Binoculars

Not long after the telescope was invented, some bright fellow decided to put two telescopes together, reasoning that both eyes should be used when trying to see; and binoculars were born. Like modern cheap binoculars, these early types didn't work very well, so monoculars ("spyglasses" they were called) were the most popular style into the 19th Century. Improved optics finally overcame those early technical difficulties, beginning a steady increase in binoculars' popularity.

Today's binoculars, especially the discount binoculars at Overstock.com, are clearly ahead of monoculars or telescopes since they are available in more types. Most binoculars have a single focal length and magnification, but zoom binoculars are adjustable. For fishermen, beach lovers and sailors, waterproof binoculars are the way to go. Hunting binoculars feature camouflage exteriors and light-weight, foldable bodies for ease in carrying. The electronics revolution has added a couple of new twists to binocular models: night vision binoculars amplify ambient light to allow the user to see in the dark. Small digital cameras are now built into some binoculars, so the watcher can also capture the image.

Few tools come in more modes and models than binoculars, and few stores can offer a better price than Overstock.com. When you figure in the $2.95 shipping for an entire order, online shopping at Overstock.com has pretty much everybody beat.
