Raise binoculars to your eyes and you can see everything far away as if it was right in front of you. The quality of a pair of binoculars rests on their crystal clear visibility.
Binoculars bring the tiny colored creatures into better focus. All other things being equal, the larger the objective diameter, the brighter the image you see through the binoculars. The magnification factor tells you how many times larger the object will be magnified, a number of between 4 and 7 is ample for most applications.
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. How well your binoculars will serve you in low light conditions is described as twilight performance. Phase correction is a coating on the lenses that increases the sharpness, contrast and color saturation.
Using your binoculars outdoors will usually subject them to moisture. Despite all of your preventive measures, there will come a time when your binoculars are damaged.
