FAQs

Why buy a tennis ball machine?

Tennis ball machines are the ideal, reliable partner for beginners and experts alike and they're available whenever you are. Beginners benefit from the repetition, precision, and consistency of ball machines. Such repetition develops basic skills and muscle memory - essential building blocks for a developing game. More advanced players can take advantage of controlling spin-style, positioning, high speeds, feed rate, randomisation, and a host of other specific attributes designed to challenge and improve your ability.


How does it work?

Spinshot tennis ball machines use a pair of counter rotating wheels. They spin at high speed to propel the ball. A less effective method is pneumatic propulsion which uses a similar technology to a vacuum cleaner in reverse. The problem with pneumatic is it's noisy, it can't provide spin (without the use of an adaptor), has low top speeds and is generally outdated. Most pneumatic machines have now been discontinued.


How do ball machines create ball spin?

Our machines generate spin on the ball by revolving one counter rotating wheel faster than the other. So if the top wheel spins at a higher speed than the bottom, the machine will impart topspin on the ball. If the bottom wheel spins faster, you will get a slice. Some machines cannot create spin? Some tennis ball machines use the counter rotating wheel system, but choose to place the wheels on horizontal sides of the ball, rather than on the top and bottom. Therefore they are unable to get any top spin or slice.


What is random oscillation?

Random oscillation is where the tennis ball machine replicates a match situation by shooting balls randomly around the court. This allows a player to focus on footwork, fitness and practice shots in a more realistic environment.

 

Why does the machine move on the court in use?

This could happen on some slippery courts when the external battery option is used. When the battery is taken out of the machine, the machine may be too light to be stable. It could move a little bit due to recoil when the machine shoots out the balls. To keep it stable, it is suggested the user either puts a weight in the battery cage, or hangs the battery or other weight on towing handle to increase its weight.

 

How to position the machine before use?

For The Plus and The Player model, the machine will start a power-up initialization after you turn on the power.  This initialization will turn the machine to a factory preset direction. When the initialization is completed, the user needs to position the machine in the PROPER direction to the baseline. For most cases, the user can first position the machine perpendicular to the baseline, then try the horizontal oscillations by changing HORZ value between 1 and 20. If the machine sends the balls out wide to your left side, you should accurately re-position the machine facing more to the right side. Similarly, if the machine sends the balls out wide to the right side, you should properly re-position the machine facing more to the left side. This is just to make the machine shoot balls evenly across the court. So next time when you use the machine, you know which direction you need to place the machine.

 

Can I use any type of tennis balls in a tennis ball machine?

Please avoid slow, oversized balls designed for kids, these can cause the machine to jam. You should also replace your tennis balls once they have lost too much felt, otherwise they will not be propelled properly.

To get the most out of your machines, we recommend you use pressureless balls. Most typical tennis balls are pressurised which become considerably flatter after a couple of days of hitting. If you throw these old balls into the tennis ball machine, you will get varying results. For example on the same machine settings a flat ball may hit the net whilst a new ball would land on the baseline. Pressureless balls avoid this and are designed to have the same bounce and shape for years to come, they only need to be replaced when they lose their felt. The average person will get at least 1 - 2 years out of pressureless balls (depending on court surface, amount of usage, etc).
