Product Description

Product Info for Styrka 15x56mm S9 Binocular

The S9 binocular series is Styrka's flagship, boasting optical performance second to none. The 15x56 model is the ideal product for the Western adventurer that wants the best and is not willing to compromise. The highlight of this series is the Extra Low Dispersion (ED) objective lenses that nearly eliminate chromatic aberration and the Abbe Koenig prism design that increases brightness and overall light transmission. This prism design is ideal for the large 56mm objective lenses and provides prolonged use at dawn and dusk that will help you determine if that Coos deer or elk in the distance is worth leaving camp for. Fully multi-coated optics with Styrka's proprietary SXL-MAX flat multi-coating and phase coated prisms increase light transmission through the entire optical path for bright, high contrast images with jaw-dropping clarity and resolution. On top of all this the S9 Series features an ergonomic open bridge design that provides an improved grip and increased steadiness. All models are fully waterproof and nitrogen purged for use in any weather condition. The 15x56 is the model of choice for the Western nature lover that is looking for world class optical performance designed specifically with long range glassing in mind.
