The first debate must focus on the quality of glass. Unfortunately, while the optical quality can be measured, there is no published specifications, you say what is the scope of the objectives of better quality than others. You need to compare a margin of manoeuvre for another, judging by it, sharpness and contrast targets. As a general rule, you should buy the best quality, scope, you can afford.

The quality objectives are not entirely by the glass itself, though. Lens coatings aid in contrast, translucency and reduction of glare, and there are words that describe the type of coating on a scope. An “iced”, the lens has a layer on the surface of the lens. A “full-Coated” objective has a coating on all surfaces exposed to the lens in the air, both front and rear. “Multi-Coated” targets have several layers of coatings on at least one surface of the lens. “Full Multi-Coated” targets have several layers on all lenses front and rear surfaces. The lens quality coatings may vary from one manufacturer to another, or even from one model to another by the same manufacturers, so you want to compare the image quality of individual sectors.

Another reflection when selecting a margin of manoeuvre is its construction. If you think your scope in bad weather, you want to make sure that the interior of the scope is filled with a substance such as nitrogen, is in the air at the scope of the hand and causing condensation on the inner surfaces of the goals. They also want to ensure that the scope of the body is resistant, or at least resistant against inclement weather.

Another important factor in your selection process is the increased volume. There are sectors of electricity magnification variable and fixed areas. A scope, that the net 3×30 magnification have a fixed 3 (30, the lens diameter, that we receive, in brief). A scope is highlighted 3-9×30 power is a variable, with the expansion adjustable 3 to 9 power power. Extending the scope is usually with an X, as in 3X. A volume 3X, the objective is to appear 3 times larger than it would to the naked eye.
