The Polar Pro chest strap adds an electrode sensor for heart rate measurement to the previous product, increasing the accuracy of heart rate measurement.Silicone has been added to prevent it from slipping down, and the sensor clasp has been newly improved so that it will not slip off even during intense or long-term exercise.The electrode part that comes into contact with the skin on the chest is made of a thin, soft material that improves the feeling of wearing and dries quickly after use.This strap is compatible with all Polar heart rate sensors with the same snap construction.
