Vortex 10x42 Viper HD Roof Prism Binoculars
The Viper HD 10x42 Roof Prism Binoculars feature premium optics and rugged construction in a tremendously compact, lightweight package. The Viper HD binoculars are an optical masterpiece, giving hunters, shooters and outdoor enthusiasts a premium option without the premium price tag. The HD optical system delivers stunning resolution, color fidelity and edge-to-edge clarity. Lenses with XR PLUS Fully Multi-Coating provide critical low light performance by enhancing light transmission to you for more game-spotting opportunities.
Optical Features
Vortex Viper HD 10x42 Roof Prism Binocular feature HD (High Density) extra-low dispersion glass that delivers impressive resolution and color fidelity, resulting in crystal clear high definition images. Vortex's proprietary XR Fully Multi-Coating is applied on all air-to-glass surfaces to vastly improve and increase light transmission. Multi-Layer Dielectric Prism Coatings provide bright, clear, color-accurate images while phase correction coating enhances the roof prism's resolution and contrast.
Construction Features
The Vortex Optics Viper HD binoculars feature waterproof O-ring seals to prevent moisture, dust and debris from penetrating the binocular to give you consistent, reliable performance in all environments. Fogproof argon gas purging prevents internal fogging over a wide range of temperatures. Exterior lenses are protected by ArmorTek, which is an ultra-hard, scratch-resistant coating that protects exterior lenses from scratches, oil and dirt. The rubber aromored exterior provides a secure, non-slip grip, and durable external protection. A lightweight, short-hinge design gives you improved ergonomics and handling so that you can keep on going after hours of exploring. From a physical size and weight perspective, these binoculars are one of the lightest, most compact, full-size binos on the market.
Convenience Features
Viper HD 10x42 binoculars feature adjustable eyecups that you can move up and down for precise, intermediate settings to maximize your custom fit for comfortable viewing with or without eyeglasses. A center focus wheel adjusts the focus of both binocular barrels at the same time and dials in your image for sharp viewing. A locking diopter adjusts for differences in a user's eyes; one is located on the right eyepiece. The Viper HD 10x42 is compatible with a tripod adapter, allowing use on a tripod or car window mount.
Celestron Basic Smartphone Adapter
The smartphone adapter connects your smartphone to your telescope, so you can capture images and video through the eyepiece. With its light rigid frame, this accessory allows you to connect any smartphone to any telescope eyepiece with an outside diameter of 45mm or smaller. The additional magnification provided by the eyepiece allows your phone to capture great images of the moon and planets.
Durable Construction
This smartphone adapter installs easily by clamping over the top of an eyepiece. The smartphone is held in position with the help of tightening knobs that securely lock your phone in place. Some large and/or bulky phone cases (including folio style cases) may need to be removed for the phone to fit in the adapter. The adapter stands up to rigorous field use thanks to its robust, durable construction with a metal body.
Vortex Logo Hat
Enjoy a fit that's just right for you with a high-quality cap and a design fitting for Vortex Nation. The Vortex Logo Hat (Black Camo) will have you rocking a sporty yet casual look that’s perfect for hunting season. Designed like a traditional baseball hat, it also features an adjustable back closure for a snug fit, a visor to shield your eyes from the sun, and is embroidered and made of cotton. Wash it by hand when it gets dirty from a day out on the field.
