Black pitching machine with an adjustable spring mechanism. - Brand: FIELD FORCE - Type: Pitching Machine - Color: Black - Construction: Adjustable stand - Features: Ball launch via spring mechanism Used for practice in junior baseball, for lower grades. It was effective for fly ball practice with soft balls for lower grade children who are still afraid of the ball. You can also practice batting, but we were able to enjoy practicing catching fly balls. It supports urethane balls, perforated balls, and shuttles, but tennis balls were also possible. How about for practice during summer vacation? Even moms can operate it with little effort. Please check the condition of the product in the images before purchasing. The usage period was short and used for a short time, so there is no spring fatigue. A storage bag (image 12) will be included only on weekends. Questions are welcome. Please refrain from disappearing after asking a question. Thank you for viewing.
