With a magnification–objective lens configuration favored by professionals all over the world, the gray Hawke Optics 10x42 Frontier ED X Binoculars deliver bright high-contrast images with true-to-life color and crisp clarity even when observing from long distances.

These binoculars feature extra-low-dispersion (ED) glass with phase-correcting and dielectric coatings on the BAK4 prisms. Anti-reflection fully multi-coated optics round out the optical features, and when combined with the glass and prism systems produce bright and clear high-contrast images with accurate colors and enhanced clarity without distortion or fringing. The wide apparent angle of view presents an immersive observational experience to complement the impressive optical performance, while helping to minimize the distracting hand shake that is common when holding high-power optics such as these.

A fast-focusing mechanism runs through the full focal range in just 1.5 turns of the large center focusing knob, making finding subjects fast and tracking moving targets easy. Designed to stand up to a life lived outdoors, the optical tubes are nitrogen filled and O-ring sealed to give them a waterproof rating of IPX7 and make them fogproof even when moving through extreme temperature variations. The chassis is made from a magnesium alloy to make it lightweight and corrosion resistant. Hawke includes tethered front and rear lens caps to add an additional layer of protection in the field, with the ability to quickly react to glassing opportunities without fear of losing the caps.

Optical Performance

• Powerful 10x magnification brings distant subjects in close for detailed observation
  
  
• 42mm objective lenses improve light-gathering ability versus smaller objectives while helping to maintain a compact form factor
  
  
• Compact roof prism light path ensures a slim profile without sacrificing performance
  
  
• BAK4 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
  
  
• Extra-low dispersion (ED) glass lens elements produce bright and clear images with accurate color rendition and improved contrast, without fringing
  
  
• Phase-correcting and dielectric mirror prism coatings eliminate internal interference, light loss, and diffraction to improve clarity, resolution, and contrast
  
  
• Anti-reflection multi-coated optics maximize light transmission to ensure bright and clear images with accurate colors and improved contrast and clarity
  
  
• Wide 64° apparent angle of view helps to minimize the appearance of the distracting hand shake that is common when looking through high-power optics
  
  
• Generous 336' field of view at 1000 yards
  
  

Use and Handling

• Closed-bridge configuration offers a solid and stable platform for the focusing system
  
  
• Large, slip-resistant center focusing wheel is easy to manipulate in cold or wet conditions or when wearing gloves
  
  
• Fast-focusing mechanism runs through the full focus range in just 1.5 turns
  
  
• Right-eye dioptric correction allows for precise focusing even for those who normally require corrective eyewear
  
  
• 56-74mm interpupillary adjustment range allows easy use by a wide variety of people
  
  
• Twist-up click-stop rubber eyecups for comfortable use with or without eyewear
  
  
• Comfortable 15mm eye relief reduces eyestrain for easier viewing, especially during long glassing sessions
  
  
• 4.2mm exit pupil will cover most pupils as they open and dilate in low light to keep the entire scene in view at all times
