Overview ：
12x50 Monocular is designed as a highly portable field optic for long-range use even in challenging light conditions.
The combination of magnification and objective lens diameter ensures an ultra-wide 62° apparent angle of view and a 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. Despite its size and weight the performance capabilities of this optic, when combined with the standard 1/4"-20 tripod mount, make the Siege an ideal highly portable spotting scope in the field, at the range, or in a blind.
Easy to carry and use, these optical and design features result in an optic that presents an immersive observational experience in all light and weather conditions.
Optical Performance:
● Moderate 12x 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 62° apparent angle of view minimizes the appearance of visible hand shake that is common when holding high-power optics
● 173-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 17 mm eye relief helps to reduce eye strain and improve viewing comfort
● Wide 4.1 mm exit pupil will completely cover most pupils as they open and dilate as light fades
