Polar S625X Heart-Rate Monitor Wrist Unit

Polar S625X Heart Rate Monitor Wrist Unit

The Polar S625X Heart Rate Monitor Wrist Unit is Polar's new speed and distance unit, which utilises accelerometer technology housed in a small sensor that you wear on top of your shoelaces.

Polar developed the S625X Heart Rate Monitor Wrist Unit with this technology rather than GPS for a number of reasons:

  • Footpod technology delivers a consistent stream of data while GPS technology experiences occasional interruptions in heavily wooded areas where overhead cover is dense or in urban environments with tall buildings
  • Present-day GPS systems adapted for running speed and distance are larger than Polar believe is acceptable for the serious runner who wants to wear something wholly unobtrusive
  • The Polar system only requires you to wear three items (transmitter, receiver and foot POD) to get speed, distance and heart data while the GPS-based units that offer heart rate now require you to wear four items
  • While calibration is necessary unlike GPS, it's easy because the Polar 625X Heart-Rate Monitor requires this to be done only once rather than the multiple times necessary with similar technology from competitors
  • The future possibilities for running performance data that accelerometer technology can deliver are tremendous and will be coming your way with Polar
  • By an interesting irony, satellites are positioned using accelerometer technology...
