i do not believe that using sights is a must. my brother in law has never used sights with his compound. he shoots excellent. with practice he can even shoot long distances with his bow as well as i can with sights.

to say that he has no accuracy would be stupid. everyone mises. or has a lapse in form from time to time. if you can shoot without sights more power to you... ever hear of Danand Guy Fitzgerald.. they do not use sights.. or at least they did not for a long time.
