BILLIE JEAN KING'S Eye Coach Tennis Simulator Replacement Arm, Tennis Training Aid, Rubber, Black

The full unit $180 is too expense. I built my own base use a bucket, and a bag of cement, a short 2x3 wood stub(2 feet, i used a leaf over metal). Going to add two wheels to the base for easy pull it around(heavy).

Great for teaching topspin forehand. I made my own base since it was too expensive to buy with their base.

Modified to fit in and use in weighted patio umbrella base. Increase that hand to eye coordination. Practice backspin and top spin shots. Gives the repetition you need to perfect these shots. Great product. Use for pickleball or tennis.

When I read that I could buy the functioning portion of the eye coach for $49 dollars, I decided to buy the replacement head and build a base. The DIY base cost around $25 dollars bringing my cost to around $80 plus my time. Works fine, and saved over 140 dollars with the DIY project.

Good.

I read that a person built their own base for this part, so I did the same thing. I had a weight at home and metal rods I used as legs and built the base for $50.00. A little engineering talent helps. Works fine for my tennis students.
