Binoculars are often referred to by two numbers separated by an "x". For example, 8x32. The first number is the power of magnification of the binocular. With an 8x32 bino, the object being viewed appears to be eight times closer than you would see it with the unaided eye. 

The second number in the formula (8x32) is the diameter of the objective front lens. The larger the objective lens, the more light that enters and the brighter the image. Keeping this in mind think about what you primarily want them for. Prolonged viewing sessions may cause fatigue with high powered bino's and telescopes so consider a relatively low power of around 7x - 9x. 10x at the most. For shorter viewing times 12x, 16x, 20x and 25x are available. Many are tripod mountable, some even come with in-built mounts. See our Giant Bino's section below for these. Our high quality range includes zoom bino's, weather or water proof, marine, birding, sports, astronomical and compact such as our 8x25 ultra compact porro prism type to a giant like the 25x100FB, be it for boating, hiking, nature, sports, racing, birding, surveillance or any other type of outdoor activity we are certain to have a model to suite almost any need.
