The Nikon 10x42 Aculon A211 Binocular (BAA812SA) is an ideal device for hunters, birders, and outdoor enthusiasts who require an optic that delivers high magnification for detailed observations of distant subjects while retaining the ability to observe quickly on the go, without the bulk and weight of larger models.
The enhanced light-gathering ability offered by the 42mm objectives helps to ensure bright and clear views, even in challenging situations like at dawn or dusk, or when peering into the dense underbrush. Anti-reflection multi-coated aspherical lenses, made with environmentally-friendly Eco-Glass elements, complement the BAK4 Porro prism light path to deliver high-contrast images with enhanced depth of field without edge distortion, as well as accurate color fidelity. Despite its 10x magnification, this version of the A211 has a wide-angle of view that helps to offset the appearance of visible handshake that is common with high-power optics such as this, while presenting the user with spacious views.
The Aculon's sculpted rubber-armored housing is designed to fit naturally into the observer's hand and provide secure non-slip handling. It is offered here in a subdued black color. Twist-up rubber eyecups and a comfortable eye relief enable easy viewing without eye fatigue, especially during long observation sessions. The combination of image quality and user-friendly design makes the 10x42 Aculon A211 a natural option for long-range glassing.
