Hawke Frontier HD X 10x42 Binocular (Green)

Outfitted with a magnification and objective lens size favored by hunters, birders, and outdoor enthusiasts around the world, the Hawke Optics 10x42 Frontier HD X Binocular is packed with features to greatly enhance your glassing experience, including phase-corrected and dielectric-coated BAK4 roof prisms and anti-reflection fully multi-coated objective lenses. These work together to produce a versatile and capable optic optimized for long-distance observation, with bright and clear images and accurate color rendition. Additionally, its exceptional field of view will allow you to take in sweeping vistas or a playing field without having to move your head very much and greatly increasing your comfort and enjoyment. Coupled with the optical features are full-sized 42mm diameter objectives that draw in copious amounts of light to push their usability from the pre-dawn hours all the way through to dusk.

Complementing the optical performance are construction details that make this binocular durable and comfortable to use. The lightweight and durable magnesium-alloy chassis is protected by a green rubberized armor that is textured for a nonslip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions. A right-eye diopter adjustment and twist-up eyecups allow the binocular to be customized to most people's needs and can be comfortably used with or without eyewear. Protecting the objectives and eyepieces are tethered caps that come off fast for easy reaction to glassing opportunities without the possibility of losing them.

Optical Performance

High 10x magnification brings distant subjects in for close viewing and identification

42mm objective lenses provide the light-gathering capability required for enhanced low-light performance without the associated bulk and weight of larger lenses

BAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortion

Dielectric prism coatings boost internal surface reflectivity to greater than 99% for maximum light transmission through the prism with minimal loss and diffraction and improved contrast and clarity

Phase-corrected prism coatings reduce internal interference to improve contrast, clarity, and resolution

Anti-reflection fully multi-coated lenses maximize light transmission for bright and clear images with accurate color rendition

Water-repellent exterior lens coating allows water to bead and run off to ensure clear views in inclement weather conditions

Wide 64° apparent angle of view helps to minimize the appearance of distracting hand shake that is common when holding high-power optics

336-foot field of view at 1000 yards

Use and Handling

Closed bridge configuration offers a stable platform for the internal focusing mechanism

Fast focusing system runs through the minimum focus distance to infinity in just 1.5 turns to make acquiring subjects fast and tracking moving targets easy

Large slip-resistant center focus wheel is easy to manipulate in cold or wet conditions or when wearing gloves

Right-eye diopter adjustment enables users to compensate for optical prescription for sharper views

Wide 56-74mm interpupillary adjustment range allows easy use by wide variety of people

Twist-up click-stop eyecups for comfortable use with or without eyewear; removable and replaceable

15mm eye relief improves viewing comfort and reduces eyestrain during long glassing sessions

Comfortable 4.2mm exit pupil will cover most pupils as they open and dilate in low light
