I have had my S410 for 4-5 years now. I still use the PCCoach that came with the original purchase. However, the latest update remains v 2.3 in 2001. I wonder if Polar now uses other programs to DL heartrate information. If so, where can I get a copy? Would it be free? Or I have to buy it? Afterall, if it ships with the current S410 and the model is current, why not a free DL?
