The Tech Toc is the only device that allows swimmers to gauge the position of their hips with relation to their hand and body position using sound and feel. The Tech Toc consists of a ball bearing within a plastic capsule that contains acoustical amplifiers at each end. The device allows swimmers to hear, as well as feel, the rhythm and pace of their stroke pattern and technique. As the ball hits the acoustical amplifier, it provides the swimmer feedback on their hip rotation and movement.
