Watch the Limbs!
When you pull the trigger on your crossbow, it releases the string, which in turn causes the limbs to flex outward at a very high speed. Hunters must keep this in mind when they chose the location where they fire their crossbow. Branches, tree trunks, people or any other obstacles in the path of the limbs can cause serious damage to your crossbow, as well as severe injury to yourself or others.
Think about it - if the obstacle is on the opposite side of you, the force of the limb hitting that obstacle will drive the stock into your face, shoulder, or neck with great force. NEVER fire your crossbow if there are obstacles in the way of your bow's limbs.
