Got a nice bone-in 5 pounder at Sam's Club yesterday. Rubbed it and put it on at 6:45 AM.
So far, I've had a rain shower run through at 1 hour into the smoke & one of my thermo's went down. I use 2 digital (one for the meat & one for smoker temp as well as 2 analog mounted at both ends of the horizontal).
The thermo was reading the smoker temp...sitting nicely at 230* when it jumped to over 300 then back down to 88 - 89*. Battery change didn't fix it, nor did swapping probes.
So...now I've got 1 in the meat and the 2 analogs. I've been doing this long enough to know the approximate temp the analogs are telling me (I hope!!).
Rubbed meat -
