A golf, tennis or baseball training apparatus to align the eyes, striking implement and stationary or moving ball to be struck, upon impact. A cap (10) for the user has a radiation emitting device (16) mounted to project radiation along the vision path. A radiation detector (26), an impact detector (37) and a light signaling device (35) are mounted on the striking implement (38). Processing and decoding circuitry and sound signaling means are mounted on the striking implement (20, 33, 38) or the user. A light or sound signal can signal proper alignment to the user on impact (i.e., essentially simultaneous actuation of radiation and impact detection), and/or can signal improper alignment to the user on impact. The sound signal may be a high or low frequency signal or words from a voice chip. Adjustable radiating beam widths may be used for different levels of skills.
