Omron is world famous for it’s health equipment. Their Blood pressure monitors mainly Omron BP786 are unparalleled. However, they have only three models in Heart rate monitors. Omron HR-100CN, Omron HR-210 and Omron HR-310. Omron -100CN and Omron -310 are chest-strap monitors whereas Omron HR-210 is a strapless monitor. They are having limited training features. There are in competition with Polar FT1 and Polar FT4 models. The price is reasonable for all the three models from Omron.

First time buyers, not sure what to expect and want to spend reasonably then you can opt for Omron HR-310. If you want Strapless then go for Omron HR-210. I will not recommend Omron HR-100 CN, when compared to other two models, the value addition by this model is negligible. This series is good for its cost. However, if you are willing to spend a little more then you can opt for Polar FT7, FT4 and FT1 series or Polar FT80, FT60 and FT40. These two series from Polar are very good choice for heart rate monitors.
