The Swimsense® is a groundbreaking training tool, which captures critical performance data. The monitor straps onto the wrist like a watch and uses accelerometers, magnetometers and patent-pending proprietary algorithms to identify your swim. Analyze your performance on the device with pace times, distance (meters/yards/laps), stroke count, stroke rate, distance-per-stroke and calories burned across all four major strokes. Performance data can then be uploaded to the FINIS Swimsense® Training Log for additional analysis and historical review. The Swimsense® Performance Monitor provides a revolutionary degree of information, which is key to tracking and improving your swim performance.
