Steiner 2039 SHADOWQUEST 8x56 Overwatch Binoculars

Conceived, designed, and constructed for outstanding performance in low-light conditions when many animals are most active, the Steiner Optics 8x56 ShadowQuest Binocular combines multiple technologies and features to ensure clear and crisp views from first light through to twilight. Its performance starts with the combination of moderate magnification and over-sized objectives. At 56mm the objectives draw in the copious amounts of light required for seeing in low-light, while the 8x power produces both a large exit pupil and wide angle of view. A wide exit pupil ensures that the light leaving the eyepieces completely cover the user's pupils when they are fully dilated in low-light to take full advantage of the wide viewing angle. The optics are fully multi-coated with Steiner's proprietary Diamond Night lens coatings which are engineered to maximize light transmission through the light path. All of these features, when coupled with the traditional Porro prism light path, present the user with an immersive observational experienced defined by bright and clear high-contrast views and accurate color rendition. Winged eyecups conform to the user's face and eye sockets to block stray peripheral light and improve the contrast of the view while limiting distractions. Complementing the optical performance are construction details that allow the ShadowQuest to withstand the rigors of the outdoors. These details begin with Steiner's Sport Focusing System which allows the user to focus each eyepiece, just one time, and eliminates the need to refocus again regardless of how near or far the subject is — or if it is moving. Speaking to the low-light-use purpose, an innovative photoluminescent Lumiclip system is employed that glows with just enough light to be able to find them in low or no light. The chassis is made of a lightweight and impact-resistant Makrolon polycarbonate material that is wrapped in an oil, petroleum, and chemical-resistant NBR synthetic rubber armor that offers improved grip security, especially in cold and wet weather. Its optical tubes are nitrogen-filled and O-ring sealed to be waterproof to a depth of 16-feet, and resistant to internal fogging when moving through extreme temperature changes and environmental conditions. From dawn to dusk to piercing thickly wooded stands, the ShadowQuest binocular has been engineered to provide outstanding performance in the most challenging light and environmental conditions possible.
