The Tech Toc is a simple training tool worn around the waist that provides instant stroke feedback and ensures proper hip position during all four swim strokes. The Tech Toc utilizes a ball bearing in a plastic capsule and acoustic amplifiers to create a sound as the device is tipped from side to side. This audible feedback prompts proper hip rotation and undulation. The Tech Toc also has a Delay Setting which delays the ball bearing, forcing swimmers to exaggerate hip rotation.
