I see that installation is pretty straight forward, but does the Anchor Sight make shooting more complex?

Absolutely not!  In fact, it makes shooting your bow simpler and much more enjoyable.  It’s amazing how many archers have been conditioned into believing that a peep sight is necessary for shooting accurately and that you have to practice to develop a shooting form that you can consistently repeat.  A peep sight is simply a hole in your string, but it has been made a standard by the industry out of convenience and lack of a better option.  Now there is a better option!
