Features of Styrka 8x42mm S9 Roof Prism Binocular:
Extra-low dispersion (ED) objective lenses virtually eliminate chromatic aberration and high-grade SK-15 prisms increase brightness and contrast for an optimized optical system that enables prolonged use in the lowest light conditions
Advanced phase and dielectric coated prisms dramatically increase light transmission through the prism system for bright, high contrast images with better resolution, superior clarity and detail
All lens surfaces are coated multiple times utilizing proprietary SXL-MAX anti-reflective flat broadband coatings for maximum brightness and optimal color, sharpness and image contrast, while maximizing transmission across the entire visible light spectrum for true-to-nature color representation
Ergonomic open bridge design allows fingers to wrap around the barrels of the binocular for improved grip, steadiness and one-handed use
Fully sealed housing for waterproof performance in all conditions
Submersion tested for 30 minutes in 1 meter (3.3 feet) of water
Nitrogen purged internal housing to prevent internal fogging
Rubber armor provides tough, durable external protection and a secure no-slip grip
Eyecups twist up or down for a custom fit to your eye with or without eyeglasses
