BOLA 5oz Practice Balls. Polyurethane practice balls in red or yellow with soft case to protect bats from damage. Dimpled like a golf ball for stable flight. These give the best accuracy and realistic bounce. Yellow balls for better visibility indoors. Red for realism.
The accuracy of your BOLA machine is affected by the condition and consistency of the balls that you use. Do not mix new balls with old ones as the best accuracy is obtained by keeping balls in batches so they are all at the same stage of useable life. If you are using balls which have lost their dimples, they should be replaced. Why not treat your club to some new BOLA practice balls!!!
