Steiner 10×42 Tactical Binoculars

Description

Built for long-range perimeter security and tactical reconnaissance, the Steiner 10×42 Tactical Binoculars provides a 315-foot field of view at 1000 yards (6.0-degree actual). The 4.2mm exit pupil and 17.4mm eye relief ensure clear daytime observation. A distant 41.9-foot close focus distance restricts this optic from inspecting nearby objects or trailside brush.

Phase-corrected BaK-4 roof prisms run broadband multi-coated optics to maximize light throughput and edge sharpness. Encased in oil-resistant NBR Long Life rubber armor, the Makrolon polycarbonate chassis measures 6.5 by 4.6 by 2.6 inches and weighs 28.1 oz (796.6 g). Nitrogen filled and water-resistant, it features a central focus wheel tracking to 41.9 feet (12.8 m), an expansive -5 to +5 diopter adjuster, and cylindrical twist-up eyecups.

Key Features of Steiner 10×42 Tactical Binoculars

Engineered for border patrol teams, tactical spotters, and defense personnel who require structural reliability under extreme operational handling. The Makrolon polycarbonate housing resists severe physical impacts, while phase-corrected roof prisms preserve high target contrast.

• Phase-corrected BaK-4 roof prisms maintaining edge-to-edge optical resolution
• Broadband multi-coated optical elements delivering authentic color saturation
• 315 ft field of view at 1000 yd (6.0-degree actual angle)
• 17.4mm eye relief with cylindrical multi-stop twist-up eyecups
• 41.9-foot close focus distance suited for mid- to long-range surveillance platforms
• Nitrogen gas purged Makrolon polycarbonate chassis with NBR rubber armor
• Heavy-duty 28.1 oz body with front 1/4-20 tripod adapter threading

BaK-4 Roof Prisms & Tactical Optical Throughput

Phase-corrected BaK-4 roof prisms eliminate internal phase shifts, preventing roof-edge diffraction and keeping contrast high when observing shadowy tree lines. Multicoated lens boundaries reduce stray internal reflections, yielding clear target definition across roughly 85 percent of the viewing field before minor edge roll-off begins.

Makrolon Polycarbonate Body & Mechanical Action

The Makrolon housing withstands up to 11 Gs of impact shock without shifting internal prism alignment, while the NBR rubber armor resists chemical exposure and dampens metallic clatter. The center focus wheel glides with grease-damped drag, and the diopter ring provides a wide five-diopter adjustment span.

• Central focus wheel turns with smooth, predictable mechanical resistance in sub-zero weather
• Nitrogen-filled seals prevent internal lens condensation during rapid thermal shifts
• Twist-up eyecups feature distinct mechanical click-stops to maintain correct eye relief
