The Compound bow was invented in 1967 by Holless Wilber Allen, from Missouri, USA. Originally developed for hunting, Allen spent six years developing this revolutionary bow. The compound bow relies on a range of cams and pulleys positioned at both ends of the limbs to provide its unique characteristics. Basically, as the bow is drawn to its full extent the “draw” weight is absorbed by this system of cams and pulleys. This means that at full draw the archer is required to hold significantly less weight on their draw arm, obviously allowing for a much more comfortable and controlled aiming. It also helps to offset the effects of fatigue, especially when a large number of arrows are being shot.
Similarly with the Recurve bow sights and Stabilisers are usually added to the Compound bow in order to improve accuracy. Also a special release aid “trigger” is normally used to release the string when shooting the bow.
