Bushmaster 10-30 X 50 Rubber armored Binoculars 

10 to 30 times , grey rubber armoured, multi coated ruby lens. Bushmaster 10-30x 50 binoculars employ Multi-Coated Optics helping to increase the amount of useful light coming into the binoculars, thus providing an image that is brighter, sharper and clearer. Having every single surface of lenses and prisms coated with light-enhancing chemicals, Bushmaster binoculars promise a light tranmission efficiency of up to 95%. In addition, most Bushamster optics are treated with a layer of Ruby Coating on top of the normal coatings. It protects user's eye from UV emission and further increases the light transmission. It offers brilliant, crisp daylight viewing and is especially suited for use over water, snow an in other bright conditions.
