Fair enough. However, that does not answer my question regarding grate temperature versus stack temperature.now as to using thermometer's for measuring meat temps , if your new to cooking /smoking, i can see that you might need to use them for your 1st few cooks but part of learning to cook is learning how to tell when meat is done and after a while you will get the hang of being able to tell how done meat is by both the look and feel of it , in my case after 40 years i have 0 need for thermometers other than the stack temp
I don't cook in my exhaust.
So, I prefer to know what the temperature is where the cooking takes place.
