip in wet conditions.

Key Features

• Sports-Auto Focus technology - sharp images from 20 yards to infinity
• 7x magnification with 50mm objective lenses for superior light transmission
• Porro prism design delivers true stereoscopic depth perception
• OD Green Makrolon polycarbonate housing resists impact and corrosion
• Integrated rubber armor coating prevents slipping and absorbs shock
• Waterproof and fog-proof construction rated for marine environments
• Individual eyepiece adjustment accommodates vision differences

These binoculars excel in maritime surveillance, wildlife observation, and tactical applications where rapid target acquisition matters. The auto-focus design proves particularly valuable during boat operations or vehicle use where constant vibration makes traditional focusing difficult. Nitrogen-filled optical chambers prevent internal fogging in temperature extremes from -20°F to +140°F.
