So I have my new Maverick ET-732 on the way and I had a question arrise. I know that the probe needs to be over one of the plate setter legs but does it just rest on the grate? Shoulde I get a little holder thing or something so that it is just hanging out in the air somehow? As far as wrapping the probe is concerned do I need to wrap the entire wire in aluminum foil or just where the probe needle attaches to the probe wire? Thanks in advance.
