New ATA White Target Boards. Available in 3 or 5-prong. These are great demo and new student boards to teach targeting, trajectory and follow through without resistance. A great tool to help in the transition to the colored re-breakable boards. Based on current plain re-breakable white board: 3-Prong board requires only 27% striking force and is intended for younger tigers. 5-Prong board requires only 45% striking force and is intended for older tigers.
