The reason I ask is because my tube just snapped off and I could continue to shoot accurately with just the peep sight. It continued to rotate perfectly and offer me a clear view of my pins. So my question is, what does the tube do? Thanks
The tube makes sure that your peep aligns itself properly every time you draw. In order to shoot accurately now, you'll need to go purchase another length of tubing.
Another option is to purchase a tubless peep and have your pro shop install it for you.
