How close does the ET73 read to the dome termometer? I calibrated the dome probe and it was spot on. I also threw the ET73 pit probe in the water at the same time, it was also spot on at 210*F. However now that I am doing my first smoke the pit probe is reading 30*F higher than the dome probe. I have the pit probe cliped to the dome probe.
Dome is holding a steady 250*F, ET73 has been reading between 276 and 280.
