And it's stabilizer, [8D]

A stabilizer does several things really. First, it stabilizes the bow. Really though, it takes a long stabilizer to do this. This is why you see many competition shooters shooting extremely long stabilizers to do just that. That stabilizer counter acts weights of the bow to balance or counter balance the bow, again depending on the stabilizer.

Secondly, it takes vibration out of the bow. That is if you have one capable or adequate to do just that.
