@dr-suunto If you are purchasing a belt, strongly consider the Suunto. The memory feature is more significant than you might think. If you temporarily lose connection between the watch and the belt it will fill those in when the exercise is finished. You can use the belt alone for sports where you may not want to wear the watch in the gym for example. Finally, the sensor on the belt is very small and the only one I can wear for long distance races without having chafing.
