How to Select the Best Compound Bow
In a compound bow, limbs are bent using a levering system of cables. This then provides the flex and power to eject the arrow.
Compound bows, unlike the recurve bow of the old-fashioned longbow, have stiff limbs. Since compound bows are not made of wood, they then have stiff limbs. When it comes to energy efficiency, the modern compound materials used in the best compound bows is a lot better than wood.
To counteract the extra stiffness of the bow there is a series of levers and pulleys incorporated in this high tech compound bow. Without these, it would be impossible to flex the bow at all. When launching the arrow you need first to draw the string back until it reaches a point where the peak weight is achieved and the energy is released.
The benefit of using a compound bow is that it is weather resistant. Wood is absorbent and so using a wooden bow in rainy weather can be entirely different from using it during sunny weather. When natural oil in wood evaporates due to hot climate, old fashions bows can crack.
In the 1960s, the first patent on compound bows was released. Many hunters have seen the great advantages of using a compound bow and so gave up on their old fashioned wooden bows. With compound bows, you have an efficient bow with increased velocity and accuracy.
People are not agreed on which is the best compound bow or the best materials used in bow construction. Aluminum, magnesium, and aluminum alloy similar to those used for aircraft construction are the materials used for constructing compound bows.
The limbs is where the strong of the bow lie and no energy is stored in the pulleys or the cables. Some of the important parts of the compound bow are the cams and wheels which must function smoothly to move the string. It is not really strings that are used in compound bows but a high efficiency poly ethylene cable that can hold great tensile strength. Since stretching decreases string efficiency, these cables are designed not to stretch. The old bows before used high tensile coated steel but today most compound bows use polyethylene construction for its cables.
IN a compound bow, the cams are responsible for the speed of the arrow. Different types of compound bows either contain a soft cam or a hard one. Softer cams are normally used by those who are learning archery.
For those who are interested in purchasing compound bows for their new interest in archery, a professional archer or an archery teacher will be your best source of information as to the best compound bow to buy.
