T-rex recently posted that he did all his sears dome open. I've always seared dome closed and thought that to be the only way, seems not. What I'm wondering is what temp you get at the grid level with the dome open on a sear. I always sear at 700 plus, when I open the lid the flames get bigger, more air, but does the cooking temp drop or rise? Have any of you guys with these temp sensors ever checked this? Like if you got a 700 dome temp when you open up the egg what grid temp is maintained?
