The Tech Toc is a simple training tool worn around the waist that provides swimmers with instant stroke feedback and ensures proper hip position during all four strokes. Made of a plastic capsule, the Tech Toc utilizes a ball bearing and acoustic amplifiers in order to create a sound as the device is tipped from side to side. This audible feedback lets swimmers hear and feel hip movements and notify them of proper hip rotation and undulation. Utilizing the hips and core muscles is one of the best ways to create an efficient stroke. The Tech Toc also has a Delay Setting which delays the ball bearing, forcing swimmers to exaggerate hip training.
Rotation is one of the most commonly used descriptors while coaching freestyle and backstroke. The person who is able to swim “tall” in the water is someone who maximizes their rotation and makes themselves as long or tall as they can be from the tip of their big finger to the bottom of their opposite big toe. The timing of the rotation is absolutely critical in achieving maximum enlistment of core strength, which translates to more power and more distance per stroke.
