How to Choose Binocular Magnification

1. Learn how magnification is measured. If you know nothing about binoculars, you can easily be confused by the numbers. For example, you'll see a pair that says it's 8x40. The eight is the magnification number and the 40 is the lens width, in millimeters. A magnification number of eight means that you see things through the lens as being eight times closer than you would if you were looking at them with the naked eye. If instead of a single magnification number, the binoculars have a range of say 7 to 12, that means the magnification is adjustable. This is usually done by turning a knob.

2. Decide what you're going to look at with your binoculars. A larger magnification number is not always best, since it limits the field of view. Therefore, only go as high as you need to to get a good look at your target. If you're looking at objects in nature that are relatively close but lack detail, a magnifying power of seven to 10 should be more than enough. However, if you're looking at faraway objects, like that mountain range or the moon and stars, go for 12 to 15. If you go any higher than this you'll want your binoculars to have a "close focus" option. Otherwise, you won't be able to see anything but a blob unless you look at things that are miles away.

3. Get a tripod. If you go with a magnification of 12 or higher, you'll need a tripod to keep your images steady. A tripod will also help to keep your hands and arms from tiring. Find a collapsible tripod so you can easily take it with you on bird watching and star gazing excursions.
