What Is FOC In Archery ? Comprehensive Guide To Calculate It

Archery is usually a sport of inches, which means archers frequently make tiny adjustments to their setup to improve their shot or overall performance. Optimizing your arrows is one way to improve your shot, and there are two approaches.

Recently, archers have examined an arrow’s front middle weight, or FOC. FOC is the factor that determines a lot of the weight of an arrow. But why is FOC in archery so significant, and is there anything as accurate as FOC?

Our article “What is FOC in Archery and how do you calculate it?” discusses its effect on your shot as well as how to calculate it. We also cover the concept of ‘desirable’ or proper FOC, and when it might be appropriate to grow it.

What Is FOC In Archery And Its Importance?

FOC in archery refers to an arrow’s middle weight front. The reason we talk about an arrow’s FOC is because arrows tend to have their weight concentrated within the front half of them, as a result of the arrowhead generally weighing more than the other parts of the arrow.

Consequently, the center of mass of your arrow is biased towards the front instead of being located at the center of the shaft (which would have been lifeless). So, the FOC of your arrow affects its flight and trajectory.

It is still unclear whether FOC in archery has a real impact. A given occasion or class should have a FOC with which the majority, but not all, of the expert archers can work. The majority of archers shoot at indoor tournaments with a much higher FOC than they do at outdoor tournaments, for instance. When arrows connect poorly (i.e., hit a bone on effect), bowhunters usually select a higher FOC, since this allows the arrow to sink faster into the target.

The majority of archers and experts on the subject advise you not to be too concerned about your arrow’s FOC. It can have a little impact on your performance, but it’s not the be-all and end-all.

How Do You Calculate FOC On Arrows?

Easton Archery has posted a component for calculating FOC on arrows. It can appear worried, but once you’ve gone through the process, it will become second nature.

To start off with, you’ll need to divide the arrow duration in . Find the balance point. The stability point is the level at which you could stability the arrow without trouble (typically in the direction of the front of the shaft). Subtract the distance from one stop to the center from the balance factor. Multiply this number by one hundred, then divide it by the length of your arrow.

FOC For Arrows: What Should It Be?

The ideal FOC for an arrow will vary depending on a variety of factors. The environment that the arrow is shot in is a crucial part of the equation, as is the way archery is practiced.

You’ll need around 8-11% FOC if you’re shooting discipline points, and 12-15% if you’re shooting broadheads with a hunting arrow. If you’re shooting with arms or with short arrows, you’ll probably need around 15%.

In addition, it is important to note that FOC must be maintained in a healthy balance. An FOC over 18% is unlikely to provide much gain and may also negatively affect the way your arrows fly.

It is also possible to overthink FOC in archery or place too much emphasis on it at first glance. FOC in archery has a significant impact on how your arrow flies, but most likely it will not affect your shot. Adjust it to optimize your arrow setup, and if you are unsure, keep it under 18%.
