Well that's great but what do the numbers (specs) mean?
The specs are Magnification Power x Lens Diameter.
So, for example, 10x32 means that the object will appear 10 times closer to you than the naked eye. A moose at 200 yards will appear like it's at 20 yards (200 divide by 10). Anything with a magnification power higher than 10 will amplify your hand movements and may make steady viewing a difficulty.
Lens diameter of our example is 32 millimeters. This determines how much light is let in. More light = brighter view, especially in low-light situations.
Coatings help reduce reflection and help ensure a clear and sharp image.
