The Swimsense Performance Monitor from FINIS™ is no ordinary sports watch. This watch can distinguish between the various swimming styles of backstroke, breaststroke, butterfly, and freestyle. Simply push start and the watch begins to calculate and record your pace, distance, laps, stroke count, and calories burned. When you've finished your workout, simply sync your watch with your computer via USB and analyze your performance through a variation of charts, detailed swimming data, summary reports, and workout logs.
