how far do you stick in the probe lets sai in a pork butt roast w/o bone.i used the temp prob for turkey and it gave me a false reading. it said my turkey was done in two hours i didnt belive it so i checked with my other one and it was only at 140. i checked bothe old and new in boiling water and they were within 2 degrees of each other. it is a z7 with two probes and it is wireless. i was looking at pic on here and it looks like you all put just the tips of the probes in. thanks
