<p>PURPOSE:To diagnose and improve testee's skill by providing a memory means for storing data of a load center locus for comparation so that an indicator indicates the stored load center locus for comparison and the result of measuring the load center position of the testee. CONSTITUTION:Positions X, Y of the center of gravity of a testee can be tracked while being calculated by a calculating means 31 in a calculating unit 3. The result, if necessary, is indicated on a two-dimensional picture indicator 4 through an I/O interface 32 so that the testee can see the result during his swing. When the swing he tried was the best one he wanted to use for his own standard, it is recorded in a memory means such as internal memory means 33 or external memory mans 35 as a locus of the center of gravity. When the swing is measured and indicated and proper locuses are selectively put one over the other to be indicated, not only player's skill is improved, but also a decise serving to adjust his condition right before his play is provided.</p> |
