@Albert: I was talking about getting the Garmin heart rate strap not the Garmin 500. I already ordered the 580P!
@USG Tech: Thanks for the info! I'll email the sales department and ask them.
Depending on how the GPS works for me, a couple of my friends might get the GB-580 too. A lot more affordable than the overpriced Garmin 500.
BTW Thank you GlobalSat for providing a forum to discuss your products, it helps many of your customers!
