Tomtom multisport cardio does not pickup heart rate acceleration
I'm using a tomtom multisport cardio for about half a year now, both treadmill mode while spinning and bike mode on my racebike outdoor. The latter has a bit of a problem. As long as I keep on riding there is no problem, but when I wait for a traffic light, my heart rate drops. Quite normal, and the tomtom does show the drop. But when the light turns green and i go riding my bike again, the heart rate should go up, but it lags and stays on a low level. Eventually when I have picked up my pace again, the heart rate is about half of what it should be, and it stays at that level.
I have tried a couple of ways to circumvent the problem:
1. Stop and and let my real heart rate drop until it reflects the tomtom heart rate and then start peddling slowly until I get back on a normal excercise level again
2. pull of the watch until it receives no HR signal anymore and then put it on again. Sometimes this works
If my ride does not contain to much stops at traffic lights where i have to wait long so that my HR drops below 100, i have no problem, but waiting for a train is a killer :-(
I am reluctant to turn off the watch and turn it on again, because i'm registering the ride to upload it to Strava....
anyone having the same problem ?
TOMTOM, do you have a fix for this problem ?
i´m about 50 years old and on outdoor rides my hr is about 150, peaks at 170-180
p.s. while spinning i have never encountered this problem, probably because my HR never drops below 120 during the excercise.
