private mismatches of the point of contact with the central part of the grid are controlled.

In these modes, the athlete before each successive strike manually positions the possibly deflected elements after the previous strike in one plane, while the training process itself reduces to the development of stable stereotypes in racket strikes on the ball so that the indicated deviations of the moving elements are minimal or absent altogether .

 In the fourth case, the training racket is used, for example, during pre-warm-up.

Thus, the invention is distinguished by the comparative simplicity of the construction of a means for controlling the location of a Dani tennis ball in a racket net that implements two mechanical, mutually perpendicular moving

soslekeli basic elements of a training racket.

The registration of the excess of deviations of the place of contact from the center of certain threshold levels by means of corresponding readout devices in the form of circular scales and pointers is sufficiently informative for training, the technique of a tennis player’s proper tennis racket, and provided for separate fixation of mutually conjugated pairs of elements using screw stoppers allows to reveal particular deviations of the ball from the longitudinal or transverse grid axes in order to introduce correctives in the action of the sport on.

All this increases the efficiency of training athletes, mainly tennis players, although the invention is positive also in bad MiniTOHe.
