New Archery Products introduces the New ThunderBall™ Magnetic Nocking System. Unlike conventional nock systems, this new magnetic nocking system virtually eliminates the effects of string torque and uneven nock travel for increased accuracy, better flight and deeper penetration. It is durable and installs in minutes. The ThunderBall™ Magnetic Nocking System has an index tab for fast and easy vane orientation and it fits most popular carbon and aluminum arrow sizes.

The ThunderBall™ Magnetic Nocking System is available as a starter kit that includes the ball, 6 nocks, a wrench and a plastic nock for fletching. Also available are replacement packages in 12-packs for the nocks and a replacement ball package.
