What is a Compound Bow? [ Mechanics of Compound Bows, How They Work ]

In simple words, A compound bow is a type of bow that uses a system of pulleys or cams to reduce the amount of force needed to hold the bowstring back. This allows the archer to hold the string steady for longer periods of time, increasing accuracy and power. 

The compound bow has a long history, with the first patent for a compound bow being filed in 1966. Since then, the compound bow has become a popular choice for hunters, recreational shooters, and competitive archers alike.

How Does a Compound Bow Work?

The key feature of a compound bow is its pulleys or cams. These are round wheels located at the top and bottom of the bow’s limbs. 

When the bowstring is drawn back, the cams rotate, creating a mechanical advantage and reducing the amount of force needed to hold the string steady. 

This is known as the “let-off” or “holding weight.”

Let-off is the percentage of the draw weight that is relieved when the bowstring is held at full draw. 

Holding weight is the amount of force needed to hold the bowstring steady at full draw.

As soon the string is released, the cams rotate back to their original position, propelling the arrow forward with increased speed and power.

That’s the end of the first arrow thrown with a compound bow.

You can measure or get an idea about the holding weight by observing this info-table below-

If the Draw weight is –	And Let-off is-	The Holding weight will be-
50-70 lbs	80%	10-14 lbs
60-80 lbs	75%	15-20 lbs
70-90 lbs	70%	20-25 lbs

As an example: If the Draw weight of the compound bow is – 50-70 lbs – And Let-off is-80%- Then The Holding weight will be 10-14 lbs

How to Choose the Right Compound Bow For You?

Choosing compound bows will be ok for field archery, hunting, or competitive archery.

For beginners, it’s important to choose a bow that is easy to use and comfortable to hold. Single-cam bows are often a good choice for beginners, due to their simplicity and ease of use.

It’s also important to consider the draw weight or the amount of force needed to draw the bowstring back.

It’s a good idea to start with lower draw weight and work your way up as you gain strength and experience.

For more advanced shooters try the dual, or hybrid bow.  And always try to properly fit your size and shooting style. This can help to improve accuracy and reduce the risk of injury.
