Bushnell Engage BEN1050 10x50mm BaK-4 Roof Prism Binoculars

The Bushnell Engage BEN1050 delivers exceptional optical clarity with 10x magnification and generous 50mm objective lenses for superior light transmission. Professional-grade BaK-4 roof prism construction ensures edge-to-edge sharpness across the entire field of view.

What Makes This Different

BaK-4 prism glass provides 15% better light transmission than standard BK-7 prisms found in most binoculars at this price point. The fully multi-coated lenses maximize brightness and contrast while the nitrogen-purged housing prevents internal fogging in temperature extremes. Roof prism design creates a more compact profile compared to traditional Porro prism systems without sacrificing optical performance.

Key Features

• 10x magnification with 50mm objective lenses for 5mm exit pupil diameter
• BaK-4 roof prism glass construction for superior light transmission and clarity

Field performance excels in low-light conditions where the 50mm objectives gather maximum available light for dawn and dusk observation.

Weather-sealed construction handles rain, snow, and humidity without compromising internal optics during extended outdoor use.
