I have had my polar f4 for about 4 months. I also have a fitbit. I dont know if it is my polor not working or what but when I worked out it used to tell me that I would burn about 600 cal same as fitbit. Now its down to 400 while fitbit and myfitness pal still shows 600. So I went to use it last week and all of a sudden my watch is telling me it can not read the HR thing that is on my strap. So I thought it was the battery. I ordered one off amazon and put it in...still not working. Any ideas? I have reset the watch and that doesnt help either...

    Did you somehow change your V02 leve?. That will adjust your calorie burn. I am still not sure what my proper V02 level should be. So I don't know if my FT40 is showing the correct amount of calorie burn.
