AccraSpeed Sports Trainer is wearable like a watch and it responds to outward centrifugal force. This aid aims to provide proper warm up, systematic velocity and technique training. It gives players a way to feel and hear acceleration through the impact zone.

It offers four levels of training: warm-up, technique/rhythm/tempo, strength/endurance, and consistency.

The dial on the AccraSpeed correlates to swing speed with a golf club so you can find the setting that only chirps at maximum velocity or you can increase the sensitivity to see exactly where in the swing you load the club or perhaps release too early.
