A portable device powered by rechargeable or disposable cells launches baseballs or softballs at various speeds and trajectories for batting practice. These machines offer adjustable speeds, and some models can even simulate different pitch types, such as curveballs or sliders. A common example is a unit designed for youth baseball practice, featuring adjustable legs for varying the pitch height and a large hopper capable of holding numerous balls.
These devices provide a convenient and efficient way to improve batting skills without requiring a human pitcher. This independence allows athletes to practice at their own pace and focus on specific weaknesses. Historically, batting practice relied heavily on human pitchers, which could be time-consuming and costly. The advent of this technology revolutionized training by offering a consistent, readily available alternative, contributing significantly to individual and team skill development. Their portability allows for practice in various locations, further enhancing their value.
