Overview
Styrka S9 15x56 Binoculars Kit - Advanced, extra-low dispersion (ED) optical glass provides razor-sharp images and superb color correction while dramatically increasing clarity during low-light situations. Phase coated prisms; Coating applied to one surface of the prism increases contrast and sharpness by correcting out-of-phase light. Abbe Koening Prisms; Prism design with a more direct optical path is ideal for large objective binoculars, improving performance and light transmission. 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. Ergonomic design allows fingers to wrap around the barrels of the binocular for improved grip, steadiness and one-handed use. Fully sealed housing for performance in all conditions; submersion tested for 30 minutes in 1 meter (3.3 feet) of water. Internal housing is purged of air and filled with dry nitrogen gas to prevent internal fogging. Provides tough, durable external protection and a secure no-slip grip.
