The smallest and least expensive full-featured tennis ball machine produced in the USA. It’s capable of performance found in tennis ball machines costing hundreds of dollars more. Just like their larger models, it is designed to be lightweight, rugged, and offers years of trouble-free service. It has a 50 ball capacity, fires balls up to 60 MPH, has a variable timer (3, 6 or 12 second intervals) and delivers lobs and ground strokes.
