The Aculon A211 Zoom is a universal pair of binoculars designed for a variety of outdoor activities including bird watching, looking at nature and hiking. With its multiple anti-reflection layers and wide-angle lens, it is possible to achieve a very clear image with a wide viewing angle. The use of aspherical lenses greatly reduces distortion at the edges of the lens.

The lightweight, rubberised body has great endurance and protects the binoculars from impact and rain. This way you won't have to worry about them, even while under harsh conditions.
