If the bow sight has a "gang" adjustment lower the whole site housing.

Center your 20 yard pin dead center of the housing. Then use the gang adjustment to sight in the 20 yard pin. After it is set, go onto 30, 40 etc.

Most shots are around 20 yards so when you hit your anchor you want to be already looking through your peep and through your 20 yard pin and concentrating on your target, not lining up your peep with your pin.

If you have no gang adjustment, I guess uhhhh.... Just ignore me
