"P.T.S. Home Page"
Simulators are used in several
sports for a better understanding of
the basic movement, as for example in wind-surfing, canoe, golf and bycicle.
Their goal, as many people might think, is to improve tecnique and not
to substitute the sport at issue.
The P.T.S. was created for this purpose: it'll help the instructor to teach
the tennis basic tecnique and it will also allow the pupil to practice at
home by himself, what he has learned with the coach.
