Kowa 10×42 BD II XD Wide-Angle Binoculars

Description

Pushing an ultra-wide 7.2-degree actual field angle, the Kowa 10×42 BD II XD Wide-Angle Binoculars spreads an expansive 378-foot field of view at 1000 yards. The 4.2mm exit pupil and 16.5mm eye relief provide rapid subject pickup. Such extreme wide-angle geometry introduces minor peripheral field curvature near the circular field stop.

Dual Prominar XD extra-low dispersion objective lenses curb chromatic fringing, feeding phase-corrected Schmidt-Pechan roof prisms coated with C3 dielectric mirror layers and KR dirt-resistant coatings. The magnesium alloy chassis is encased in dark green rubber armor, measuring 5.5 by 5 by 2 inches and weighing 22.5 oz (638 g). Nitrogen filled and water-resistant, it features a fluid center focus dial tracking down to 5.9 feet (1.8 m), a right-eye diopter ring, and twist-up eyecups.

Key Features of Kowa 10×42 BD II XD Wide-Angle Binoculars

Prominar XD Glass & Ultra-Wide Geometry

Kowa’s twin XD objective elements eliminate secondary spectrum chromatic fringing, ensuring crisp feather and antler identification against bright sky backdrops. The 7.2-degree optical window provides exceptional situational awareness, with minor peripheral softness confined to the outer ten percent of the frame.

Magnesium Chassis & Fluid Focus Mechanics

The lightweight magnesium frame protects optical alignment from drop impacts while remaining light enough for all-day carrying. The internal center focus wheel glides smoothly across its travel with grease-damped drag, and the textured green rubber armor provides a secure, non-slip grip in wet weather.

• Internal central focus wheel turns smoothly without mechanical backlash or deadband
• O-ring sealed nitrogen chambers eliminate internal moisture condensation during sudden storms
• Twist-up eyecups lock securely in place to maintain correct eye relief for spectacle wearers
