The differences between carbon and aluminium arrows include price, precision, weight and durability. Carbon arrows are more expensive, heavier and last longer than aluminium arrows. However, aluminium arrows are precise and quiet in flight.
A carbon arrow is heavier and is not affected by wind drift. Due to the harder nature of the carbon material of the shaft, the arrows do not bend, which means that they last for a long time.
On the other hand, aluminium arrows are readily available and can be straightened if they bend. They make little noise in flight, which reduces the probability of scaring the prey away.
