I have an Ivation dual probe that is same as a Maverick 732 and also have a ThermaPen. I have boil tested and ice bath tested both probes of the Ivation and the ThermaPen and all are within 2 degrees of each other. That being said, whenever I do a cook my Ivation meat probe says that I have reached my desired IT but when I check with the ThermaPen it has been lower by as much as 30 degrees. Can anyone offer an explanation?
