Parts of a compound bow

Arrow rest: An arrow rest is a device on a bow that supports and stabilizes the arrow during aiming and shooting.

Bow cables: Bow cables provide necessary tension and support to the bow limbs. They work in conjunction with the bowstring to store energy when the bow is drawn and help propel the arrow upon release.

Cable rod: A cable rod is a structural component that supports the bow's cables, ensuring they maintain proper alignment and tension. It helps guide the cables away from the arrow's path, preventing interference during the shot.

Cam: A bow cam is a rotating mechanism that helps control the bowstring's movement. It transforms the archer's effort into energy stored in the limbs.

Grip: The grip is the part of the bow that the archer holds while shooting.

Limbs: The limbs of a bow are the flexible parts that store energy when drawn, propelling the arrow.

Nocking point: A nocking point is the designated spot on a bowstring where the arrow nock is placed for consistent shooting.

Nocking Loop: A nocking loop is a small loop of string or material attached to a bowstring, providing an attachment point for the aid release.

Riser: The riser is the central part of a bow that connects the limbs, providing stability and support for the grip and accessories.

Sight: A sight is an aiming device that helps archers align their shots accurately.

Stabilizer: A stabilizer is an accessory attached to a bow that enhances balance and reduces vibrations during shooting.

String: A bow string is a strong, flexible cord that connects the bow's limbs, enabling the bow to launch an arrow when drawn.

String silencer: A string silencer is a device attached to a bowstring that reduces noise and vibration during arrow release.

String Stop: A string stop is a device attached to a bow that dampens string vibrations upon release, enhancing noise reduction and improving shot stability.

There are several types of shafts each using different materials or a combination of materials to make the shafts. To choose the correct shaft size, archers should look at charts made by arrow manufacturers. These charts are important for figuring out the best arrow specifications for your setup.

Wood shafts

Primarily used by recurve or longbow archers, these shafts are especially popular among traditional archers. They are often chosen for special recreational purposes. While they are not as durable or precise as other materials and are rarely used with high-poundage modern equipment, they are the least expensive option available.

Tubular aluminum shafts

Aluminum shafts are popular among bowhunters due to their exceptional durability and
lightweight nature. However, the thickness and diameter of these shafts must be matched to
the bow weight for optimal arrow flight and shooting safety. To ensure the correct size
selection, archers should consult commercially prepared charts provided by shaft
manufacturers.

Tubular carbon fiber shafts

These shafts have a smaller diameter and are lighter in weight compared to aluminum shafts
of similar strength. They are durable and popular for bowhunting, although they tend to be
expensive.

Tubular fiberglass shafts

These shafts are affordable but not precise. They are designed for lightweight recreational
bows.

Solid fiberglass shafts

These shafts are the most durable option, though they are heavy. They are commonly used for bowfishing and are well-suited for challenging shooting conditions, such as rocky environments and underwater settings.

Combination of aluminum and carbon fiber shafts

These shafts are popular for bowhunting because of their durability and precision. 

The arrow, regardless of shaft material, must have the correct stiffness to match the bow. As an arrow is released, the shaft bends before straightening in flight. Incorrect stiffness can lead to erratic and inaccurate arrow flights.

The plastic vanes or feathers on an arrow are referred to as fletching. Fletching creates wind drag providing stability and accuracy in flight.

Fletching will also cause the arrow to spin similar to a rifle bullet, which also improves accuracy. The most popular fletching is comprised of three or more feathers. One of the feathers will be a different color and is called the "cock" feather. The remaining feathers are referred to as the hen feathers. The type of arrow rest being used determines the angle between the bowstring and cock feather. Some archers prefer four fletches in which case there is no cock feather.

The nock is a slotted plastic tip located on the rear end of the arrow. The nock serves as a guide for fitting the arrow on the bowstring. There is a certain point on the bowstring where arrows are nocked. This point of the bowstring is called the "nocking point." We use a bow square to determine the point where an arrow on the rest would make a 90 degree angle with the bowstring. The nocking point would then be installed about 1/8 inch above the point. Fine tuning of this location is usually required.
