I use wired probes on a very limited basis. Usually on my pellet smoker and when I'm smoking something like a butt and it's cold out and I'm lazy. Sausage smoking is another good example when to use them. On my stick burner and most other cooks no matter what pit I'm using I like the idea of being more primitive. I do temp meat and check for tenderness using I instant read thermometer. Properly calibrated it's the way to go. As far as the tel Tru. They are accurate. Maybe not as accurate as laying a wired probe on the grate but that's not needed either. People get hung up on this idea that their pit needs to be within 2° of set temp. That's ridiculous and not achievable.
