I'm new to the life of smoking food, I've been reading Jeffs course, but I have a question. I have a digital thermometer that has a silicone insulated wire, is this safe for using in the smoker or do I need to find one that has a metal braided covered wire? I just bought my smoker from the bass pro shop, it's a propane vertical smoker the Landmann smokey mountain 2 drawer model. If I do need a different thermometer which one is highly recommended? Thanks
