This is an excellent heart rate monitor with the standard features (max, min alarms, time in and out of zone etc...) its also an excellent stop watch. I download the data using Suunto's Activity Monitor software - which allows you to export the data to Excel! Plotting HR versus altitude is very useful for training.I only have a few minor complaints: (1) Battery life is terrible - this thing (and the chest strap) eat up 4 batteries a year. (2) When battery life starts to fade interference is a big issue - fortunately the data can be edited so you can remove "spikes". (3) PC interface is serial cable - should be USB. (4) Suunto software is veru buggy and crashes all the time (no data lost fortunately)
