The Ergo Series provides three watches to suit the needs of all people with active lifestyles. As we all know, a heart rate monitor is the greatest training tool for athletes and exercise enthusiasts. By identifying target heart rate zones, users can more effectively push themselves without overtraining.

Using Acumen's Fluid Check system, the Hydra Alert Series help athletes perform at their best. The Fluid Check system analyzes body type and the relative temperature and humidity of the active environment to alert users of fluid loss during exercise. Most people drink during exercise only when thirsty and often times by consuming more water than the body can process. By making users aware of fluid loss, it becomes possible to rehydrate before performance suffers.
