Does anyone know if a Garmin Forerunner and a Polar Heart Rate Monitor interfere with one another? Specifically, I have a Polar S725 and would like to use the GPS function of the Forerunner too.
Only thing left would be to mount a webcam on my handlebars and record my grimace up the hills! 😄
There should be no problem. A GPS works by receiving a time signal from a satellite and comparing the change in time between 3 locations. This signal is always present so I don't see any reason why that would cause any problem. Most devices are also tested for interference and usually do not pass inspection if they are found to have a large degree of it.
