ok, smoking a couple of picnics in the UDS. I generally use the dial thermometer that I installed. It is BBQ after all and not rocket science. I decided to see how accurate the indication was since they are known to be off. This is the drum temp, not the meat. The picnics just went on about 1 1/2 hours ago. I want to do a hot and fast method so I am looking for about 280.
Dial says 270ish
Instant read says 284
Probe 1 says 292
Probe 2 says 309
A lovely clear 10 degree difference between each of them.... Grrrr....
