I want to use a HRM to follow the Friel MTB training bible. It's going to need to have zones that I can set to do this. The Sigma Onyx Pro looks good. Can you confirm this HRM will work for what I want to do? Or should I get something else. It needs to be the wristwatch style so I can use it for skiing in the winter. Thanks!
