African bows tend to have a low draw weight and for hunting tend to be short....this allows stalking and firing from concealed positions. Larger bows would get tangled with vegetation.The low draw weight is compensated by getting close to the intended prey and by the use of poisoned tipped arrows. This usually have a small barbed arrow head bound to a foreshaft which is then fixed to the main shaft. This arrangement prevents the animal rubbing against objects to remove the entire arrow . The barbed head remains in place as the thinner, weaker foreshaft breaks, leaving the main shaft behind. The poison is not fast acting and requires the hunters to stalk the injured animal for many hours.
