New to smoking and bought an MES 30 for my first smoker. Using it for the 2nd time, first time using my Maverick wireless thermometer set. I have my smoker set at 235 degrees which it seems to hold fairly well according to the control box thermometer. My Maverick however fluctuates wildly from 199 to 250 and never really settling down to a constant temp. Not sure which thermometer to believe and I find it hard to believe that the temp is fluctuating that much in the smoker. Any suggestions on how to get control over this? Thanks.
