COMPACT ULTRA HIGH POWER ZOOM BINOCULARS 8-20x X25

These are NEW, BOXED with FIVE YEARS MANUFACTURERS WARRANTY

Brilliant to use for everything from hiking to birds, sport and plane spotting these brand new super compact binoculars (just over 4" high) come with strap, cleaning cloth, eyepiece caps, 5 year manufacturers warranty and weather proof case with easy carry belt loop. (phew!)

These really are neat enough to go anywhere, and versatile enough to give superb viewing for a massive range of subjects.

Many zoom binoculars have a small lever under one of the eyepieces, which usually works fine, except that to use it you are effectivly holding the binocular with one hand, and zooming with the other. Consequently stability is greatly reduced.

These have an absolutely superb design with the zoom control on a central top mounted dial - you can hold the binoculars rock steady with both hands AND zoom with MUCH more control than the old lever style!

What the numbers mean - 8-20x25

The 1st number is the magnification, the 2nd is the diameter of the front (objective) lens.
The larger the 1st number, the closer the subject will come, however as you increase power, you will also get less clarity, less width of view and more shake. As a rule, the higher the power, the shorter the time you can comfortably view through the optic. 8x - 10x is good for general use. Above 12-20x many people would need a tripod! The larger the 2nd number, the brighter the image will be, and the more detail and clarity you will see, however as you increase size, the binocular will become bigger and heavier, and so less portable.
This size, (8-20x power - 25mm diameter) produces a very compact, convenient optic, with very very versatile general purpose zoom range from 8x to 20x closer. 8x is comfortably hand-holdable, with a wide width or 'field' of vision, so subjects can be found easily, and viewed for a long time and 20x allows you to get 'right-in' to the action!
