So in my research I found thought I figured out that Rec Teq had a better controller because it is a PID controller. That it vary +/- 5 degrees because of this. I was reading last night that new Traegers (Pro 575) not only have a PID controller but their new DS controller has a DC motor to make it stronger. Now I'm so confused. Can anyone shed any light on this issue? Any help is appreciated.
