Guest, no it isn't complicated at all: load, aim and loose. Thats all there is to it. it can be expensive though, The Hoyt RX and the Hoyt GMX are the best recurve target bows currently in production. Either of them as Phot remarks above will cost you the thick end of a grand.

On the other hand if you want to hit the little yellow circle in the middle of the target every time, THEN it gets complicated :)
