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:
● High 12x magnification enables detailed observations of distant subjects
● Large 50mm objective lens diameter draws in copious amounts of light to boost its light-gathering ability in challenging conditions such as at dawn and dusk
● Compact BK7 roof prisms deliver 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
● 264-foot field of view at 1000 yards
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 11.0 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:
● Lightweight and impact-resistant plastic chassis
● Nitrogen-filled to be resistant to internal fogging when moving through extreme variations in temperature and conditions
● O-ring sealed to a dust and waterproof IPX7 rating
● Textured black rubber armor protects against impacts while providing a slip-resistant grip
● Weight: 350 g
