Hey guys, my wife wants to start working out with a HRM. To clarify, she's not riding a bike (well, sometimes) but doing stuff like running and other aerobic activities. So, she has to wear it on her wrist (no pockets on her workout clothes). In the past she had a Polar HRM but the metal backing gave her a rash, which we assume is a nickel allergy. So does anyone know of a HRM that has a rubber backing?
what about a heart rate chest strap? My polar heart rate strap appears to be plastic on the back, but it could be some special compound, I'm not sure. Some of the receiver watches have metal backs, but you can just strap it around handlebars or the exercise machine you're on. Alternately there are some cycle computers which will receive the signal from the polar chest strap, saving space on your handlebar.
I guess I should have been more specific, it's not the strap that bothers her its the back of the watch. And she won't be riding or using gym equipment, she'll be outside. So I was hoping there was a HRM that had a rubber backing on the watch.
I have a Sigma Onyx series HRM that is all plastic. There is no stainless steel back. Sigma also make the PC series HRM's and I'm not sure about them but the Onyx series which have the advantage of being digital are all plastic.
