Why Do Archers Let The Bow Drop

Ever wondered why archers let the bow drop after drawing it back? Well, the answer lies in the fascinating world of compound bows. These innovative tools blend tradition with cutting-edge technology, allowing archers to hold a high poundage at full draw and then experience a “let-off” that reduces the weight, giving them more time to aim. From the power and speed they generate to their compact design and adjustability, compound bows have become the preferred choice for many archers. But choosing the right bow and maintaining it properly are essential for a safe and enjoyable archery experience. So, whether you’re a seasoned archer or just starting out, the compound bow offers a unique and thrilling journey into the world of archery.

Why Do Archers Let The Bow Drop

1. Mechanism of a Compound Bow

When it comes to understanding the mechanics of a compound bow, there are two key aspects to consider: the system of cables, pulleys, and cams, and the concept of let-off and holding weight.

1.1 System of Cables, Pulleys, and Cams

Unlike traditional bows, which rely solely on the archer’s strength to hold the draw weight, compound bows are equipped with a system of cables, pulleys, and cams that assist in this process. As you draw the bowstring back, the cables and pulleys work together to multiply the force applied, allowing for a higher poundage to be achieved at full draw.

At the center of this system are the cams, which are oval-shaped devices that rotate as the bowstring is pulled back. The rotation of the cams serves multiple purposes. Firstly, it reduces the draw weight as the bowstring is being pulled back, providing the archer with a mechanical advantage. This reduction in draw weight is known as let-off and will be discussed further in the subsequent section. Secondly, the cams control the draw cycle’s feel and the overall performance of the bow, such as arrow speed and smoothness of the shot.

The cables and strings play a crucial role in this system, transferring the energy generated by the rotation of the cams to the limbs and ultimately to the arrow upon release. It is the combination of these components working together that provides the compound bow with its unique characteristics and capabilities.

1.2 Let-off and Holding Weight

Let-off is a defining feature of compound bows and refers to the reduction in draw weight that occurs once the bow is at full draw. Traditional bows do not have let-off, which means that the full draw weight must be held by the archer for the duration of the shot process. In contrast, compound bows reach a peak weight and then let-off to a lower holding weight, making it easier to maintain the aim for an extended period.

Let-off is expressed as a percentage, indicating the amount of weight that is reduced when the bow is at full draw. For example, a compound bow with a 70% let-off means that at full draw, the archer is only holding 30% of the peak draw weight. This reduction in holding weight allows for increased accuracy and precision, as the archer can focus on aiming without the burden of holding a heavy weight.

The actual let-off percentage can vary depending on the specific bow and its design. Some bows feature higher let-off percentages, while others have lower percentages. The choice of let-off is often a matter of personal preference and shooting style.

2. Key Components of a Compound Bow

To gain a deeper understanding of compound bows, it’s important to familiarize yourself with their key components. These components work together to create a functional and effective bow for archery.

2.1 Limbs

The limbs of a compound bow are responsible for storing and releasing the energy required to propel an arrow forward. Unlike the straight limbs of a longbow or the curved limbs of a recurve bow, compound bow limbs are much stiffer. This stiffness allows them to store more energy while still maintaining stability and accuracy during the shot. The limbs are attached to the riser and work in conjunction with the cams and strings to create a powerful and efficient shooting platform.

2.2 Cams

The cams, also known as wheels, are a defining feature of compound bows. They are typically located at the end of each limb and are connected by the bow’s cables. As mentioned earlier, the cams play a crucial role in the draw cycle, controlling the draw weight, let-off, and overall performance of the bow. There are several types of cam systems available, each with its own unique characteristics and benefits.

Single Cam: This type of cam features a single elliptical shape and is known for its simplicity and ease of tuning.

Binary Cam: Binary cams consist of two cams that work in synchronization with each other. This design helps eliminate cam lean and provides a smooth draw cycle.

Hybrid Cam: Hybrid cams combine elements of both single and binary cams, offering a balance between ease of tuning and performance.

Cam & ½: This cam system features one binary cam and one power cam, providing optimal efficiency and speed.

The choice of cam system will depend on personal preference, shooting style, and intended use of the bow.

2.3 Cables & Strings

Cables and strings are essential components of a compound bow, serving as the primary means of transferring energy from the cams to the limbs and ultimately to the arrow. These components are typically made of high-strength materials such as synthetic fibers, which provide durability and stability throughout the shot process.

Cables and strings also play a role in achieving proper synchronization between the cams. Properly tuned cables and strings ensure that both cams reach maximum draw length simultaneously, resulting in consistent arrow flight and improved accuracy. It’s important to regularly inspect cables and strings for wear and replace them when necessary to maintain optimal performance.

2.4 Riser

The riser is the central part of a compound bow and serves as the foundation to which all other components are attached. It is usually made of aluminum or carbon, providing strength, rigidity, and stability. The riser incorporates various mounting points for accessories such as sights, arrow rests, stabilizers, and quivers.

The design and construction of the riser can significantly impact the overall feel and balance of the bow. Different riser shapes and materials can alter the weight distribution and vibration dampening properties of the bow, thus influencing the shooting experience.
