Designed for swimmers, the Gramin Swim watch records all data necessary for swimming training. The swimmer can keep focused on the workout and technique, the watch does the rest. It calculates speed, the number of lengths, calories burned, the efficiency, stroke count and type of stroke practiced. With all this data stored, Garmin Swim is capable of measuring the progress and results of various swimmers during different training sessions. This data is downloaded wirelessly to your computer and can then be reviewed by the athlete himself with the included GaminConnect software .
