Which Material Provides Better Arrow Vibration Dampening?

Choosing the Right Arrow for Vibration Dampening

When selecting an arrow for vibration dampening, it’s essential to consider the arrow’s spine, which is the stiffness of the arrow shaft. A higher spine arrow is stiffer and will vibrate less than a lower spine arrow. A general rule of thumb is to choose an arrow with a spine that is at least 10% stiffer than the bow’s draw weight. For example, a 70-pound bow would require an arrow with a minimum spine of 77.

FOC Balance for Reduced Vibration

Another crucial factor in reducing arrow vibration is the front of center (FOC) balance of the arrow. FOC is the percentage of the arrow’s weight that is located forward of the arrow’s center of gravity. To achieve optimal FOC balance, the arrow’s weight should be concentrated in the front 1/3 of the shaft. This can be achieved by using heavier arrowheads and placing the weight of the vanes or fletching in the front of the arrow. A well-balanced arrow will exhibit reduced vibration and improved accuracy.

Materials for Vibration Dampening

When it comes to choosing between carbon and aluminum arrow shafts, carbon is generally the better choice for vibration dampening. Carbon arrow shafts have a higher modulus of elasticity than aluminum shafts, which means they will absorb and dissipate the energy of the arrow’s vibration more effectively. Additionally, carbon shafts tend to be lighter and more durable than their aluminum counterparts, making them a popular choice among archers.
