Did another run on the new WSM. In the first run I felt that the stock therm was not accurate. This run I put one of the iGrill2 therms right with the stock therm probe. The other iGrill2 probe was at grate level. The stock therm was 30 lower than the iGrill at the same level. The difference from grate to there on the iGrill probes was 5-10 degrees. As is the norm, the stock therm is not accurate.
