With a magnification–objective lens configuration favored by professionals all over the world, the green Hawke Optics 8x42 Frontier ED X Binoculars deliver bright high-contrast images with true-to-life color and crisp clarity across its expansive field of view.

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 with the ability to take in large areas without having to move.

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 them 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

• 8x power magnifies view without sacrificing field of view or exit pupil
  
  
• 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 65° apparent angle of view presents a spacious field of view to more easily find and track subjects
  
  
• Generous 426' field of view at 1000 yards
  
  

Use and Handling
