ET-73 redi-chek.........got one for christmas and i LOVE it
plus its remote.........so i can check temps IN the house.....thats nice when smoking in the winter time
it also has high and low alarms........for when the smoker gets too hot, or the fire dies out........
it has two probes......one for the smoker, and one for the meat........
the alarms are GREAT, when doing a all-nite smoke, like smoking a brisket....those normally run 16 hours, so with the alarms......i don't have to baby sit the smoker........i can catch a few winks, and when the fire starts to go out, the alarm will go off, and i can climb outta bed, and tend to the fire.........
