Review of the Slinger Launcher

For just under $800, the Slinger Launcher (previously just called the Slinger Bag) is a great basic tool for individual practice for beginners and intermediate-level players. One of its best features is the portable, handy multipurpose bag where you can store your playing equipment and personal stuff, so you won’t have to lug around multiple bags when you practice. 

Size & Quality

At just 33 lbs, and with its adequately-sized design, it can fit in the trunk of most cars. Its heavy-duty wheels also make it easier to move the machine around on any ground surface and it will really just feel like you’re carrying some light luggage. 

Made with durable, high-quality materials, rest assured that this piece of tennis equipment won’t disappoint in being a staple in the practice court and can serve you a long time on any court surface even on the outdoors. 

Battery Life

The battery can be charged to full in about 4 hours (significantly less than other mid-range tennis ball machines with around the same playing time), so keep this in mind when you need to be using the machine. Slinger claims that the machine can last up to 5 hours on a full charge, more than enough time for a full practice session. 

Drill Settings

The Slinger Launcher, while it lacks some advanced programmable drills for variation, has settings that suit the practice needs of beginners and intermediate players. The ball machine can feed you balls at about 45 mph top spin every 2-10 seconds, which can be set manually on the control panel of the machine. An adjustable knob can manually set the angle of elevation of the ball from 10º to 40º.

The machine itself isn’t able to move left and right so this is where the oscillator plate comes in handy. Simply place the entire machine on the plate, turn it on along with the machine with the remote and you’re ready to practice receiving balls on both sides of the court. 

Extra Features

It also comes with a special phone holder that can be attached to the handle if you want to record your practice sessions and monitor your form.  It also has a USB type-a port where you can turn the ball machine as a power bank to charge your phone, provided that the ball machine has enough power stored. 

How To Use

The Slinger Launcher tennis ball machine is actually very fairly easy to use. Here’s an instructional video from Slinger illustrating how to use it.

Place it where you want it on the court, typically on either side of the court or on the middle depending on whether you’re practicing your backhands, forehands, or overhead receives. Open the top ball compartment and fill it up with regular or extra duty balls. Open up the bottom compartment where the control panel is hidden and you can turn and adjust the knobs to your desired practice levels and elevation angles. 

If you want to practice receiving balls on either side of the court, you can put the Slinger Launcher ball machine on the provided oscillator plate and hook it up to the machine. Turn on the machine and the plate with the remote and you can practice your receives with its oscillating settings. 

You can also use the machine to feed you balls for when you need to practice your service. Simply place the machine on your side of the court, adjust the elevation knob to a level that you can easily catch the ball and set it to feed you balls every few seconds or so and serve. 

When you’re done or when the machine has fed you all the balls in its compartment, the Slinger Slam Pack comes with a handy ball tube so it’s easy to pick loose balls on the court and replace them in the ball compartment of the machine to continue your session or when it’s time to pack up. 

Cons

While the Slinger Launcher has proven to be a great tennis companion, it does come with a few drawbacks. One of its biggest cons is the lack of variation and programmable automatic drills. The machine can only ever feed you the balls at its set 45 mph top spin.

More serious players might look for ball machines that can provide them with more programmable variations in their drills. Check out our list of the best tennis ball machines
