Description

• Going beyond speed and distance to provide insight into the running stride itself, the s3 stride sensor is a durable light-weight module that measures just 55 x 39 x 14mm.
• It can be mounted securely and unobtrusively to training shoe laces or placed inside the specially designed mid-sole cavity in the adidas Fusion running shoe.
• The s3 stride sensor is activated automatically by the RS800 wrist unit at the beginning of a training session and transmits speed, distance and cadence data to the RS800 wrist unit using Polar W.I.N.D. 2.4GHz wireless transmission technology.
• The s3 stride sensor has user changeable battery with a minimum lifetime of 50 hours during normal use. Remaining battery life can be checked remotely with the Polar ProTrainer 5" PC software. Low battery warnings will also be displayed on the RS800 wrist unit.
• Polar s3 stride sensor is the most effective technology for tracking realtime pace, distance and cadence.
