What Does Ibo Mean In Archery? (Solved)

In order to quantify arrow speeds, the International Bowhunters Organization and the Archery Trade Association have developed precise formulae. IBO speed is evaluated by firing a 400-grain arrow with an 80-pound draw weight (+/- 2 pounds) and a maximum draw length using a bow with an 80-pound draw weight (+/- 2 pounds). The ATA speed is measured using a 70-pound draw weight (+/-) as a reference.
What is an IBO bow, and how does it work?

  • The International Bowhunters Organization (IBO) is an acronym that stands for International Bowhunters Organization. According to the International Bowhunters Organization, a standard for bows has been established, which is developed through a testing process. The IBO speed is obtained by firing a bow with a maximum pull weight of 80 pounds +/- 2 pounds and a draw weight of 80 pounds +/- 2 pounds. The weight of the arrow will be 400 grains, which is equal to 5 grains per pound of draw weight.

How is IBO calculated?

For example, the IBO speed of a bow is computed using a bow with a draw weight of 70 pounds and an overall length of 30 inches, as well as an arrow weight of five grains per pound of draw weight. A 70-pound draw weight would be firing an arrow weighing 350 grains (70 divided by 5 equals 350 grains).

What draw length is Ibo?

The IBO speed that is marketed for bows is tested at a 30″ draw length; therefore, if the draw length is reduced, the bow will lose speed; conversely, if the draw length is increased, the bow will gain speed. However, it is critical that shooters choose the draw length that is most comfortable for them rather than attempting to shoot at a larger draw length in order to obtain more speed.

The speed of an arrow is measured in feet per second, abbreviated as fps. Generally speaking, the greater the number, the quicker the bow is. Bows with a speed rating of 300 fps are significantly faster than bows with a speed rating of 290 fps. Bow makers indicate their speed ratings with the letters “ATA” (Archery Trade Association) or “IBO” (International Bowhunting Organization) next to them.

How is Ibo on a bow calculated?

Principles of using an archery calculator For every inch of draw length that exceeds 30 inches, the IBO value is increased by 10 feet per second. For every 3 grains of total arrow weight above draw weight multiplied by 5 that exceeds the draw weight, remove 1 foot per second from the IBO. For every three grains of additional weight on the bow string, one foot per second is subtracted from the IBO.

How much does an arrow drop at 20 yards?

#4: The further an arrow flies, the faster it drops: Using the 350 FPS crossbow as an example, you’ll notice that an arrow drops 8.5 inches between the 10 and 30 yard marks (20 yards distance), but drops another 19.8 inches over the next 20 yards (from the 30 to 50 yard mark), for a total of 28.3 inches drop over the next 20 yards.
