The best Binoculars by far at a great price. Alpen has gone out of business so I didn't think Adorama but they did!

Quality glass at an affordable price.

My brother has a set of Alpen binoculars,and I was impressed with how clear they are, and how reasonably priced they are for the quality you get. Not to be outdone, I also got a pair. To date, I have only used them to check out the ducks and geese flying in the neighborhood, and am very pleased with my decision. I look forward to using them for deer and coyote hunting in the coming seasons.

A great deal for a bright wide field of view. Too bad they went out of business.

Because capturing every detail matters, the Alpen Rainier 10x42mm HD ED Waterproof BAK-4 Roof Prism Binocular is designed with high-definition ED optics that maximize light transmission, ensuring you don't miss a single ray of light, even under challenging lighting conditions such as flat-light, dawn, or dusk. This advanced binocular pushes the boundaries of optical excellence with its UBX multi-layer coatings, engineered to optimize light transmission for a brighter, clearer view.

Incorporating extra-large BAK-4 prisms, this binocular benefits from over six decades of Alpen's expertise in optical coatings. Each prism is treated with Alpen's proprietary SHR metallic and PXA phase coatings, delivering unmatched brightness, clarity, and color fidelity. This ensures that every image you view is not only bright and clear but also rich in detail and true to life.

Moreover, the Alpen Rainier 10x42mm binocular features large diameter lens elements throughout its optical system. This design choice enhances the field of view, providing a more comprehensive visual experience. The long eye relief is another thoughtful feature, making it comfortable for eyeglass wearers to use. This binocular is not just a tool, but a gateway to a world of vivid, detailed, and breathtaking views.

Alpen 10x42 Roof Prism Features

  • HD - High definition, ED - Extra low dispersion optical system
  • Extra large BAK-4 prisms with SHR metallic coating, PXA phase coating and UBX multi-coating provide exquisite optical performance
  • Magnesium body construction provides strength and shock resistant durability
  • A-lock diopter locking system keeps adjustment settings in place
  • Long eye relief for full field viewing when wearing eye glasses
  • 1.5 turns from close focus to infinity for quick image focus
