Magnification, or power, is one of the most important considerations in choosing a pair of hunting binoculars, but shouldn't be the only factor you use to make your purchase decision. To understand magnification, note that it is the first number in a binocular description, such as 10x40. In this case, it has a magnification power of 10, meaning that an object you are looking at will appear 10 times closer than it would to your naked eye. So a buck standing 500 yards away will appear 50 yards away through your 10x binoculars. It might seem logical to think the highest power binoculars are the best, but typically the higher the power, the more sensitive binoculars are to small movements. Consequently, very high power binos can be harder to use for some hunters. For most hunting under normal conditions, 8x to 10x should suffice.
