So I fired up my new WSM today since I plan on smoking something tomorrow and wanted to do a test run. I picked up a Maverick ET733 off Amazon. I set up 1 probe on grate during test run to check difference between built in Weber Dial Temp and Maverick and I'm surprised at results. Weber dial temp as I'm typing this is 325. Maverick grate temp is 385. Maverick probe in lid vent is 415. I know these are above smoking temps. I had all vents open so it we getting hot. Now I would expect lid temp to be higher than grate temp which Maverick does indicate, but is it typical for the built in thermometer to be that far off? Which thermometers do I trust? I'm thinking perhaps I should try and calibrate the Maverick thermometer to better gauge of its accuracy.
Also, I don't think this matters, but I did not fill up the water pan. I do plan to do so for cook tomorrow though.
Does anyone have experience with the Maverick?
