Yes, a Fireboard. I don't use the Traeger meat probe any more as it is not accurate and my grill temp is close to set temp but off 25+ degrees from actual temp, depending on what set temp is. It gets worse the higher the grill is set at. So if I set my grill at 500f it will only achieve 450f.Has anyone used a second digital thermometer to verify the accuracy of both the internal grill and meat Traeger thermometers?
