What brand flu thermometer

Sounds good guys,thanks for the info,as i said in another thread it does take off quick with a hot bed of coals and has to be watched and i usually set it on a 2 on a hot coal reload then close her up when i think the moisture's burnt off.Mainly don't wanna eat my cat up.I can see with the intake where it is why the coals forward would be good. Dennis,i thank you for giving me good advice on this stove,so glad i got it.
