Needed a good and cheap heart rate monitor for my Laufträning. Since I have chosen for the Polar FT1. But I was a bit skeptical because of the one-button operation. As, however, turned out to be wrong, the operation is a breeze. Took about 5 minutes to complete. The pulse was after a few seconds. recognized, but works only with exercise recording. Switching zwichen pulse rate, training time and time is working properly on the approach to the chest.
