You can, and should, tune your bow with nothing more than your current arrows. You absolutely do not need to spend hours or money to do it, just a little time and effort. To say it takes money, elaborate equipment and huge amounts of time is either a weak excuse or ignorance.

I am constantly amazed at the number of "hunters" that don't care to know how their equipment works, how to take care of their equipment or know how to use it properly.
