Performance is how well those features function. Performance is usually not stated in quantitative terms in the manufacturer’s literature. For that reason, some people conclude that performance is subjective. We firmly believe that rifle scope performance can be measured and our goal is to provide relevant performance information to our customers.
Optical performance: transmission, resolution, contrast, etc.
Mechanical performance: reticle subtension accuracy, tracking accuracy and repeatability, point of aim shift, durability, etc.
Following is a table that summarizes our conclusions about features, performance and entry level cost. We define terms in this table as follows:
Features include both optical and mechanical features.
Accuracy Performance includes both reticle tracking, point of aim shift over zoom range, and subtension accuracy.
Durability Performance includes primarily resistance of POA to recoil and impact damage.
Optical Performance includes primarily resolution, off-axis aberrations and veiling glare.
The recommended Entry Price range is also shown:
A red “High” entry means that ignoring this issue could be detrimental. The absence of a red entries means you have more flexibility in compromising features and/or performance for lower cost. “Low priority” doesn’t mean “no priority”. Even a “Low” entry deserves some care in selection.

Eventually, you will have to determine your budget. At this point, however, we recommend that you first read the sections below that best describe your type of shooting. Once you have a sense of the functions you really need, you can browse products and get a better sense of your price range.
In each of the sections below, we quickly analyze the most typical scenarios to determine which features and/or performance criteria should be important factors and which should have lower priority.
