Compound Bows – How to Choose the Right One?
Compound bows that make use of levering system of cables are the best you can get as these bends the limbs which is the lower and upper portion of the bow providing power and flex in firing the arrow.
Since limbs of today’s compound bows are not made from wood, it is stiffer in comparison to old fashioned longbows. In regards to energy efficiency, wood far beyond the modern compound materials used to manufacture compound bows of today.
The additional stiffness of the bow is actually counteracted by a series of levers and pulleys which is common among high tech bows. It’s impossible for you to flex the bow unless you got superhuman powers. As you draw back the string, you are gaining mechanical advantage and increased energy too until you get its peak weight and the energy is released to launch the arrow.
The fact that you can use the compound bow on any type of weather is yet another selling factor of it. Most of the wood is absorbent and thus, using the bow either in a rainy or damp weather can be completely different from using it under sunny and dry conditions. Indeed, the old fashioned bows are only used in hot climates and have a tendency to crack since natural oil in wood evaporates.
A man from Missouri has patented compound bows back in 1960s. And from that time onwards, it has caught the interests of hunters and archers to give up their old wooden bows. They’re more efficient and offering increased accuracy and velocity. There however are some arguments between hunters and bowmen on which compound bow is best and arguments to which materials should be used in constructing the bow. 3 of the very popular options are magnesium, aluminum alloy or aluminum which are all used in aircraft construction.
The strength of the bow basically lies on the limbs and without the stored energy in cables or pulleys. The construction of wheels and cams is vital as these should move the string and for that, they’ve got to function smoothly. Even though the term string is what still used even in today’s time, the latest bows aren’t using string instead, a highly efficient high modulus polyethylene cables that has the capability of holding immense amount of tensile strength. Some of the older bows used to have this high tensile coated steel but, the best compound bows nowadays make use of polyethylene construction for cables.
This is the reason why compound bows cost such amount.
