Abstract: A baseball bat instruction accessory unit to teach the proper technique for hitting a baseball. The unit is held by an instructor and includes a handle or gripping portion, a connecting portion and an impact portion, which is essentially perpendicular to the gripping portion. The unit is made of still sheathing material, such as plastic, with the impact portion highlighted, as by white or brightly surface treatment. The sheathing material allows the instructor to "feel" the quality of the swing by the pupil. Alternatively, the hollow core of the sheathing material may contain wooden or metal dowels to withstand high impact forces and provide more stiff resiliency. The dowel may be made in two parts, spaced from each other to prevent the full effect of the impact forces being felt by one holding the handle.
