UDS Smoker Question
I am new to the whole 'real deal BBQ' (and forums in general) thing and the bug has bit me pretty hard. I have a small Brinkmann vertical water smoker and was thinking about upgrading to a UDS, but, I wasn't exactly sure how it works or is considered to be an indirect cooker. Basically I have been reading up on all of the information I can find about the UDS on this forum and the rest of the internet and I noticed that some say to use a diffuser or water pan and others say not to. So my question is if you do not use a diffuser or water pan of some kind then how is it an indirect cooker/smoker and not a direct cooker like an oven?
Thanks in advance and sorry for being sooo long winded.
