Sunshade aldığım opticsbestbuy sitesinde durability(dayanıklılık)başlığı altında şu test yöntemini okudum ve paylaşmak istedim.
"Rifle Scope Durability
If you have ever taken one of our classes I am sure you have seen a gun dropped, thrown, kicked, or even buried. It happens! Guns are tools we use for many excuses but only one reason, to shoot. If you feel you need to baby your gun you are looking at the wrong website. But if you except the fact that your gun might get dropped and when it does happen you reconfirm your zero and move on then you are in the right mindset. Whatever scope you buy you need to do some test with the adjustments. Make sure you can shoot a square with it. It doesn''t have to be perfect but shoot two shots then move it left ten clicks, shoot two more. Move it up ten clicks, shoot two more. Move it right ten clicks, shoot two more. Lastly, move it down ten clicks and shoot two more. Your last two shots should be close to your first two. If not do it again and see if it is consistent. If your scope will not do it think about sending it back. Always make sure all scope screws are tight at least once a month if not every time you go to the range. You should hear and feel a "click" when turning the adjustments knobs."
Özetle dürbün bir kare çizebilmeli;önce iki atış yapın sonra 10 klik sola alın iki atış daha yapın, 10 klik yukarı iki atış,10 klik sağa iki atış ve 10 klik aşağı iki atış son iki atışın ilk iki atışın olabildiğince yakınında olması gerektiği yok değilse dürbünü geri yollamayı düşünebilirsiniz denmekte.
