rifle scope question?
i don't understand the numbers for the scopes never did i wanna get the slug hunter scope from nikon for my 1100 but there are two versions 1 is a 1.65x36 and the other one is 3.9x40 what do these numbers mean i never got what they meant please help
Example: 4x20 The first number is the magnification, or how much larger the image appears when viewed through the scope: 4x means the image will appear 4 times larger... The second number x20 is the diameter of the front lens in mm. (the one you look into is called the eyepiece).
A third and often ignored factor is the exit pupil size. It determines how much light can pass through the scope... Simply divide the numbers: 4x20 scope, 20 divided by 4 = 5, the exit pupil of this scope is 5. Any less than 5 and the scope will be "dark" in some low light, any more offers little advantage because our eyes are only able to see about that much...
Hope this helps, Buck
