The Vortex Diamondback HD 8×42 binocularĀ is one of our all-time favorites for a quality binocular at a reasonable price, and is a top-seller in our store.

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 Diamondbacks maintain an easy weight. The large center focus wheel allows the user to achieve quick, precise focus, even when wearing gloves. Includes GlassPak binocular case and harness.
