Discount Binoculars. Lowest UK prices on a full range of Binoculars. RSPB, Opticron Viking, Hilkinson, and Canon. All at the best UK price. Binoculars or field are two telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most are sized to be held using both hands, or mounted on a tripod, or binocular clamp in a bird hide.
