The Science

We can execute even the most unpredictable ideas!

We studied 1,000 tennis players at mixed levels using slow motion footage. The data on swing efficiency was shocking!

  • Amateur tennis players were off balance on 90% of their shots,
  • Beginning off balance leads to missing the sweet spot 80% of the time
  • Off balance pro players miss the sweet spot 50% of the time

We put them all onto the Pro Swing Simulator for 20 minutes each and the results amazed everyone.

Our entire testing group saw an average increase of 43% in sweet spot hits.

Here’s why most players are only capitalising on their shot 20% of the time

  • The only time you can control the ball placement is when it touches your strings
  • The only time the ball touches the strings entire match is 2 seconds
  • Those 2 seconds determine the winner at every level

How you hit the ball matters, where the ball lands on the court matters butwhere the ball lands on your strings matters most. This is the one skill that makes or breaks a tennis player's career. 

Consistently hitting the sweet spot using our Pro Swing Simulator is the fastest way to improve your game on the court.

Hear what some trusted industry leaders have to say about using the Pro Swing Simulator

“I have used the BJK Eye Coach ball striking system for many of my kids clinics my Love & Love Tennis Foundation conducts. It’s an excellent coaching tool that helps kids learn their stroke and most importantly watch the ball!
I would definitely recommend the ball striking system to all coaches at many levels and P.E. teachers K-5th. This is a game changer for growing tennis.”

“The BJK Eye Coach is the most important tennis tool to developing perfect tennis strokes and perfect timing. Not only did it improve the players I coached but it improved my coaching and gave me a baseline and the foundation to becoming a world class master coach and tennis teacher.”

“I don’t use many training aids as I find playing real tennis the most valuable use of time for player development. However, the Eye Coach is different. It helps players find the right swing path, rhythm, and tempo faster, before transitioning to the court. Players can feel the way they’re supposed to swing, then implement that immediately. This, in my experience, speeds up the stroke and player development process immensely. I highly recommend the Eye Coach for any players or coaches who want to see faster results.”

The root cause of most errors is hand-eye connection

  • A broken swing is a result of not being able to Scan, Track and Focus.
  • Not being able to Scan, Track or Focus is a breakdown of signals in the brain.
  • Training these crucial signals is the missing piece from a perfect game.

When these eye brain signals are triggered we can instinctively get ourselves in a position to Scan, Track and Focus the sweet spot of the oncoming ball.

Our Pro Swing Simulator Drills restore all 3 signals in proper sequence. Resulting in 10x faster progress and 9x as many habit forming reps.
