Monocular are simple telescopes which are only half of a pair of binoculars. Binoculars repair is the last thing on the mind of a user as they purchase their prized tool.

Waterproof and fog-proof binoculars are now available.

A telescope allows the universe to come to you, in other words objects of long distance come closer, while a microscope puts small objects to become bigger so you can see. A good rule of thumb is, unless you are a private investigator or international spy, avoid buying a pair of binoculars with a magnification/zoom greater then 10x's. You can find binoculars in prices ranging from ten dollars to one thousand dollars.
The first number gives the power of the magnification and the second number tells the diameter of the objective lens in millimeters which measures its light gathering strength. If your application is bird watching, theater or sporting events, a low powered binocular will suffice in most cases. The average binoculars user should go for a pair having magnification between 7 and 9x.
Treat your kids to a pair of inexpensive binoculars to explore the natural world around them. The newer binoculars are very lightweight making them ideal to pack in your lightweight luggage.
