I'm on my second GMG Davy Crockett trying to get a handle on the temp difference between it and my thermometer, iGrill II. GMG cs has been trying to figure it out with me, even swapped out with another grill. I've got over four hours total on the phone with them, and am no closer to trusting the temps enough to smoke anything yet. I've done the home calibration with ice and boiling water multiple times and always come up with 32 and 210 on the iGrill.
At 150 on the DC I get 176
At 200 I get 232
At 225 I get 287
At 300 I get 395
At 350 I get 486
I've tried multiple areas on the grates but all those numbers are directly over their temp probe. The iGrill sits about 1" above the grate which is 1" above their sensor, 2" total. Is there something wrong with my thermometer? I've used it many times on my old Camp Chef with total confidence until the grill died, then got rid of it for the Davy Crockett, thinking it would be an upgrade. Both GMGs were brand new in the box with the newer one piece grease tray, so current stock.
