Huge error at high heart rate. Low pulse rate under the load
Hello all!
I bought wahoo tickr fit, I noticed that it was giving incorrect readings during exercise. When I was out of breath while cycling uphill, it showed my heart rate at 90-100 BPM. In reality, the pulse is 160-180. I decided to test it with a regular chest heart rate monitor (not Wahoo) and apple watch. Under the load the error is about 30-40 BPM, and sometimes even 60 BPM. And the greater the load, the greater this difference in readings. But in a calm state the indicators are identical on all three devices...
Could you tell me if this is a defect or normal? And should I contact Wahoo support?
