The Tennis Bullet Stroke Extender will establish and control a stroke extension through a target, pass line, and direction. A device has a base and three vertical, foam-made, flexible extensions. Vertical extensions positioned in a straight line, 4 inches (10.2 cm) apart. The device’s flexible extensions are foam, making them easy to cut with a knife to adjust height. The yellow flexible extension in the picture is the target, and the impact sound must be directly above it. “Target” flexible extension can be positioned first, second, or third in the row.
