Tourna Tennis Sport Training Aid

Fill-n-Drill Tennis Trainer: When filled with water, the base becomes heavier than any other Tennis Trainer on the market. Very light when empty, it can be stored in player's bags and taken along. The elastic Compression rubber cord winds around the base and the ball fit securely into the base pocket. It is a great teaching tool for beginners and intermediate players.

A strong rubber cord returns the ball. No skid base. Can use on clay courts. Just drive a spike into court and position the handle over the spike. When filled with water, it's heavier than a concrete-filled trainer. When empty it can travel with you. Practice will improve your game. Trainer made in Taiwan.
