Eyeskey Dreamer-HD 10X42 Binocular

Overall

This binocular features phase-correction-coated roof prisms and anti-reflection multi-coated optics that produce bright and clear high-contrast images with true color rendition across the spacious and wide field of view. The 42mm objectives boost its light-gathering ability to improve views in challenging light such as at dawn and dusk or in foggy and cloudy weather without the bulk and weight of larger-objective models. Its wide apparent angle of view helps to mitigate the appearance of visible hand-shake that is often associated with holding powerful optics such as this and minimizes movement of the horizon line on rough or rolling seas to limit disorientation when using it on a boat. The combination of prisms, optical coatings, wide field of view, and comfortable eye relief allows users to enjoy a comfortable and immersive observational experience in most lighting conditions.

Complementing the optical performance are construction details that make this binocular durable and comfortable to use. It has a lightweight and corrosion-resistant reinforced polycarbonate chassis and is protected by black rubberized armor that is accented with textured palm pads to give it a secure non-slip grip. The optical tubes are nitrogen-filled and O-ring sealed to be waterproof and submersible, as well as resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A tethered one-piece ocular rain guard covers the eyecups as the binocular hangs around the neck and prevents rain and spraying water from filling them, and the objective lens caps can clip onto the neck strap to keep them safe from blowing overboard or being lost on the forest floor.

Optical Performance

Powerful 10x magnification allows for detailed observation of distant subjects

42mm objective lenses improve light-gathering ability without adding excessive bulk or weight

Roof prism light path ensures optical tubes remain thin for a compact form factor

Phase-corrected prism coatings reduce internal interference to improve light transmission, contrast, and resolution

Anti-reflection fully multi-coated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity

304ft wide field of view at 1000 yards

Use and Handling

Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism

Large slip center focus wheel allows for precise focus control, even while wearing gloves

Right eye dioptric adjustment collar helps to compensate for individual eye prescription

Twist-up rubber eyecups for comfortable use with or without eyewear

Tripod mountable with an optional adapter for hands-free use

Long 16.9mm eye relief helps to reduce eye strain and improves viewing comfort

Comfortable 4.2mm exit pupil will cover pupils as they open in low light to keep the full scene in view

Construction Details

Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditions

Lightweight and durable fiberglass-reinforced polycarbonate chassis

Chassis material is temperature resistant (-20℃~60℃), preventing the expansion and contraction that is common with metal, which can cause the optical components to move out of alignment over time and prevent sharp focus

Protective black armoring provides a slip-resistant grip, especially in cold and wet conditions

Plug-in fold-down objective lens caps prevent losing them during observation sessions
