However I know that one mans opinion is often not enough, and people will continue looking for more and more information before they finally decide to buy. Before you go looking for a pair of binoculars you need to sit down and decide what you will be using your new binoculars for.
You position your telescope to look at the Moon, you see craters, and find that soon as you go to call someone to take a look, they take a look and it is gone. Most binoculars are lightweight, portable, and very easy to carry. That s the reason why astronomers prefer monoculars.
An ounce of prevention is worth a pound of repair. In live theaters and concerts, audience members sitting in the back rows away from the stage use binoculars to get a better view of the stage. Looking at the moon on occasion with a telescope looks like snow has dropped on the surface of the moon.
Another important number describing binoculars is called field-of-view. Using your binoculars outdoors will usually subject them to moisture. One of the most significant advances in optics is in water and fog proofing.
Bird watching has been around for many centuries and will probably be around many more. Ideally, you are going to lug these babies around for 10 or 20 years, so get a good pair.
