The Tech Toc is a friendly, introductory product to hip training. It utilizes a ball bearing inside of a plastic capsule containing acoustical amplifiers at each end. As the swimmer rotates their hips while training, the ball hits each end of the capsule, providing the swimmer audible feedback on their hip rotation and movement. The device allows swimmers to hear, as well as feel the rhythm and pace of their stroke pattern and technique. The Tech Toc can be used by any age group for any swim distance or stroke.
