History of Compound Bows

The compound bow, a marvel of modern archery, has a rich history that traces its origins back to the 1960s. Invented by Holless Wilbur Allen, an engineer from Missouri, this innovative bow design was a groundbreaking departure from traditional recurve and longbows.

Allen’s patent in 1969 marked the beginning of a new era in archery, introducing a bow that utilized a system of pulleys and cables to bend the limbs.

The advent of compound bows revolutionized both archery and hunting in unprecedented ways. Unlike their traditional counterparts, compound bows offer greater accuracy, speed, and energy efficiency.

The pulley system allows for a “let-off” at full draw, reducing the amount of physical strength required to hold the bowstring back. This feature has made archery more accessible to people of all ages and physical abilities.

In the realm of hunting, the compound bow’s superior speed and power have proven to be game-changers. Hunters can now take down larger, faster game more humanely and efficiently.

The bow’s compact design also makes it easier to maneuver in tight spaces, a significant advantage in various hunting scenarios.

Today, compound bows continue to evolve, incorporating cutting-edge materials and technology. They have become the go-to choice for many archers and hunters, solidifying their place in the annals of archery history.

With their unparalleled performance and versatility, compound bows have truly redefined the art of the bow and arrow.

Basic Anatomy of a Compound Bow

Understanding the basic anatomy of a compound bow is essential for both novice and experienced archers. The compound bow is a complex piece of equipment, engineered for precision and power, and it consists of several key components that work in harmony to provide a mechanical advantage.

Firstly, the limbs are the flexible, elongated parts attached to the riser, the bow’s central framework. The riser is typically made from lightweight yet sturdy materials like aluminum or carbon fiber. Attached to the limbs are cams, or pulleys, which are the heart of the bow’s mechanical system.

These cams control the acceleration of the arrow and offer the “let-off” feature, reducing the draw weight when the bow is fully drawn.

The bowstring connects to the cams and is what you pull back to shoot an arrow. Some compound bows also feature additional elements like stabilizers, sights, and arrow rests, which further enhance accuracy and stability.

When you draw the bowstring, the cams rotate, flexing the limbs and storing energy. This system provides a mechanical advantage, allowing for higher arrow speeds and more accurate shots. The synergy between the riser, limbs, cams, and bowstring is what sets compound bows apart from traditional bows, offering a more efficient and user-friendly shooting experience.

Factors to Consider When Choosing a Compound Bow

Selecting the right compound bow can be a hard task, especially with the lots of options available in today’s market.

However, understanding some key factors and how they influence a bow’s performance can significantly simplify the decision-making process.

Draw Length and Weight

The draw length is the distance from the bowstring’s resting position to its full draw position. It’s crucial to select a bow with a draw length that matches your arm span for optimal comfort and accuracy.

The draw weight, on the other hand, refers to the amount of force required to pull the bowstring to its full draw. A higher draw weight translates to more power, but it’s essential to choose a weight you can handle comfortably to maintain accuracy and prevent fatigue.

Axle-to-Axle Length

Often abbreviated as ATA, the axle-to-axle length is the distance between the bow’s two cams. A longer ATA generally offers more stability, making it ideal for target shooting.

Conversely, a shorter ATA is more maneuverable, which can be advantageous in hunting scenarios, especially in tight spaces.

Brace Height

The brace height is the distance from the bowstring’s resting position to the deepest part of the bow grip. A shorter brace height can increase the bow’s speed but may reduce forgiveness, making it less tolerant of shooter errors.

A longer brace height, while potentially slower, offers more forgiveness, making it a good choice for beginners.

Let-off Percentage

Let-off refers to the reduction in draw weight when the bow is fully drawn, thanks to the cam system. A higher let-off percentage means you’ll hold less weight at full draw, allowing for a steadier aim, especially during prolonged aiming periods.

However, some purists prefer a lower let-off for a more traditional shooting experience.

Speed and Kinetic Energy

Measured in feet per second (FPS), the speed of a compound bow indicates how fast an arrow will travel. A faster bow can increase the chances of a clean pass-through shot when hunting.

Kinetic energy, measured in foot-pounds, represents the arrow’s penetrating power. Higher kinetic energy ensures that the arrow can deliver a lethal blow to the game, ensuring ethical hunting practices.

Maintenance and Care for Compound Bows

Owning a compound bow is a long-term investment that requires regular maintenance and care to ensure optimal performance and longevity. Whether you’re a seasoned archer or a beginner, understanding the intricacies of bow upkeep is crucial.

Regular Inspection and Cleaning: One of the first steps in compound bow maintenance is regular inspection. Check for signs of wear and tear on the limbs, cams, and bowstring. Look for frayed strings, cracked limbs, or any irregularities that could compromise the bow’s integrity.

Cleaning is equally important. Use a soft, damp cloth to wipe down the riser and limbs, removing any dirt or residue. Specialized cleaning solutions are available for more thorough cleaning, but always ensure they are compatible with your bow’s materials.

String and Cable Care: The bowstring and cables are vital components that require special attention. Use a high-quality bowstring wax to keep the string and cables lubricated, which prolongs their life and reduces the risk of fraying.

It’s advisable to replace the bowstring and cables every two to three years, depending on usage. Regularly inspect for signs of wear, such as fraying or stretching, and consider professional tuning to maintain optimal performance.

Proper Storage: Storing your compound bow correctly is crucial for its longevity. Always use a bow case that offers adequate protection against physical damage and environmental factors like moisture and temperature fluctuations.

When storing, keep the bow in a horizontal position to prevent limb warping. Also, it’s advisable to loosen the bowstring tension if you plan to store the bow for an extended period.


Overall, grasping the various kinds of compound bows is essential for beginners and experienced archers alike. If your interests lie in target practice, hunting, or a combination of both, this in-depth guide has shed light on important elements such as draw length, the distance between axles, and kinetic energy. Choose the right compound bow that aligns with your specific needs and enjoy a rewarding archery experience.
