The best compound bow is a bow that uses a levering system of cables that bend the limbs, that is the upper and lower portion of the bow, which provides the flex and power to eject the arrow. Limbs on a modern compound bow are stiff compared to those in a recurve bow or an old-fashioned longbow, because it is not made from wood. From the point of view of energy efficiency, wood is nothing like the modern compound materials that are used in the best compound bow today. The extra stiffness in the bow is counteracted by the series of the levers and pulleys that these high tech bows incorporate. Without them, it would be impossible to flex the bow at all, unless you were Hercules! As the string is drawn back mechanical advantage is gained and energy increased, until reaching the point where peak weight is achieved and the energy is released to launch the arrow.
Another advantage to the best compound bow is that you can use them whatever the weather. Most wood is absorbent, so using a bow in damp or rainy weather can be entirely different from using it under dry sunny conditions. Indeed, old fashioned bows used only in hot climates do tend to crack as the natural oil in the wood evaporates. The compound bow only dates back to the 1960s when a Missouri man applied for the first patent. Since then, most serious hunters and archers have given up their old-fashioned wooden bows for a compound bow. They are much more efficient, and offer increased velocity and increased accuracy. There may be many arguments between hunters and bowmen about which is the best compound bow, and also arguments about which are the better materials used in bow construction. This can be anything from aluminum, magnesium or an aluminum alloy that is used in the construction of aircraft. Click here www.archery-den.com/best-compound-bows/
The strength of a bow is in its limbs, without any energy being stored in either the pulleys or the cables. The construction of the cams and wheels is important, as these must move the string, so they most function smoothly. Although the term “string” is still used, all the latest and best compound bows don’t use string but highly efficient high-modulus polyethylene cables that can hold enormous tensile strength and are designed not to stretch, as stretching decreases the efficiency of the string. Some of the older bows used to use a high tensile coated steel, but the best bow today probably uses the polyethylene construction for its cables.
