I have used a Polar FT4 for so many years I've lost count. I just love it, but it finally died. I was going to order a new one but can't find it for sale! Does anyone know if Polar discontinued this model? I'd be reluctantly willing to switch to a newer model. I only track the amount of time of a workout and the calorie burn. I also love to check where my heart rate is during the workout. I don't want a complicated one -- hate the learning curve. Any suggestions would be appreciated.
