The Barr & Stroud Savannah 8×56 is the optimum light gathering binocular in the range, the brightness and clarity of image truly has to be seen to be appreciated, words are not enough to describe the experience. Its 56mm objective lenses in combination with its 8x magnification makes this the model which passes the largest amount of light through to the users eyes, this is important if the observer will be using the binoculars in low light conditions such as dawn and dusk when wildlife are on the move, or looking closely at a birds plumage in dense foliage where the light is restricted. 8x magnification is also relatively easy to hold steady without the need for additional support, such as a tripod, monopod or hide-clamp, in most conditions. They are waterproof to a depth 1.5m of water for three minutes. Fully Multi Coated optics are standard features of the Barr & Stroud Savannah as are BaK-4 phase coated prisms.
