Which two major associations are known for 3D archery?

The two major associations known for 3D archery are the International Bowhunting Organization (IBO) and the Archery Shooters Association (ASA). Both organizations focus specifically on competitive 3D archery, which involves shooting at three-dimensional targets that mimic game animals.

IBO is noted for its emphasis on bowhunting skills and promotes a variety of 3D archery events that cater to different skills and abilities, while ASA hosts various tournaments that often attract large numbers of participants and also emphasizes bowhunting practice and accuracy.

The other associations listed, such as the National Field Archery Association (NFAA) and the Archery Trade Association (ATA), have different focuses. For instance, NFAA includes a range of archery types but is not as centered solely on 3D archery events as IBO and ASA. Meanwhile, ATA mainly deals with archery industry representation and doesn't specialize in organized 3D archery events.
