Looking for a way to gauge your performance at the track or gym, but tired of inaccurate and limited pedometers, battery killing GPS and annoying foot pods? The Silva Tech4O presents the Accelerator watch series that incorporates advanced accelerometer technology. The result is a watch that "knows" the difference between short and long strides and records, calculates, and displays all measurements via the wrist watch. Provides speed, distance, and calories burned during exercise so you can track your progress.
