Well, Tony asked me to run some time lines with CS probe and my Thermogen. Looks like the unit is working OK.
He mentioned that if I was smoking meat taken right from the fridge along with putting into a cold CS smoker, cooktimes could be much longer, but comments which I did not factor in.
Will do some more smoking over next few day, see how it goes, but based on tech support, my unit is good to go. Seems I have to get better acquainted with my meat and smoker.
