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 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 their 10x magnification, this version of the A211 has a wide angle of view that helps to offset the appearance of visible hand shake 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. They are 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 10×42 Aculon A211 a natural option for long-range glassing.
