I did a brisket last weekend which was my 4th smoke and my second smoke using a maverick 732 and while I was waiting for it to come up to temp I couldn't figure out why the maverick was reading 30 degrees hotter than the one on my WSM so I went
with the maverick's temp and threw my brisket on when the temp stabilized at 216 in order for me to get it at this temp I had
the 3 vents on the bottom 1 closed 1 90 percent closed and the other at 80 percent closed and the top vent 50 percent closed, this didn't seem right to me but I went ahead with the smoke anyways for about another hour and a few beers later I just knew there
shouldn't be that much of a difference between the two after all it was a new smoker and a new Maverick so the more I thought about it the more it bugged me so I went ahead and pulled the cover off to check the probe and when I did I seen my rookie mistake, now this is probably common sense to you pros but when I put the probe on the grill I wanted to make sure to leave enough room for the brisket
thus the reason I stuck it on the very edge of the grate which naturally is where the direct heat is because of the gap between the water bowl and the side of the smoker, once I moved the probe where it was actually closer to the meat and over the water bowl both thermometers were dead on, by the way I'm using sand in my water bowl. Lesson learned.
