The Styrka 8x42 S9 Series ED Binocular is designed with top class optics that is well capable of producing super bright images in low light environment. The Extra-low Dispersion (ED) glass placement plays well in correcting the spherical aberration (blur images). Additionally the high density fine SK15 roof prism features high refractive index that restricts internal light diffraction to maximise brightness, contrast and resolution. The lenses are high dielectric coated and phase corrected (brightened) which further limits UV diffraction and light loss. The optical tube of these S9 binoculars are further coated with SXL-MAX anti-reflective coating which boosts colour rendering and creates crisp and sharp image with true color. Altogether of these features presents a magnificent viewing experience especially during low light density environment.
The Styrka 8x42 features open-bridge design which offers additional grip and helps to reduce hand fatigue. Nitrogen purged optical tube, O-ring sealed construction makes this ED binocular tougher against harsh outdoor conditions. Its quiet impressive how these binoculars gather almost the entire available light and performs exceptionally in very iffy weather conditions.
