The SwimsenseÈ 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 SwimsenseÈ Training Log for additional analysis and historical review. The SwimsenseÈ Performance Monitor provides a revolutionary degree of information, which is key to tracking and improving your swim performance.
