Product Description
Classic Roof-prism design combines with a 10X magnification for an optimal viewing experience.
- PERMAFOCUS Technology – Keeps distant objects permanently in focus, eliminating the need for constant adjustment.
- Nitrogen Purged Fog-Proofing – Nitrogen inside the scope ensures interior optical surfaces won’t fog due to humidity or rapid temperature change.
- Multi Coated Optics – Multiple layers of coatings on all lens surfaces increase light transmission and image brightness.
OPTICAL PERFORMANCE
- 10X magnification brings distant subjects in close for detailed observations
- 40MM objectives deliver bright and clear views even in challenging light conditions
- BAK4 roof prisms produce crisp and sharp views with a round exit pupil and help to maintain a slim form factor for easier handling
- Anti-reflection multi-coated optics maximize light transmission to improve image brightness, color rendition, and contrast
- 58° apparent angle of view approaches wide-angle and ensures the entire playing field stays in view so you don’t have to move your head around to catch the action while limiting the appearance of distracting hand shake that are common when holding high-power optics
- 305-foot field of view at 1000 yards
USE AND HANDLING
- Focus-free PERMAFOCUS SYSTEM
- Closed-bridge configuration
- Wide 56-73mm interpupillary adjustment range makes binoculars easy to use by a wide variety of people, including children and teens
- Twist-up rubber eyecups for comfortable use with or without eyewear
- 14mm eye relief
- 4mm exit pupil
PERMAFOCUS SYSTEM
- Optimized for distances of 150 feet (46m) or greater
- Relies on the user’s eyes to achieve focus instead of a mechanism to keep the view constantly sharp
- Eliminates the need to fumble with diopter rings or focusing knobs
- Makes sharing the binoculars easier than with manually focused optics
