This watch/belt combo will monitor your heart rate, and be accurate. However, the user interface is pretty clumsy and not very easy to use. Also, unless it picks up the belt, you can't use the stopwatch in "free mode". Not deal breakers, but I would look for one that is more user friendly. Having owned 3 or 4 previous brands, this is by far the hardest to use.
