Outfitted with innovative technologies and designed for easy carrying, the Steiner Optics 10x42 BluHorizon Binocular is ideal for the beach, trail, birding, or sightseeing around town.

Steiner's proprietary Autobright Lens Technology utilizes existing tech from the eyeglass industry to solve common problems—such as eyestrain, reduced contrast and clarity, and washed-out colors—when using magnified optics in extremely bright conditions. This photochromic adaptive system automatically dims the lenses in bright sunlight, much like popular transition eyeglass lenses that are clear when you're inside and darken when you go outside into direct sunlight. By reducing the excessive light, the lenses improve color rendition, contrast, clarity, and resolution while also making your viewing experience more pleasurable and comfortable. This adaptive system is complemented by a generous angle of view and short minimum focus distance. The former helps to minimize the hand shake that is often experienced when holding high-power binoculars and which takes away from the experience, while the latter allows you to make detailed observations of small birds at feeders or insects on flowers.

Its housing is made of a lightweight and impact-resistant polycarbonate material that is also temperature resistant—making it extremely durable over its lifetime of use. The chassis is wrapped in an oil-, petroleum-, and chemical-resistant synthetic nitrile-butadiene rubber (NBR) armor that offers improved grip security, especially in cold and wet weather.

Optical Performance

  • High 10x magnification brings distant subjects in close for detailed observation and identification
  • 42mm objective lenses boost light-gathering ability for improved performance in low-light conditions
  • Roof prism design produces narrow optical tubes for easier handing
  • Proprietary Autobright adaptive lens technology automatically dims the view in extremely bright sunlight to prevent eye damage and improve contrast, clarity, and resolution
  • Short 6-foot close focus distance enables detailed observation of small subjects like insects, hummingbirds, flowers, fauna, and flora
  • Apparent angle of view approaches wide-angle to help offset the distracting hand shake often experienced when holding high-power optics
  • 300-foot field of view at 1000 yards

Use and Handling

  • Closed bridge configuration provides a solid platform for the internal focusing system
  • Fast-Close-Focus system requires minimal rotation to take the binocular from its minimum focus distance to infinity for faster and easier focusing capability
  • Low-profile textured center focusing wheel is easy to use with either hand
  • Left-eye dioptric correction enables custom focusing for tack-sharp views
  • Fold-down rubber eyecups for comfortable use with or without eyewear
  • Wide 4.2mm exit pupil will cover most pupils as they open and dilate in low light

Construction Details

  • Lightweight and impact-resistant polycarbonate chassis
  • Chassis material is also temperature resistant to prevent the expansion and contraction that occurs with metal that can cause the optical components to move out of alignment and prevent being able to focus properly
  • Oil, petroleum, and chemical-resistant NBR synthetic textured rubber armor offers improved grip security, especially in cold and wet weather
  • IPX4-rated to be weather resistant against rain and snow
  • Winged eyecups block peripheral light to avoid interfering with the view for improved contrast and comfort
  • Compact and lightweight design is easy to pack, carry, and handle
  • Includes padded neck strap and nylon case
  • Broad -4 to 158°F (-20 to 70°C) operating temperature range
