Stop counting laps and focus on your technique: just tell the Garmin Swim the size of the pool and dive right in. It keeps count of your strokes, length, distance, pace and more, even automatically determining your stroke and calculating your efficiency.Simple and intuituive to use, the Swim can be easily customised to meet your training needs: for drills involving something other than the four main strokes (e.g. one armed swimming, mixed strokes, kick sets) or for timed sets, just a few button presses inform the watch what you're doing and it records your performance. Because it records strokes, pace, distance, time, and calories burnt, your swimming efficiency can be easily calculated: the Swim works out your Swolf score (the number of strokes taken to cover a given distance). In addition to this, using the supplied ANT+ wireless USB stick, it automatically uploads your training data to your PC or Mac as soon as you're in range of it, where you can use Garmin Connect to view and analyse your workouts and track your progress.More than simply a precision training instrument, the Swim is also slim and attractive enough to be worn as a watch. Under the current time display is shown a tally of your weekly accumulated distance, to serve as a motivational reminder of your training goals!
