I prefer the moveable/adjustable one pin sights over fixed multiple pin sights. 1) because I like the simplicity of 1 pin and 2 I only shoot to 30yds, so I zero it at 20 yds, and if I need to take a shot at 30, I just ease it up a bit and let it fly.


To answer your question, Cloud nailed it, the sights usually come with a sticker and that you mark your yardages at, 20, 30, 40 and you move the sight to the appropriate setting, its very fast and easy and just as accurate as a fixed sight.
