"The spin, the dip, the curve, the swerve is something unique...Nothing like it."
Drew Keeshan, Goalkeeper Coach FC Dallas
This first photo shows a driven ball from the midfield spot, landing in the back of the goal. The speed is 7 out of 10 (about 55mph = 88kph). The trajectory is realistic for a through pass and the speed realistic for a player to receive.
The second photo uses only a slight backspin plus sidespin from the same position. In spite of a higher speed (63mph = 100kph) and much higher elevation, the ball reaches only the 6 yard line.
The third photo uses the same speed as the first, but with only a swerve, not a driven trajectory. The ball reaches only the 18 yard line.
The images on this page were created by taking high-resolution photos at 9 frames per second of actual serves from the SideKick Techne® Pro, then using Photoshop to isolate just the ball from each frame and superimpose the unchanged ball image at its actual position onto the first frame.
