Tennis ball machines are a fantastic way to practice and improve your game, regardless of your skill level. The Spinfire Pro 1 makes it easy to practice a wide range of shots, test yourself with a variety of paces, spins and elevations, and build your mobility and fitness with practice drills. With a number of improvements over the original version, the Spinfire Pro 1 offers things you’d normally only find on a much more expensive machine. It includes internal movement, an easy-to-use control panel and 150-ball capacity – all wrapped up in an extremely stylish and compact design. Key features and benefits Internal movement Unlike most ball machines, which change the direction of the ball by moving the whole machine from side to side, the Spinfire Pro 1 moves internally. This allows for faster re-direction and makes shots less predictable. The internal parts are black to further disguise shot direction. Extreme topspin and slice capability Using counter rotating wheels, the Spinfire Pro 1 operates very quietly and can generate maximum topspin and slice if desired. Easy portability Compact and lightweight, the Spinfire Pro 1 fits in the boot of most cars. The hopper (ball basket) can be reversed to neatly cover the machine, and solid wheels and an extendable handle allow you to pull or push it almost anywhere. Three power options You can choose between our 3 power options, External Battery - machine with external battery pack, Internal Battery - internal built-in battery machine or AC Power - plug-in AC power option. The External Battery machine is much lighter as the battery is separate, this also allows for handy charging without moving your machine, great for leaving it in the car while you charge the battery! The all-in-one option is our Internal Battery machine, you can simply plug in your machine to charge the battery. A fast charger is also available, cutting the charging time to just 3-4 hours! If your court has easy access to a powerpoint, the AC Power plug-in machine with no battery allows for simple plug and play. More power options!
