I am curious what some of you think about the use of a heart rate monitor. When working at the store, I sell many of these but typically, to fitness runners who are looking to get in shape and want to gauge progress using the heart rate monitor. Rarely, does an elite runner/triathlete, etc. come in and buy one. It could be that these folks get them all on the Internet or perhaps, another factor. I have not thought about it until recently.
Anyway, please share your opinion one way or the other.
