Body Media device vs MyZone

Options
Hello, I have a MyZone chest monitor device from Snap Fitness. My trainer has both a Body Media device she wears on her arm and a MyZone chest monitor.
Both tell calorie burn. But after our cardio step class the MyZone shows a higher calorie burn... 500 vs 400 from the Body Media device she wears around her arm. I know Body media does not have heart rate like the MyZone does.
Any body know why the big difference (100 calories ).

which is more correct???

    I have myzone too also from snap. I think that because it reads heart rate it is more accurate?

    I have a my zone as well for my gym and I agree with Wubbie they told me when I bought it, that its more accurate because it reads the heart rate
