Calories burned

When doing bicycling indoor i use the VA 3 and Edge 1000, both «feed» from Scosche Rhythm+ Heart Rate Activity Monitor, on a one hour session i have 20-25% different reading on the calories. All personal parameters are equal in both devices, so which of them should i trust ?

that's interesting.
as i understand, garmin calculates calories based on heart rate... guess they both have diff calculations.

just curious.. but how about the next time, try using the va3 built in hrm and see how much of a difference it is compared to the edge 1000 + scosche?

Will do tomorrow. I planned to do that today, but Zwift servers where down for maintance.

Did a 90 minute easy ride this morning. Used the Edge 1000 with the scoche and the built in monitor on the VA3. Her’s the numbers :
Edge: average hr: 105. Max hr: 126. Vo2max 42. Calories 853
VA3. : average hr: 107. Max hr: 132. Vo2max 45. Calories 677.
Always fun being a beta tester for Garmin. The question still the same, could i trust some of these numbers? Probably NOT.

so can we say the va3 hrm is good enough... just that it calculates calories burned differently.

But i have also read of different weight profiles giving different readings too...
