I am looking at getting either a Maverick 7 or 73, still undecided. My question is that with the 7 it has two meat probes and with the 73 it has a meat and chamber temp probe. Can these probes be used the other way as well. IE can the second meat probe on the 7 be used as a chamber probe, and can the chamber probe on the 73 be used as a meat probe? I have found each for around $40 and each has great functions, just want to get the best bang for the buck. I would probably go with the 73 if both are the same price since it comes with the handy dandy rack clip for the chamber probe...............if all things other than that are equal. Thanks for all your assistance.
