Guide to Buying Precision Compound Bows and Their Accessories

The compound bow is a modern bow where pulleys are placed at the ends of the limbs to increase its power and through which the bowstring passes. These bows are popular in both sports and hunting. In this case, we present precision compound bows, which are typically longer from axle to axle to improve stability. In precision archery with compound bows, bows longer than 35 inches are typically used.


Riser

The riser is one of the most important parts of the bow as it supports all the other accessories and parts of the bow. The limbs, as well as the sight, arrow rest, stabilizer, etc., will be attached to the riser.

We can find three types of risers, according to their shape, for compound bows: Deflex, Straight, and Reflex. Their characteristics are as follows:

  • Deflex or concave: This is a riser where the hand support point is in front of the axis that connects the limb attachment bases. These bows are more reliable, accurate, and quiet. They transmit power better in the shot compared to the other two riser types.
  • Straight or neutral: In this type of bow, the axis connecting the limbs to the riser is at the point where the hand rests on the grip. Its characteristics are intermediate.
  • Reflex or convex: In this riser, the hand is behind the axis that connects the limbs to the riser. It has the potential to send more power to the arrow than the previous designs, but it requires more experience as the shot tends to be more unstable and somewhat noisy.

Top pulley and bottom pulley

The pulleys are located at the ends of the limbs and are positioned eccentrically. They help to tension the bow with greater power and reduce the force needed to complete the bow’s draw.

There are different types of pulleys or cams:

  • Round Wheels: They are smooth to draw and are quieter and more reliable, but they transmit less power to the arrow. They are commonly found in beginner and target bows.
  • Energy Wheels: They transmit more energy to the arrow and retain many of the properties of round wheels.
  • Speed Cam: With a more radial design, they store more energy and provide greater arrow speed. They are harder to draw and difficult to adjust. They can become unsynchronized, so it’s important to monitor their adjustment, and it’s recommended to always use them with mechanical releases.
  • One Cam: This is a combination of two pulleys, one eccentric and one concentric, which can be found in new-generation bows. It doesn’t require synchronization adjustment between the two pulleys during the draw.

Arrows for pulley bows

The arrows used for compound bow are suited for a specific draw weight. Depending on the power to which the compound bow is adjusted, you will need an appropriate spine or stiffness for that power. Typically, compound bow can be adjusted up to 70 pounds of draw weight, and in some rare cases, up to 100 pounds. Therefore, you will need the right arrows to shoot safely and avoid accidents during the release of the arrow, as it tends to flex based on its stiffness.

In precision compound bow archery, the draw weight usually ranges between 40 and 50 pounds, and carbon, carbon/aluminum, or pure aluminum arrows are used with the appropriate spine (stiffness), which is always indicated on the arrow to prevent confusion and possible accidents.


Arrow Rests

The arrow rest is an accessory where the shaft of the arrow rests before being shot. It is placed at the front of the window and allows for low friction between the arrow and its support, enabling it to be shot efficiently.


Stabilizer

The stabilizer on a compound bow is usually different from that of an Olympic recurve bow. Instead of having the characteristic “Y” shape, it eliminates one of the short stabilizers and is shot with a long stabilizer and a short one, coupled together using a “mono” type V-Bar, which provides much more stability and accuracy.


String and Cables

The string and cables are another of the most important parts of the bow, as they allow the bow to be drawn with the arrow and enable shooting. The strings are usually of high quality and strength, and the common materials are modern fibers like Kevlar. Additionally, the compound bow has two cables that help synchronize the pulleys, maintain tension in the bow, and reduce the strain on the string. The cables are typically made of steel, although they can also be found in other materials.


Quiver

The usual quivers for precision compound bows are typically waist quivers, which are different from hunting quivers for compound bows. They can be found in synthetic materials and textiles.


Wrist Sling

The wrist sling for the bow is essential as it provides proper support and prevents the bow from accidentally falling when the shot is made, as the bow tends to pull in the direction the arrow is shot.
