Help your youngster perfect their game at home or on the court with the Terrasphere Tennis Trainer. The multipurpose trainer allows them to perfect technique by hitting the ball attached to a weighted-base before it returns to be hit again. The standard size tennis ball is attached to an 8m elastic cord, the harder you hit the faster it comes back. The trainer is stabilised by a heavy-duty base which can be filled with both water or sand with a non-slip base for multi-surface play. The tennis trainer is easy to assemble design packs down quickly for compact storage at home or on the go. Give your future tennis star the head start they need to hone their skills on their own time.
