I hope that Edge 500 and 520 are similar enough for my question to make sense also here in the Edge 520 forum.
My current wireless heart rate sensor from Polar works fine with my Edge 500, but I don't like the effort before any cycling, to "install" it below my clothes. Therefore quite often I just don't use it.
A wireless sensor reading the heart rate from my wrist or my fingers would be much more comfortable.
Is there something like that using the same wireless protocol with my Edge 500? And if possible, not an expensive health checking system, if I may say so, but just something simple and cheap measuring and transferring the heart rate.
Thanks for any help.
