I have a wireless temp gauge and I was wondering, if I just put it on the grate am I getting accurate temps? Is there something I should use to get the temp of the cooking area?
As MilitantSquatter said above, you'll get a MORE accurate reading if raised so not in direct contact with the metal grate.
What kind of smoker you using? I use a turkey fryer thermo for my UDS. Just drilled a hole just below the cooking grates. It's long enough to reach the center of the smoker.
