I own a Forerunner 245 and a HRM-Run that work together seamlessly.
My father after a myocardial infarction needs heart monitoring during activity, so I'm borrowing him the watch and the strap for the time needed.
My question is:
Can he use my HRM-Run, if he buy a simpler watch like Forerunner 35 or 45?
Of course he doesn't need running dynamics like me, only accurate heart monitoring during activity.
Is compatible over ANT?
