Billie Jean King's Eye Coach

Correct focus and balance at the point of contact is 80% of your tennis game. It happens in the final three feet too fast for any human to teach. Until now. Welcome to the Eye Coach! Recent studies show that focusing incorrectly at contact is the #1 cause of miss-hits, loss of balance, power and accuracy. It's the last 1/10th of a second before you hit that counts too fast for any human to teach. The Eye Coach is the only tool that can train your eye to focus properly in that critical split second.
