What are some good heart rate/calorie fitness devices?

Drdmike

I am looking for a device that would calculate how many calories I burn throughout the day. The catch is that when I go to the gym, I do TRX and weight training so the device should be able to calculate that as well. I would like a device that monitor my heart rate too. I know about polar and fitbit but there are so many devices that they make. The most important feature for me is that it accurately calculates calories burned regards of whatever activity I do.
Thanks

I use my polar ft7 for gym workouts, it's not meant to be warn all day though.
