High power binoculars are considered to be any binoculars that have a magnification power in excess of 10X. This number is determined by checking the numbers supplied on the pair of binoculars and is distinguished by the first number followed by an X; in other words a set of binoculars labeled 12X72 would indicate a magnification of 12 times what would be normally seen with the naked eye. High power binoculars are generally selected for viewing sports, reconnaissance, bird watching, and hunting where viewing things clearly at a long distances is necessary. The second number that is provided on the binoculars is the diameter size of the lens, and this will impact the brightness of the binoculars.

A wide variety of high power binoculars can be reviewed and/or purchased by visiting a number of specialty distributors on the web. A simple search for "high powered sports binoculars" recently generated over 6 million results on Yahoo, so the ability to find a vast array of suppliers and price points for the pair that you would like to purchase or investigate will be numerous. Company's that specialize in the sale of optics will often be providers of high power binoculars offering various brands including Carson, Bushnell, Nikon, Yukon, Magnacraft, and a host of other fine brand names.

There are drawbacks to getting a set of high power binoculars; and the biggest drawback is probably the fact that when using a hand-held pair, minor vibrations in your hands will be magnified as well and as the image. Without keeping the binoculars perfectly still, they will tend to blur if an assistance device is not use in connection with the binoculars. One such device that is available as an accessory for the binoculars is a tri-pod, and one that wishes to use exceptionally high powered binoculars should seriously consider purchasing this accessory along with the binoculars.

Another drawback of purchasing high power binoculars is as one increase's the power level, the area of the aperture decreases. This results in less light being collected and the view of the subject matter will tend to be darker. The faster the lenses in the binoculars to counteract this problem: the higher the cost of the pair of binoculars. Additionally, the field of view is decreased at higher power levels.

Your individual choice of a particular pair of high power binoculars will depend on your budget. One will have to balance the total cost of the binoculars desired based on magnification, brightness, field of view, and other factors like compatibility with wearing eyeglasses if appropriate. The binoculars will only be as good as the optics that they use, so expect a high correlation here between the quality of the sports binoculars and their price.

I would like to mention once more that the web is a wonderful tool for narrowing down the selection of which brand, style, and type of high power binoculars that you may wish to review before physically going to a store to review the binoculars in person. Reviewing in person does not mean that you are required to buy from the store, so remember if you can obtain a better price for the item on-line, and then by all means, make your final purchase after review on-line.
