The lacrosse shot is a wildly varied thing. Over the course of a single game, players might be required to take shots ranging from 10 - 40 feet out. Sometimes these shots will happen while standing still. Other times, the player will be running. Some shots happen immediately after a pass. Others do not.
The combination of these elements is what elevates great lacrosse shooting to an artform. In order to become an effective and complete shooter, players need to develop a variety of tools for all of these game situations.
A crossbow is a weapon that has been used for centuries for warfare and hunting. It is similar in function to a compound bow or longbow, but is used much differently. In fact, you could say that the crossbow is a kind of cross between a rifle and a bow and arrow. A crossbow has a stock much like a rifle, but uses an arrow as the projectile. The user will pull back the string and lock it into place, notch a bolt, which is the equivalent of an arrow to a bow, and then use a trigger to fire the arrow.
