the Pros of Using a Compound Bow

By Bart Icles

The compound bow is a bow unlike other known bow such as the recurve bow, longbow, or the crossbow of past and present eras. It uses a levering system composed of cables and pulleys (cams) used to bend a much stiffer limb made from aluminum or magnesium. It is this stiffness that sets the compound bow very far apart from the traditional bows. It's a more superior piece of product ingenuity and technology, and gives top performance in terms of accurateness, speed, and distance.

But like the world's vast array of man-made products, technologically advanced products or not, there will always be its advantages and disadvantages in its usage.

The first clear advantage the compound bow has is that it offers the archer to draw the bow without much effort, thanks to the cables and pulleys incorporated in it, and can therefore allow the archer to take a longer and steadier aim at the intended target. A drawn bow's weight increases to a peak and then eases or "lets off". The let-off ranges are from 65% - 80% for most compound bows. "Let off" is a term describing what occurs when the cam rolls all the way around. A drawn string turns the cams; it exerts enough force to compress or bend the limb, and once this happens there is only minimal effort or only least force is needed to keep it bent.

Aside from this, the compound bow is not affected much by temperature and humidity changes. It is highly resilient to extreme hot or cold temperatures, and moisture unlike other bows made out of natural materials.

The pulley system may include a form of rubber-coated block that act as stop points, or draw-stops that provide some kind of "barrier" to let the archer know he has reached his draw optimum level. These can also be adjusted accordingly as needed by the archer to achieve a consistent anchor point and exact amount of force influencing arrow shot after shot, thus increasing one's accuracy.

Pulley (cams) designs are divided into two types, the "soft cam", and the "hard cam". The former will speed the arrow toward the target slower compared to the latter. Soft cams are suited for novice archers, while the advanced archers may prefer the hard cams to gain more speed. Compound bows can have a variety of cams fitted to it to help improve the archer's performance.

While the compound bow may have undergone a lot of technical changes to it, it still demands respect and dedication from the archer - from the young to the old, from beginner to the accomplished at any time, place, and event it is being held, aimed and drawn. - 16887
