I've got one too wrote:
When you say original do you mean NOT the Runner 2 (cardio)? Not sure when v2 came out tbh but its the one I have.
But again, how exactly did you turn HR off? to the best of my knowledge this isn't configurable. What menu options did you have to go into?
Every session I've done I'm sure the HR lockin and display beats the GPS lockin.
Yeah, I mean not the runner 2. You go "down", "down", right, right to turn the HR on or off, and i keep it off until i want to turn it on.
