I don't like anymore wires and gizmos on or around the cooker than I
need to have. I use a Polder in the meat itself and run the wire out
the top vent. Due to the amount of smoke it will inhale over an
average 15 hour smoke, I have found that if I loosely wrap the braided
line with foil until it is about 3 inches our of the cover it is easy
to clean up. Just throw away the foil.

If I want to know what them it is in the cooker, I installed one of
these about 1/2" over the top grate:

It isn't this one exactly, but it is close. I bought mine down at
Academy for about $15 and it works like a champ. And with a 2 1/2"
dial, I have a chance to see it from where I am sitting rather than to
get up and walk up next to the cooker.

Here's a tip I got somewhere else. These thermos have a retainer nut
on the back of them so you can attach them to the lids. Orient the
thermo so that the desired temp will have the needle at the 12 o'clock
position. That way all you have to do is get quick visual when you
are walking by, no worries about what it reads unless it is off the 12
position.
