Looking for a remote thermometer. I know from reading this forum that the ET-732 is the way to go. I have an auber PID temp controller on my electric smoker so I don't need a dual probe because the PID keeps track of the smoker temp. Currently I use a regular meat thermometer which requires me to open the door to check the temp. Would the ET-705 be what I need? Has anyone used one? Is it a good product?
