I had a heck of a time last night. I decided to smoke 4 pork butts overnight. I have two Nu-Temp remote transmitter probes and one Taylor thermometer. None of them agreed, and one of my Nu-Temps was saying my pork butt was over 300 degrees after being on for a couple hours and the temp kept going up and down like my blood pressure. I stuck both nu-temps in the vent and they were practically 100 degrees apart! I decided it's probably time to order replacement probes for the Nu-Temps. Anyone know where I can get them?
