Vortex Optics Diamondback 10x50 Roof Prism Binocular

O-ring seals prevent moisture, dust and debris from penetrating the binocular for reliable waterproof performance in all environments while argon gas purging prevents internal fogging over a wide range of temperatures.

Fully multi-coated on all air-to-glass surfaces increases light transmission while phase correction coating enhances resolution and contrast.

Adjustable eyecups can be twisted up or down for comfortable viewing with or without eyeglasses.

Center focus wheel adjusts the focus of both binocular barrels at the same time while the diopter (located on the right eyepiece) allows the user to adjust for focus differences between each eye.

Rainguard, tethered objective lens covers, comfort neck strap, and deluxe custom-molded carry case are all included in the box.
