Tips For Use:

1. The Fence Trainer is intended for beginners to advanced beginners learning swing heights and contact points for groundstrokes, serves, overheads, and even volleys.
2. The balls are foam-filled for maximum durability, and should not be left outdoors in rain or freezing weather. In the event that replacement balls are required, contact our offices. Carefully cut off the old bal and secure the new one by tying a knot.
