A crossbow utilizes the energy stored as a result of pulling the string backward. Compound crossbow and recurve crossbows do this differently. Recurve bows are like traditional hand-drawn bows. The user pulls the string and it causes the 2 limbs to end, generating energy. After you’ve released the string, the stored energy is released forward to shoot the arrow.
Compound crossbows employ a system consisting of wheels and strings to cause the limbs to bend. With this system, crossbows can produce more energy and shoot arrows at a faster speed than recurve bows. However, the biggest downside of using compound crossbows is that they are quite difficult to maintain in comparison to recurve bows which come with several moving parts. If you are after maximum speed and power, compound crossbows may be the best option for you.
