What should arrow spine be matched to?
bow draw weight
Spine strength must be matched to bow draw weight. If your arrows are too lightly or heavily spined for your bow, the “archer’s paradox” movements will be extreme, resulting in poor arrow flight and loss of accuracy. (It’s better to err on the stiff, or too heavily spined, side.)
What does Spine mean with arrows?
stiffness
The spine rating of an arrow is simply a measurement of its stiffness. The same Easton arrow comes in a variety of stiffness: the lower the number, the stiffer the arrow. For example, a 330 arrow is stiffer than a 500 spine arrow.
How do I know if my arrow spine is too weak?
So how can you tell if your arrow spine is too weak or too stiff? The best way to tell if an arrow is too stiff or too weak is to videotape the flight of the arrow. Watching the flight of your arrow, you’ll be able to see if the arrow is veering to the right (too weak) to the left (too stiff).
What is spine weight for arrows?
The spine number is a deflection rating that measures the distance an arrow flexed with an 880-gram weight that is suspended between rollers 28 inches apart. Some common spines are 350, 400, 500 and 600. The higher the number, the more flexible the arrow.
How do you know if your arrow is under spin?
The arrow must be 29″ in length and supported by two points, which are 28″ apart. The number of inches the arrow deflects or bends x1000, due to the weight, is the spine size or measurement of an arrow. Dynamic spine is how the arrow reacts from the stored energy of a bow as it is shot.
How do you find the correct arrow spine?
They use point weight, draw weight, and arrow length to determine your correct arrow spine. To use these charts, simply take your point and draw weight and correspond it with your arrow length. Where these two numbers meet on the chart should provide your proper arrow spine. Note* Arrow charts vary from company to company.
Which is stiffer an arrow or a spine?
The same arrow comes in a variety of stiffness: the lower the number, the stiffer the arrow. For example, a 330 arrow is stiffer than a 500 arrow spine. Depending on your draw weight, draw length, and arrow material, you’ll adjust your arrow spine accordingly.
Why is it important to match an arrow to a bow?
Arrow spine, arrow weight, and arrow length are all important factors in matching an arrow to a bow. These three things need to be matched so that you, the archer, have the best chance of hitting their target. This article will explain why these factors are important when matching arrows to bows and how they can vary and complement one another.
What happens to an arrow with a weak spine?
An arrow with a weak spine will continue to correct itself throughout the arrow’s flight by oscillating side to side. This is also referred to as the Archer’s Paradox. This effect is much stronger if you are not using a release aid but if you draw your bow by hand. That´s me shooting my recurve.
