So I smoked [destroyed] a brisket flat yesterday, came out over done and no good (I haven't made a good brisket yet though, still working on it, everything else I have made is good though). During the crutch I saw the internal meat probe was climing pretty rapidly. I saw it hit 200 and I knew it was way too soon, so I moved that probe to a different spot and it was still reading 200. I then used my instant read pen thermometer and it showed 190. When I pulled the brisket out that night the pen thermo was reading 203 (where I wanted it) but the Maverick was reading 213!! Today I tested all 3 thermometers in boiling water (the pen thermometer, the smoker probe on the ET-73, and the meat probe on the ET-73). The pen thermometer read 211.5-212, great. However *both* probes on the ET-73 read 216. I purchased the ET-73 in May 2012, and it's been through maybe a couple of dozen smokes. Do you think it's time to replace the unit? I was thinking about just replacing the meat probe, however the fact that the smoker probe was reading 216 as well concerns me. Any thoughts?
