Designed and built to deliver outstanding performance in low-light conditions, the Steiner Optics 8x56 T856r Tactical Binoculars combine multiple technologies and features to ensure bright, clear, and crisp views for tactical and surveillance applications. Speaking to their tactical use, this model comes with an in-view non-illuminated reticle specifically designed to enable fast and easy estimation of the range to, and size of, subjects.

Their performance starts with the combination of moderate magnification and oversized 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 covers your 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 lens coatings, which are engineered to maximize light transmission through the light path. All of these features, when coupled with the traditional Porro prism design and exceptional eye relief, give you an immersive observational experience defined by bright and clear high-contrast views and accurate color rendition. Winged eyecups conform to your 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 T856r to withstand the rigors of the outdoors. These details begin with Steiner's Sports-Auto-Focusing System, which allows you 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. 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. Their 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.
