The Vortex Diamondback HD 10×42 BinocularĀ is one of our all-time favorites for a quality binocular at a reasonable price, and is a top-seller in our store. This binocular features an advanced roof prism optical design that incorporates high-density BaK-4 glass. The roof prisms feature phase-correction coatings and all lenses are fully multi-coated with anti-reflective compounds for maximum light transmission.

The Diamondback 10×42 offers a generously wide field of view to aid in finding and following fast-moving wildlife. Includes tapered rubber twist-up/twist-down eyecups to deliver a comfortable image to all users.

Built with a dedication to ruggedness, the Diamondbacks incorporate durable alloy housings and are covered in shock-absorbing rubber armor. The exterior armoring offers an ergonomic shape and is easily graspable regardless of the weather. O-ring sealed and argon-purged to make them dustproof, waterproof and fogproof. The 10×42 Diamondbacks maintain an easy weight. The large center focus wheel allows the user to achieve quick, precise focus, even when wearing gloves. Includes GlassPak harness case.
