Just broke my strap and need a new one as I don’t see how this can be fixed. Found Sunnto for about $40.
Not finding much googling except the same things over and over so my search criteria stink.
Bummer. Let me know if you find one that is compatible with a polar 720.
I bought two Polar WearLink straps from heartratemonitorman.com for under US$40 each. I was very pleased with Peter’s service and went back to him recently when I needed a new Polar HRM watch. Peter’s email is Omegabar1@aol.com
I’m just a happy customer living 10,000 km. away from that operation.
I got a suunto belt from SRM usa because the polar belt I was using kept dropping its signal. The signal from the suunto is strong and it has the replaceable battery. Can’t remember exactly how much it was though - maybe $55.
