The Unique Fill & Drill tennis trainer for tennis training includes a solid base that stays in place when filled with water. The elastic cord winds around the base, and the ball locks into the base pocket. The trainer is a great teaching tool for beginners and intermediate tennis players.
It sets up virtually anywhere and stores easily--the cord and tennis balls fit right into the rugged, non-slip base. The durable Kinetic cord stretches up to 30 feet, with dual-swivel connectors that keep the Kinetic cord from tangling as it stretches up to 30 feet and then returns the ball to you.
Unwrap the cord, hit the ball as hard as you want, and the ball bounces back to you. -The harder you hit the faster the ball is rebounded to you Rubber cord is 15 feet long and stretches to 30 feet for hard-hit balls. To shorten the rebound, wrap some of the cord around the base to your desired length
