I am about to use mine for the first time. All 4 probes read the exact sameInkbird 4 probe, very accurate
where do you have all the probes placed again? On racks or in the meat?
It is not uncommon for them to be different in big hunks of meat or in various racks/areas of the smoker.
I use 3 probes my brisket to ensure that 1 is placed well and gives an accurate reading. I usually get 1 of the 3 placed correctly :)
In the meat. That seemed like a lot of variation tho
