"The OTI Method Requires Dedicated Self-Practice And Use Of Step-By-Step Progressions. 
And The Proton Is The Best Portable And Progression Centric Ball Machine I've Seen, 
Which Makes Training With The OTI Method Easy."
- Florian Meier

Why The Proton Ball Machine

Why The Proton Ball Machine

Self-practice and quality technical work is invaluable when it comes to improving your game.

That's why a ball machine that's small, lightweight, and easy to use is essential for improving quickly with the OTI Method
Most machines weigh upwards of 60-100 lbs, making it difficult to practice wherever and whenever you want. Having the ability to work whenever you want with easy progressions, and then switch to more difficult ones with a single click of your phone means you can maximize your improvements using the OTI Method and the Proton together

Plus, the Proton ball machine is one of the most advanced machines on the market with an array of new technologies. 
Invented by Jonah Harley, a former lead Apple engineer who invented the Apple Pencil, Harley and his team have created a small, sophisticated machine that can loft up the softest of balls at close range for deep technical work, and also reach up to 70 mph and 3,000 rpms for all the progressions you need to become a powerful player. 

A Simple, Intelligent Machine

The Proton ball machine has a simple, easy-to-use panel on the back for crafting the exact shot you need to work with. Or, its free App allows you to program any number or combination of speeds and spins. Plus, it comes with a variety of preset drills that actually help your game. 

A Coach, Whenever You Need It

Have you always wanted an on-demand coach? Someone who can feed you the perfect ball every time so that you can actually go out there and practice? The Proton ball machine makes it easy to get better

Train on your time and at your own pace. Never suffer through bad rallies or stray balls when you are working on technique. Make the most out of your time on court with the Proton. 

Essential Features

The amount of spin even recreational players are creating is increasing every day. New rackets and strings have the balls rotating at ferocious speeds. So why haven't ball machines kept up with this change to the game? 
Now they have. The Proton features high-performance drone motors that spin faster than other machines. This means you can replicate any ball or any opponent

Keep Playing, For Longer

The Proton features a lightweight lithium ion battery that will shoot over 1000 balls. Plus, it comes with a quick swap battery for continued play.
The quick-collapse ball hopper folds up and holds 100 balls. So despite its incredibly compact and lightweight frame, you won't sacrifice ball capacity. 

And the Proton's innovative LED indicator means you'll never be guessing when to split step again. An easily visible light, even in bright sunlight, alerts you when the next ball is coming and it's time to prepare. 

So start playing better tennis sooner. Imagine being able to work slowly and methodically whenever you want - and then being able to practice against any shot, speed, and spin - all with the same machine!

OTI Master Instructor Gregg le Sueur has been using the Proton in his lessons for the past few months.

Your perfect practice partner is now available 24/7 - meet Proton - the tennis world’s most portable and powerful ball machine!

"The Proton is an amazing ball machine. I have already recommended it to all my tennis friends. You can easily program multiple different shots with varying speed, spin and placement. It's comparable to the large, clunky and expensive ball machines in terms of power and spin, but is smaller, lighter, and easier to transport. 

The Proton is easily adjusted using the app on your phone or manually on the machine. It can be slowed down to give you the easiest feed and when I dialed up, it had enough speed and topspin that even a ATP 500 ranked student needed time to adjust!

Its consistent and reliable feeds combined with the long battery life means coaches have come up to me surprised at its capabilities and wanting it to use in their lessons. If you are looking for an entry level machine or something advanced, it's worth considering an investment in the Proton. 

Warning: You Also Need The Right Information

The Proton alone is effective but to get optimal results you also need to understand the most important technical elements and need to know how to use the Proton correctly.
