The only difference between the Aquatic Racket Trainer and Swing Trainer is the length of the handle. The Racket Trainer has a shorter handle, making it ideal for sports specific training in Tennis, Pickleball, Raquetball and Squash. The compact design of the Racket Trainer also makes it ideal for use in smaller, shallower pools. Those wanting to train for sports such as golf, baseball, softball or hockey will likely prefer training with the Swing Trainer given it’s longer handle.
