Sportline sx heart rate monitor

Hi everyone! I recently purchased a Sportline sx heart monitor.... Although I'm not sure if it is working correctly....after an hour of turbo fire it said I had burned 806 calories, than 466 after mowing my lawn. That seems like a lot, more then it should be...wondering if any one could tell me if this sounds right? I googled the brand and it had nothing but good reviews...maybe it is right? I would appreciate any feedback!
