I have a Maverick Redicheck. Not the new ET-723 but the older model. I had a feeling the reading was off and sure enough, I put in boiling water and it read 232. I was then "thrilled" to learn that I can't calibrate the thermometer. So I'm wondering if A) am I wrong about not being able to calibrate the thermometer, and
is the ET-723 worth getting or are there any other suggestions ya'll could throw at me.
