Polar s3 Stride Sensor™ W.I.N.D. (option)
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 real-
time pace, distance and cadence.
