Features of Styrka 10x42mm S9 Roof Prism Binocular:


  • EXTRA-LOW DISPERSION (ED) - Objective lenses virtually eliminate chromatic aberration, and high-grade SK-15 prisms increase brightness and contrast. This optimized optical system enables prolonged use in the lowest-light conditions
  • PHASE AND DIELECTRIC COATED PRISMS - Advanced coatings dramatically increase light transmission through the prism system for bright, high-contrast images with better resolution, superior clarity and precise detail
  • SXL-MAX FULLY MULTI-COATED OPTICS GROUP - All lens surfaces are coated multiple times utilizing our 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
  • OPEN BRIDGE DESIGN - Ergonomic design allows fingers to wrap around the barrels of the binocular for improved grip, steadiness and one-handed use
  • 100 percent WATERPROOF - Fully sealed housing for performance in all conditions; submersion tested for 30 minutes in 1 meter (3.3 feet) of water
  • NITROGEN PURGED - Internal housing is purged of air and filled with dry nitrogen gas to prevent internal fogging
  • RUBBER ARMOR - Provides tough, durable external protection and a secure no-slip grip
  • TWIST-UP EYECUPS - Twist up or down for a custom fit to your eye, with or without glasses
