The Visionary B4 range of binoculars provide excellent value for money featuring high quality BAK4 prisms and multicoated lenses with excelent definition and clarity, the B4 range has a model suitable for most applications.
BAK4 prisms ensure a brighter image throughout the range of magnifications by maximising light transmission. Efficient use of the light gathered is particularly important at high magnifications or when using smaller front lenses, as images appear darker.
A 12x magnification binocular is considered by many, the best suited binocular for plane and aircraft spotting as the high level of magnification allows good levels of detail to be observed over long distances. This level of magnification is usually considered the highest that can be used comfortably as a hand held instrument (higher magnifications usually benefit from tripod mounting). 12x magnification is also a popular model for various equestrian event viewing.
Best images with a magnification of this level will be achieved by tripod mounting.
