I have correspondence started with Wahoofitness, but am wondering if anyone else has seen this. After a short time, my HR display fluctuates over a very short range, no matter what the effort. At first I though, do I need to go to the ER? I tried the usual wash the strap, wet the contacts, short and reinstall the battery, etc. But sometimes works, sometimes doesn't
The graph below explains it better that I can with words. Red is elevation and blue is heart rate. Very hilly and difficult ride of 65 miles and 5800 ft of climbing. All at no change in HR!
