What is with the huge difference in temperature! I am using my new ET-732 for the first time. I started my first brisket at 5 am this morning. Now the Egg Gauge says it is a perfect 250 degrees but the Maverick says the temp is 322 degrees! I do have the grill probe attached to the grate with the clip that came with the Maverick could that be the difference? No I did not boil test my egg gauge maybe I should have done that already.
