Overview ：
The combination of magnification and objective lens ensures an ultra-wide 60° apparent angle of view and large exit pupil, with enhanced light gathering ability versus smaller comparable models. Added to these features are anti-reflection fully multi-coated optics and BK7 roof prisms which maximize light transmission through the optical path, producing bright and clear high-contrast images with accurate color rendition.
The housing is made of a lightweight and durable plastic that is wrapped in a protective black rubber armor. Accents on the armor promote a more secure grip, helping to increase its handling in cold and wet weather.The optical tube is O-ring sealed to an IPX6-rating making it dustproof, and submersible to a depth of 3.3' (1m) for up to one hour. The optical tube is also nitrogen-filled to be resistant to internal fogging during extreme changes in temperature and environmental conditions. Construction details such as a twist-up eyecup and a standard 1/4"-20 tripod mount add to the comfort and usability of the monocular.
Optical Performance:
● Moderate 10x power magnifies view while maintaining a generous field of view and wide exit pupil
● 50mm objective lens boosts light-gathering capability versus smaller lenses to ensure bright images, even in challenging light
● BK7 prism glass delivers a round exit pupil and a crisp and clear image with limited edge distortion
● Anti-reflection fully multi-coated optics produce views with improved color rendition, contrast, and clarity
● Ultra-wide 60° apparent angle of view minimizes the appearance of visible hand shake that is common when holding high-power optics
● 315-foot field of view at 1000 yards
● Fully multi-coated optics maximize light transmission to produce bright and clear high-contrast images with accurate color and improved resolution
Use and Handling：
● Large textured user-facing focusing knob is easy to find and manipulate without looking and even when wearing gloves
● Convenient twist-up rubber eyecups for comfortable use with or without eyewear 
● Standard 1/4"-20 tripod mount allows for hands-free use to reduce fatigue and hand shake that can interfere with viewings
● Long 21.5 mm eye relief helps to reduce eye strain and improve viewing comfort
● Wide 5 mm exit pupil will completely cover most pupils as they open and dilate as light fades
Construction Details：
● Textured rubber armoring with raised palm pads provides enhanced slip resistance in cold and wet weather
● Tethered lens covers offer maximum lens protection without the risk of losing them during use
