The key to a long and useful life for your binoculars is to follow the simple steps to protect against the unexpected. When purchasing a pair of binoculars you want to know that you are purchasing the best possible pair.
There are the many popular ways people use binoculars with night vision. Knowing what you will be using the binoculars for will give you a specific type of binoculars to look for. More than a few people have been surprised to learn that binoculars go out of whack when bashed.
Remember you get what you pay for, so ensure you buy a good quality pair to prevent disappointment in the field. If you will be staying in one spot for a period of time then it might be to your advantage to consider mounting the binoculars on a tripod which would free up both hands and not require you to find the viewing area, refocus, and keep steady each time you pick them up. It is also useful in ranging an object that is not perfectly horizontal or vertical, enabling you to determine the range without tilting the entire binoculars.
Choosing a telescope is not an easy choice to make and is one that really needs research. You may not be planning on getting them wet, but things happen; you might trip and drop them in a mud puddle, take them out on a foggy day, or you might get caught in a freak rain shower. The only negative review I have to offer that the lens caps are cheap and are nowhere near the quality of the rest of the binoculars.
You will stare in the windows for hours and discover many thing that otherwise would be missed. The greater the magnification, the narrower the field-of-view.
