What Do the Numbers on a Rifle Scope Mean?

Dec 23,  · In the case of a rifle scope, if you see the number shown on it, it denotes a specific term- magnification and diameter of the objective lens.

To be fair, all of these confusing numbers on a spotting scope are really easy to understand. Explaining the numbers on a spotting scope is very what is the percent increase from 16 to 20 once you look at an actual example.

Remember, the numbers on the left side on an x always represent the magnification power of a spotting scope, and numbers on the right side of how to get a free vpn account x show the size of the objective lens in millimeters.

This is something that you will most usually see. Even though this one looks a little bit different from the previous set of numbers, it is just the same. The number on the left side of the x represents the magnification power of 4 on this scope, and the number on the right side of the x means 32 millimeter objective lens.

Moreover, from the numbers given, we can conclude that this is a fixed scope — there is only one number on the left side, which represents the magnification.

This is just the magnification power of a scope written in short. Naturally, it means that the picture you are looking at appears 5 times bigger than what they really are. Now, we had two examples that mentioned objective lens: 80 mm and Now you know what this number is, but what does it actually mean? The larger the number, the larger the objective lens.

Most of the spotting scopes have If you go any further, you will not be able to see the picture. Although it may sound uncomfortable to have your eye that close to an eyepiece, do not worry. Spotting scopes are made with this the eye relief distance in mind, so eyepieces are designed so that you can comfortably set your eyes that near to the glass. The eye relief distance on spotting scopes is much more precise than the distance in some other scopes.

For example, rifle scopes used in some other sports normally have an eye relief of 4 inches, which makes sense, since you do not want to have your face that close to something that you shoot from.

Also, the magnification on rifles is not as high as magnification on spotting scopes. Eye relief distance is also very important for people who wear glasses. If you are wearing glasses that are very thick, it can push your eye further away from the eyepiece, and you might not get the full field of view. When you have it listed, you can calculate and understand the distance and the field of view much easier.

In general, 12 to 16 millimeters of eye relief work just fine for everyone, even those with thick optical help devices. Rather obvious, this is the total weight of a spotting scope. It is shown in kilograms or ounces. Spotting scopes are usually really heavy and almost impossible to have in your hands for longer periods of time.
