Has anyone used one of these, i bought one and it works but unsure about the temp being true, i smoked 3 13# turkeys for thanksgiving and it seemed to be reading ambient temp more than food temp. the probe was fully inside the thickest part of breast. it was reading high to me, so i removed it and stuck it with my thermo fork and the temp was about the same. I just went with my instincts and kept them on for a while longer, took them off later and they came out fully cooked and juicy. Today I am doing 2 racks of babybacks, I usually smoke them for like 9-10 hours, i also threw on a 4 lb tenderloin and it has been on for 3- 3 1/2 hours and at 165 on temp. is that a normal?
