Biofeedback enables the client to hear a pleasant tone when they are in the correct position and an obnoxious tone or silence when they are out of position. This can be tested at any point during the golf swing. To hear a pleasant tone – indicating that you are in the correct position you must be within the parameters of where the LPGA and PGA tour pros are at that exact time in their swings, or settings that your trainer customizes for you. As you move through the swing repetitively you will teach yourself how to get in the proper position by seeking the pleasant biofeedback tone. It is like magic. It is a GREAT teaching tool.
