Bushnell Elite binoculars are the peak of technology with over 50 years of experience from the Bushnell Company and they can be easily compared in optical properties with other more expensive competitors. It does not matter if you compare Bushnell Elite binoculars to their competitors in image sharpness or light transmission rates in the dark, they can always keep up with them.

O-rings keep the housing waterproof and the insides of the magnesium made binocular is dry nitrogen filled which keep it fog proof even under extremely low temperatures. The exterior of Bushnell Elite binoculars is rubber coated to ensure slip free handling and protects the binoculars from minor impacts. Image sharpening is centrally adjustable and the adjustable oculars make the binoculars easy to use even for people with glasses.
