About to buy a KAT Vault smoker. Please look up on Google to get a idea of what I'm talking about and looking at. The stock thermometer is a DOT and it's got the probe. It's mounted on front of smoker. My question is, is it just a thermometer for internal meat temps only or does it do both at same time? Please refer to picture on GooglGoogle of Kat vault smoker if my image don't load, also first vault for me so any tips advice and Intel would be awesome.
