I picked up one of these today:

In hopes of keeping better track of the temperature in my smoker, I dropped the probe of this thing down the chimney of the smoker and adjusted the amount of wood and the airflow until I achieved a consistend 225 degrees F (+/- about 5 degrees). Then I looked at the built-in coil thermometer in the smoker hood and saw that it read about 20 degrees lower than the electronic one.
No wonder my stuff has been coming out of the smoker over-cooked the last few times I've used it!! It took me about a third of the charcoal to reach 225 on the digital than it did on the built-in one!! I think the error gets greater and greater the closer the built-in gets to 225. I bet I was cooking with temps closer to 300! That makes a big difference in the way meat comes out of the smoker!
We'll see how these baby backs turn out using the electronic thermometer to regulate smoke-chamber temps.
