^^ Worth re-reading ^^
The BBQ-thermometer world is fairly small compared to all the other uses for thermometers out there. Most are simple bimetal units because they are cheap. Digital thermometers ironically, have more mechanical challenges because of the probes. They also have a software challenge.
Mavericks have also been sold under different names. Mine has one port that always reads the wrong temp. I've switched probes (with the 733 they are identical) and that one port always reads differently.
If you visit the Thermowroks site, you quickly realize the cooking thermometers are a happy accident to their core business of scientific measurement.
