Compact but outfitted with a powerful magnification for making detailed observations of distant subjects, the green Hawke Optics 10x42 Endurance ED Monocular is an ideal companion for your glassing needs on the trail, at the stadium, or sightseeing around town.

Engineered for performance, the Endurance is made with extra-low dispersion glass, a phase-corrected BAK4 roof prism, and fully multi-coated optics to produce color-accurate high-contrast views without distortion or color fringing—so your distant subjects look crisp and clear with excellent resolution. Its apparent angle of view helps to minimize the appearance of the distracting hand shake that is common with high-power optics.

Designed for daily outdoor use in all weather and to make it easy to hold, the Endurance features an ergonomic and slip-resistant armoring with raised ridges to provide a sure and positive grip. A standard 1/4"-20 socket allows it to be mounted on most quick-release plates, heads, and photo/video/field tripods for hands-free use. The optical tube is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging if the weather turns or it takes an accidental spill in a stream or puddle.

Optical Performance

• Powerful 10x magnification brings distant subjects in for close observation
  
  
• 42mm objective lens boosts light-gathering capability versus smaller lenses to ensure bright images, even in challenging light
  
  
• Roof prism light path ensures the optical tube remains thin for easier handling
  
  
• BAK4 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
  
  
• Phase-correcting prism coatings eliminate internal interference to improve clarity and contrast
  
  
• Extra-low dispersion glass virtually eliminates chromatic aberrations to reduce color fringing and halos
  
  
• Fully multi-coated optics maximize light transmission to produce bright and clear high-contrast images with accurate color and improved resolution
  
  
• Apparent angle of view approaches wide angle to minimize the distracting hand shake that is common when holding high-power optics such as these
  
  
• 304-foot field of view at 1000 yards
  
  

Use and Handling

• Large slip-resistant knob enables precise focusing, even in cold and wet weather or while wearing gloves
  
  
• Fast-focusing mechanism runs through the full focus range in just 2 turns
  
  
• Click-stop twist-up eyecup allows users to fine-tune their perfect eye relief
  
  
• 13mm eye relief
  
  
• 4.2mm exit pupil will cover most pupils as they open and dilate in low light and ensures the entire scene remains in view without vignetting
