I am just starting to research smoking, etc and am planning on getting a Weber smoker and am looking towards a Maverick ET732 (or maybe a 733??) thermometer. On reading review here and on Amazon, it seems the Maverick has some short comings, although that may be an inaccurate statement! If you calibrate it with freezing water, is there an adjustment on it that you can use to calibrate it, or, if it is off say 5 degrees, do you figure it will be off 5 degrees when in use eg 225 degrees instead of 230 degrees? It seems like an accurate thermometer is a must in smoking and I want to be able to make sure the one I decide to buy is just that, particularly if I'm shelling out 100 bucks for it. Thanks for any info.
