The 9 Best Tennis Ball Machines
Practice Makes Perfect
This peak in air pressure ultimately overpowers the resistance from the detent, propelling the ball out of the tube and onto the court.
When it comes to building skill on the tennis court and maintaining your "A game" at all times, having a partner on the other side of the net that never tires of sending a return shot is an invaluable resource. Whether you're just learning the strokes, perfecting that backhand slice, or striving to become the next Serena Williams, you'll need to maintain consistency, accuracy, and power when striking the ball. We're not telling you to abandon the knowledge and wisdom that is delivered from personal coaching, but for those times when you don't have a teacher there to instruct you in technique, what better way to practice on your own than with a tennis ball machine? Dedicated to providing the repetition of constant, high-action ball propulsion, this accessory will simulate the rigors of an actual tennis match.
Tennis ball machines typically come in two main categories: spinning wheel and pneumatic pressure. Resembling an old-style leaf or snow blower, the pneumatic pressure machine consists of an engine with a long tube attached to the end. Typically requiring a lot of power and using an electric motor, the pneumatic machine supplies air pressure to the ball, lodging it within the throat of the tube while a collar holds the ball in place. When enough air pressure has built up inside the machine, the ball is propelled out of the tube and onto the tennis court at high speeds.
Also referred to as counter rotating wheels, the spinning wheel machine is a much more popular design and functions in a similar fashion to the way a pitching machine works. When turned on, the spinning wheel machine first uses an electric fan to draw in outside air for storage in a sealed compartment (or chamber). The air passes through a series of filters on its way into the machine. These filters consist of foam or a screen barrier of some type. Air pressure also builds up inside the chamber. While this occurs, a tennis ball drops from the machine's storage hopper into the chamber where two counter-rotating spinning wheels work to squeeze the ball, keeping it under intense pressure. The ball is then forced into a soft, rubbery, circular tube called a detent, which leads to a small opening. As the ball is lodged in the detent, an airtight seal is formed at the end of the tube. Simultaneously, a plastic flap falls over the entrance, causing air pressure to reach a peak. This peak in air pressure ultimately overpowers the resistance from the detent, propelling the ball out of the tube and onto the court. Upon release, the space within the machine's chamber is then occupied by another ball. This process continues until the hopper's ball supply has been depleted.
A key difference (and benefit) that sets the spinning wheel design apart from its traditional, pneumatically-operating predecessor is in the ability to adjust the speed of its counter-rotating wheels, which allows a player to practice at their own pace. The ability to adjust wheel speed means that a tennis workout can be tailored to suit an individual player's preferences, depending on the type of shot (or spin) he or she wishes to learn and practice.
Finding The Best Features For Success
Because the simulation of real play is important when building skill and perfecting the various strokes, the machine you choose should be versatile enough to deliver shots that you'd ordinarily experience during an actual tennis match. That said, pay attention to the machine's oscillation features. Horizontal oscillation is the most common, as you'll be dealing with constant side-to-side motion against an opponent.
Horizontal oscillation is the most common, as you'll be dealing with constant side-to-side motion against an opponent.
The battery power of the machine is also important, considering that extended repetition of strokes and movements on the court are required to perfect your skill. It is also for this reason that counter-rotating wheel systems are ideal, not only for their range of adjustments, but also because they can offer extended battery life without the restriction of an AC power outlet.
Many of our options also connect to a smartphone for convenient program control, which comes in handy when you don't feel like crossing the court to make a change to the unit's delivery style, speed, or if you simply want the freedom to move around and control your workout remotely. Dedicated remote controls are a useful teaching accessory for the machine when a coach is around, as well.
Next, pay attention to the available speed range and hopper capacity. Most launchers offer a speed range of between 10 and 95 miles per hour with capacities between 50 and 300 tennis balls.
A Brief History Of The Tennis Ball Machine
The development of the tennis ball machine is credited to tennis player, business leader, and fashion designer René Lacoste, known in modern times for his iconic crocodile logo found on articles of clothing belonging to his brand. Lacoste patented one of the first hand-cranked tennis ball launchers in the 1920s at the humble of age of 24 in collaboration with the Dunlop sports company. The design of this early machine allowed him to perform multiple stroke repetitions. Lacoste is also credited with the invention of the first tubular steel tennis racket.
Their speed could also be adjusted to release more or fewer balls per minute.
The first electric-powered tennis ball machines appeared in the 1950s at many tennis clubs, but were not available to the general public. These machines made use of a high-tension spring to launch a bar with a striking head designed to hit a tennis ball to follow varying trajectories. Their speed could also be adjusted to release more or fewer balls per minute.
In 1968, sales executive Robert H. McClure designed and built a new tennis ball launcher called the Little Prince, a pneumatic machine that became one of the first commercially-available launchers.
Today, counter-rotating wheel systems are the favored option of most tennis players, as many are portable with an ability to run on batteries, which certainly comes in handy on the court where access to power outlets is limited.
