The Hurricane Category 4 maintains the snap-back action of the original Hurricane with a sleeker design, additional power band (4 total) for fast-back action, and a high visibility impact head. Designed for baseball or softball swing training, the Hurricane Category 4 allows batters to develop swing power, technique and speed with a stationary or moving target. Can be used for static tee practice or as a dynamic moving target. Adjustable height for virtually any player or ball position. Multi-twist mechanics provide feedback on bat speed and power. Easy setup and storage. No tools needed.
