Cooking my first Butts right now. I have my Maverick clipped on grid and probed into the Butt. The temp on the Maverick and the Egg thermometer were both around 210-220 degrees, if anything the Egg thermometer was a couple of degrees higher than the Maverick. About 3 hours into the cook the Maverick began climbing, reaching well over 375 while the Egg thermometer never moved, and the Egg did not seem to be any hotter. A few hours later, as the Butts reached 175, I bumped the Egg draft door open and now both thermometers read about 275-280. What gives? I clipped the Maverick on the grid, next to the Butts. Should I have suspended it above? How could there be a 150 degree difference at one point in the two meters and now they read the same?
