Couple of weeks ago I bought a 30" MES (old version) from Lowes. During seasoning, I noticed that the temps the MES were showing versus my ET73 were off by as much as 50 degrees. I moved the 73's probe around to various spots and still got 30-50 degree differences. Is this normal?? Any fixes?? Second question: Last night I smoked some ribs, water pan 3/4 full. The ET73 showed what I would call huge fluctuations in temp throughout the smoke. I did the 2-2-1 for baby backs. Example, If I set the MES to 190 degrees, the 73 would read 220...perfect. But, when the smoker would reach its mark and shut off, the 73 would drop to around 200, then when the smoker would kick back on the 73 would rise to sometimes as high as 250 before once again settling back to 200 or so. Never would hang between 220 and 230 degrees. Is this normal? Do I just have a dud? By the way, during all this, the MES probe never varied more than a few degrees. Ribs turned out pretty good, tender and great tasting, but very dry. I'm not sure I'm real happy about my purchase. I'm gonna try the brick thing, but I thought a mostly full water pan would help equalize the temps.
