TA31的eyerelief有限加上eyebox比较小，对眼睛位置宽容度不高，有时候reticle会模糊
TA11就好多了

TA31
Cons: Many can’t stand the short eye relief. I can understand that sentiment, but it doesn’t bother me too much. However, I can see where it could be problematic in awkward shooting positions. It also doesn’t make the scope particularly fast at heads up shooting. With practice, you can get used to it, but it certainly wouldn’t be my first choice in a 3-gun competition. Smaller exit pupil also means head position is more critical. In practice, it’s best if you get used to a consistent cheek weld so it is repeatable over and over. If you don’t do this, your point of aim can be slightly off. And if your heads gets in a REALLY bad position, the reticle will actually blur at best, or it will not be visible at all (because it is outside the exit pupil’s range). Going into a pitch black room with only the Tritium illumination is weird: Without a consistent cheek weld, you will find it hard to get the reticle in a position where it is not blurry with the TA31. |
