COMPACT BINOCULARS 

 PORRO PRISM BINOCULARS . this system was invented by a Snr.Porro of Italy. The optic design is well balanced. When viewed from either a low magnification to high magnification the visibility is bright & sharp. Compacts use the Porro Prism design on a smaller scale, giving the distinct advantage of both designs.
This is a high performance range of compact binoculars. They are a serious alternative to the larger Porro Prism binoculars and have the advantage of minimal size and weight and make them a perfect companion for walking expeditions and holidays.

OPTICAL COATINGS .These improve light transmission to the eye by reducing reflection internally & externally for a bright, crisp image.
FULLY COATED......All air to glass surfaces are coated. Fully coated lenses increase overall clarity and definition.
RUBY COATED......6 layers or more of multi coating consisting of varying colours & composition on the objective lenses. Ruby lenses filter out red light, making them especially good for viewing objects over water, snow or other bright conditions
MULTI COATED.............One or more surfaces of one or more lenses have been coated with multiple films, minimising light loss and improving overall clarity & definition.
A Binocular will usually be marked so that you know what to expect from it. Typical specifications are 8 x 30, 8 x 40 or 10 x 50. The first figure indicates the degree of magnification and the second, the diameter of the objective lenses, in millimetres. For most purposes, magnifications of between 6.5 x and 10 x will be most satisfactory. As magnification increases, the size of what you look at will appear larger, but any slight hand movements will also be exaggerated so that you may not be able to keep the binocular steady enough also, focusing will need to be more precise and the field of view may become narrower. The diameter of the objective lenses will control how much light the binocular can collect. In bright conditions the lens size will not be too important, but larger lenses will be able to maintain the brightness of the image even in poor lighting. Usually the greater the number of times that the magnification can be divided into the objective lens diameter, the brighter the image will be.
