What type or brand thermometer do folks prefer to use when measuring mash temperature in a cooler MLT?

I have a long probe dial thermometer from the LHBS, a small dial thermometer from a restaurant supply, and a Polder digital thermometer. The digital thermometer is great in the sense that it is quick and easy to read, but I've found it takes longer to register an accurate temperature, and tends to be "jittery", jumping around to odd temps at times. On the other hand, either probe thermometer seems to be about 3-5 degrees off from the other. They seem more accurate, but they're a little more of a pain to read from inside the MLT.

I've had good luck with the traceable thermo from professional equipment. It has the probe on about an 8' wire lead, so I just insert the probe, and close the lid, with the display outside. They're a little spendy, and some on this board have had bad luck with them, but mine's been working great for a couple of years now.

Thermos have frustrated me greatly over the years. I have come to the decision that digital must go (since most cannot be calibrated, and always showed something different than my analogs). Now I have one lab-grade glass thermometer (pretty cheap) that I use to check all critical temps. I used to use a few to get a more "accurate" idea, but all I got was stress! Get one accurate analog, and RDWAHAHB!

I got the Thermapen from King Arthur Flour a while back when they were having a sale on it and it has been a fantastic addition to my brewing equipment. It is dead-on accurate so I always know the exact temp of my wort or starter. Pricey but the last thermometer you will ever need. I also use it to check my temps when I am cooking on my smoker.

I struggled for months with unreliable themos. Got a Thermapen and now I know I am dead on. Not cheap but worth it IMO.

+1 for Thermapen. I got it for brewing, and found that it's also ideal for baking and any other thing I've used it for. It is not cheap, but quality isn't.

+1 on glass lab thermos. They are dead on and cheap - just use with care.

That's exactly what I like about using my digital.

I did see the Thermapen reviewed here. It sounds awesome but my God man, that thing's pricey.
